1. Homo floresiensis ("Hobbits") 

 

Location

 

Location of Flores island in Indonesia.

Excavations have been going on at Lia Buang cave since 1965 but it was not until September 2003 that the first human remains were found. They were named LB1after the cave and later turned out to belong to an extinct species of hitherto unknown and unsuspected human-like species, named Homo floresiensis. If ever there has been an unexpected anthropological and archaeological sensation, this was it.

It is still far from clear what Homo floresiensis really is, and whether and how the newly-discovered species is related to Homo sapiens or other hominids.

Prof. Teuku Jacob (1929-2007) greatly complicated matters after the discovery. Jacob, aged but still a politically influential hero of the struggle for Indonesian independence, was of the firm opinion that the Hobbits were diseased humans and of no great scientific interest. Above all, he had a problem with the media attention that the the young Indonesian discoverers and their Australian associates were receiving. See "Hobbling thre Hobbit" at the end of this chapter.

 

The location of the Liang Bua cave on Flores island where the Homo floresiensis remains were found.

The famous Kommodo Dragon National Park lies to the west of the island. The huge monitor lizards are now limited to the National Park, but when Homo floresiensis lived on the island, the dragons must have been one of the chief hazards of life there. There was another - now extinct - monitor lizard species then living on Flores which was even larger than the Kommodo Dragon.

Flores has been an island for millions of years and Homo floresiensis would have needed some kind of watercraft to make the crossing. We have no idea when the little people first entered Flores or where they came from. There must have been sea-going boats many tens or hundreds of thousands of years ago.

The discovery of Neanderthal man in the 19th century was a shock that took science and society a long time to absorb. Now we may have found an even stranger relative, if that is what the Hobbits are. The Hobbits are in some ways similar to us: they made and used stone tools, they made, used and controlled fire, they found shelter in caves, they went out to hunt and gather. But the Hobbits also differ from us and they do so much more fundamentally than Neanderthal man did.

 

Excavation

 

The Ling Bua cave excavation.

The first Homo floresiensis bones (individual LB1) was found along the wall just visible on the extreme right.

Excavation work has been going on at Liang Bua cave since 1965. Apart from stone tools, bones of stegodon, frogs, snakes, tortoises, monitor lizards, birds, rodents and bats were found. Some of the bones would have accumulated naturally on the cave floor without human or hobbitty help but some were charred which suggests the presence of fire-making humans. Forest fires would be unlikely to char material on a cave floor (ref. Morwood M.J. at al., 2004).

The skeleton was discovered when the Australian members of the team had already returned to Australia - such can be the luck of the draw in archaeology. Thomas Sutikna of the Indonesian Centre for Archaeology was responsible for the very difficult handling of the find. The remains were too young to have fossilized and the bones in the damp conditions of the cave were described as being like "mashed potatoes with the consistency of wet blotting paper". Less experienced excavators might not even have noticed the "mashed potatoes" . Securing and recovering the find was a difficult process but it was handled so well that it has inspired much justified national pride in Indonesia. (ref. Dalton R. 2004).

The great chance implicit in the relatively recent age of these bones is that they (unlike much older, fossilized remains) may still contain DNA that can be extracted and analysed. So far, however, no useable DNA has been found and it is feared that in the hot and humid climate of Flores, it may have decayed.

 

The first humanoid remains (including a skull) at the Liang Bua cave were found in sector VII (marked red in the map to the left) in September 2003 and named "Lin Bua 1" (LB1).

The askerisk in the slightly different.coloured area represents the part of the cave investigated by the earliest excavator, Verhoeven, in 1965.

Excavations on sectors I to X were carried out in 1978 and 1989 by R.P. Soejono. Starting in 2001, work was continued on sectors I, III, IV and VII by an Indonesian-Australian team that included R.P. Soejono (ref. Morwood M.J. at al., 2004).

 

 

The fateful find in sector VII:

During the excavation it soon became clear that the arms of LB1 were missing. It was assumed (correctly as it later turned out) that they would be in the unexcavated area marked with red crosses in the graphic on the left (ref. Morwood M.J. at al., 2004). In 2004 the missing arms of LB1were indeed found precisely there.

When the missing arms were finally located, there was yet another surprise: the arms were much longer, in relation to body height, than arms are among Homo sapiens. Clearly, Homo floresiensis , while human-like in many respects, was yet something new and different.

There is evidence that the skeleton was still partially fleshed when it was covered by fine sediment, which could mean that it was bruried (ref. Brown P. et al., 2004).

With the missing arms of the first Hobbit, he remains of up to eight additional Hobbits were also discovered. These were dated over widely different times but they all showed the same anatomical peculiarities that characterized the first specimen of Homo floresiensis. This discovery was the death knell for earlier speculations that Hobbits were merely diseased human individuals What was also uncovered were the remains of up to eight additional individuals, dated over widely different times but all showing the same anatomical peculiarities that characterize the first soecimen found of Homo floresiensis. This was the death knell for earlier speculations that Hobbits were merely diseased human individuals (see also "More evidence for Hobbit unearthed as diggers are refused access to cave". Nature, 437/13: 934-935).

Homo floresiensis seems to have become extinct only around 12,000 years ago which, coincidentally or not, rougly marks the transition from the Pleistocene ice age to the warmer Holocene present. The Hobbit remains at Liang Bua cave were dated to around 18,000 yearsbefore the present. At that time, Australia has had human inhabitants for at least 30,000 years and perhaps more. Hobbits and modern humans must have known of each other's existence and may well have met. This near-certainty gives an entirely new aspect to vague tales of "little people" among the modern inhabitants of Flores and elsewhere in island Indonesia. Such tales will now have be collected with a completely new sense of importance and urgency and studied with a completely new angle. It is much too early to say whether and how the two species interacted, whether they avoided contact or traded or warred. Nor we do have any idea when and under what circumstances these astonishing pygmy people have become extinct - if they did.

There is one tiny hint : the extinction of Stegodon coincided with volcanic tuffacious silts and thus may have been caused by a volcanic eruption that may also have spelt the end of Homo floresiensis.

 

Living Hobbits today?

There have long been vague and unsubstantiated stories of small people in the mountainous interiors of some of he many Indonesian islands. Nothing could be found out about them except that some seem engaged in a form of "silent trade" with the coastal population. This is a trade where one party leaves items at a traditional place and then withdraws, waiting for the other party to put something of equivalent value next to it. If the offer is not acceptable, one party would withdraws its goods or adds to it, making a new offer. Agreement was reached when one party took the other's offering away. In this way the two trading partners could exchange goods without ever meeting. It has not been possible to find out whether such trading is indeed going on in Indonesia.Indonesia outside Java is something of a black hole. At the Andaman Association we have, of course, always assumed that such unseen trading partners from the interior could be Negritos, like the Andamanese and similar groups. With the appearance of Homo floresiensis, another, utterly fantastic, possibility has appeared. Could it be... no!... never! On the other hand, why not?

In fairness, it must be said that the chances that there are Hobbits doing silent trade (or living hidden lives without any outside contact) in Indonesia or Papua-Newguinea is tiny. But it is not zero.

The one thing about Homo floresiensis that strikes all observes first and foremost is their tiny size.

A modern Homo sapiens studies her ancient and much smaller possible relative, illustrating the difference in size between the two species. Homo floresiensis had a body height of ca. 1 m and a endocranial volume of 380 cubic cm. A modern American woman has an average endocranial volume of around 1500 cm3 and a body height of 160-173 cm.

Size reduction is a predictable and well-known evolutionary trend among isolated populations on islands (see also Palau). It is a slow process that may take many thousands of years to develop among an entire population and thus indicates a long residence of Homo floresiensis on Flores (ref. Brown P. et al., 2004).

Homo floresiensis is not a "miniaturized modern Homo sapiens". Small-statured humans (African pygmies, Negrito) reach their small size through curtailed growth during puberty when the brain has already reached full size, giving a completely different ratio between brain size and stature from the unique ratio found in the Hobbits (ref. Lahr M.M. et al., 2004; Brown P. at al., 2004)). Like Homo sapiens, Homo floresiensis was an obligatory biped, i.e. their normal way to walk was on two legs just as it is among humans. The thickness and proportion of the skull, shape of the teeth, flexion evident at the skull base, are all traits of the genus Homo. Unfortunately, we do not know how they communicated with each other, i.e. whether they had language or not.

The discoverers of Homo floresiensis at first thought that their finds were dwarfed descendants of Javanese Homo erectus and part of an endemic island fauna. The species' relative brain/body size is extreme - even outside the range of the Australopithecines - and a result of their extreme miniaturization.

While it is relatively easy to say what the "Hobbits" are not, it has proven very difficult to say what they are. There is material here for decades of scientific feuding. 

Homo floresiensis differs considerably from modern human populations and from modern chimpanzees (ref. Morwood M.J. et al. 2005. "Further evidence for small-bodied hominins from the Late Pleistocene of Flores, Indonesia." Nature 437/3:1012-1017)

The shape and highly convoluted frontal lobes of a Homo floresiensis brain (below left shown superimposed on the skull) indicate advanced cognition. Not a trace of microcepahly. The Hobbits were intelligent, but to judge from the shape of the brain, it was a non-human intelligence.

The two brains on the right below show the difference in shape between the Floresian brain and a microcephalic (pathologically small-brained, cretinous) Homo sapiens. They have very little in common (ref. Balter M., 2005). Followers of the "Hobbit Cretin cult" please note.

 

 

Cretins?

When Neanderthal Man was discovered in 19th century Europe, there were not a few earnest scholars denouncing the new species as merely a group of iodine-deficient human cretins. Then as now, such a claim, if nothing else, got the claimant into the papers. That the Neanderthal "cretins" had survived for as much as 300,000 years right through the depth of the ice age and that they had spread over an area from western Siberia and the Near East to the Iberian Peninsula, all this the early researchers could not know. When the error became apparent, the cretinous idea was quietly dropped and it has not been heard from since.

But now iodine-deficiency as an argument to "explain" what appears to be a weird new species has returned and is flourishing mostly in Australia where it provides welcome publicity to otherwise obscure researchers. Some claim that the Hobbits were iodine-deficient cretins that were dumped in Liang Bua cave by their non-cretinous group members. According to tthis school of thought, the cave was a sort of prehistoric human rubbish dump.

Unfortunately, evidence on the Hobbits is lamentably limited and that has been a spur to wild theorizing. But what little evidence there is - e.g. the simple comparison between a truly microcephalic human brain and the brain of a Hobbit (see above Brain form) - suggests that the Hobbits were not microcephalic.

Additional information on allegedly microcephalic Hobbits from Falk D. at al. 2005 ("The Brain of LB1, Homo floresiensis", Nature 308:242-245 and added Added 17 April 2005:

Summary: In this article the brain of Homo floresiensis was assessed by comparing a virtual endocast from the type specimen (LB1) with endocasts from great apes, Homo erectus, Homo sapiens, a human pygmy, a human microcephalic, specimen number Sts 5 (Australopithecus africanus), and specimen number WT 17000 (Paranthropus aethiopicus). Morphometric, allometric, and shape data indicate that LB1 is not a microcephalic or pygmy. LB1 brain/body size ratio scales like that of an australopithecine, but its endocast shape resembles that of Homo erectus. LB1 has derived frontal and temporal lobes and a lunate sulcus in a derived position, which are consistent with capabilities for higher cognitive processing.

Quote: "Our data show that LB1's well-convoluted brain could not have been a miniaturized version of either Homo sapiens or Homo erectus. Nevertheless, its similarities with Homo erectus strongly suggest a phylogenetic connection, although its australopithecine-like brain/body size ratio and morphology of the femur and pelvis are not expected in a miniaturized descendant of a larger-bodied Homo erectus (which, instead, would be expected to scale allometrically along the ontogenetic curve predicted for Homo erectus). Although it is possible that Homo floresiensis represented an endemic island dwarf that, over time, became subject to to unusual allometric constraints, an alternative hypothesis is that Homo erectus and Homo floresiensis may have shared a common ancestor that was an unknown small-bodied and small-brained hominin."

Tools

A whole range of artefacts associated with Homo floresiensis were found in Liang Bua cave (ref. Morwood M.J. et al., 2004). These artefacts occurred down to a depth of 5.8 m with an oldest date of around 74,000 years. There is also a "big game" series of artefacts that appears only in connection with Stegodon (a miniature elephant) and that lasts from the oldest dated cultural horizons, between 95,000 to 74,000 years ago until its disappearance 12,000 years ago. The extinction of Stegodon coincided with volcanic tuffacious silts and thus may have been caused by a volcanic eruption that may also have spelt the end of Homo floresiensis.

It may be that the Liang Bua cave was not so much a permanent home base but an occasionally used camp for selective hunting of Stegodon.

 

Liang Bua stone tools

 

Tools found in layers dated to more than 12,000 years before the present and left at the Liang Bua cave by Homo floresiensis.

No trace of a Homo sapiens presence before 12,000 years has been found at the site (ref. Hopkin M., "The Life of a Hobbit", Nature 437/13: 935)

The island of Flores is littered with large numbers of stone tools, some possibly dating back 840,000 years. Unfortunately, most are not associated with human remains so the question of what sort of human or other creature made them cannot be answered until further finds are made that can link tools to tool-makers.

Search for the ancestor of Homo floresiensis on Java

The search for more specimens of the Homo floresiensis, first discovered in Liang Bua cave on Flores and nick-named "Hobbits," has now been extended to Song Gupuh cave on Java. Still more caves are being investigated as likely targets for excavation. The main aim now is to find the ancestors of Homo floresiensis and to establish why, where, when and how its tiny stature developed. The relationship of Homo floresiensis to Homo erectus at the moment is merely conjectural (ref. Dalton R. 2005. "Looking for the ancestors." Nature 434:432-434, 24 Mar 2005).

 

The Excavations at Song Gupuh cave on Java.

The cave would have been as attractive for early hominins as was Liang Bua on Flores. The interesting difference is that during ice ages with low sea levels, Java could be reached easily by walking across dry land. Flores, on the other hand, is surrounded by deep-sea trenches and for millions of years has been an island. The earliest Florean pre-humans must have had some way of crossing the narrow but nevertheless formidable passage.

Homo erectus is thought to have survived on Java until perhaps 50,000 years ago while on Flores what was possibly a form of Homo erectus, Homo floresiensis survived until 12,000 years ago. The search at Song Gupuh and other caves in Indonesia may answer the question (and no doubt throw up countless new ones). But no new evidence has so far been forthcoming.

The following is a brief description on some of he shenanigans surrounding the discovery of Homo floresiensis (also known as "Hobbits") on the Indonesian island of Flores and particularly of Prof. Jacob's role.

 

The Professor's Biography

by Sri Wahyuni, originally published in the Jakarta Post, 24 May 2003

Becoming a paleoanthropologist, a somewhat rare profession nowadays, had never been Teuku Jacob's childhood dream. In fact, Jacob did not find anthropology very interesting until he was a college student.

Born in Peureulak, Aceh, on 6 Dec 1929, Jacob is a professor emeritus of anthropology at Gadjah Mada University. He heads the Laboratory of Bioanthropology and Paleoanthropology at the university's School of Medicine.

Jacob came to terms with anthropology after studying anatomy while he was finishing his studies at Gadjah Mada University's School of Medicine (1950-1956). He continued his study of anthropology at the University of Arizona in Tucson, Arizona (1957-1958) and at Howard University graduate school in Washington D.C. (1958-1960), where he fell in love with the subject. "Anthropology is very important for Indonesia, especially because it is one of only few countries in the world where human skeletal remains of early man have been found," Jacob told The Jakarta Post.

His hands-on study was done at Sangiran, a famous archeological site in the Central Java town of Sragen, some 15 km north of Surakarta. He began exploration work there in May 1962. He chose Sangiran because it was the nearest archeological site from Gadjah Mada University, where he was then teaching. Another reason for the choice was more of a financial one. A financial crisis was crippling Indonesia at that time; inflation was extremely high and transportation was a dire problem.

He later found out that Sangiran, which covers an area of some 6 km by 8 km, was not only the country's widest but also Indonesia's richest archeological site. Jacob said that over 60 of an estimated 70 remains of prehistoric skeletons found in Central and East Java had been unearthed in Sangiran. The rest were discovered elsewhere in the same general area, such as Ngandong, Sambungmacan and Trinil. Apart from the finds, his team has also discovered hundreds of ancient stone tools and thousands of animal fossils over the last 40 years of excavations.

Before Jacob began his excavation projects in Sangiran, other researchers had found the fossilized remains of 20 individuals but no stone tools had ever been found. "What we have found proves that Sangiran is the biggest archeological site ever found in the country," said Jacob, who received his doctoral degree in paleoanthropology from the Rijksuniversiteit Utrecht in the Netherlands in 1968.

The United Nations Educational, Scientific, and Cultural Organization (UNESCO) in 1996 named Sangiran a world heritage site, essential to the understanding of human evolution.

During the early years of his excavation activities in Sangiran, Jacob usually went to the site once a week, with the university jeep. Sometimes he would spend up to two months on the site from the beginning to the end of a particular dig.At present, however, he only occasionally returns, usually to select a particular spot for further exploration or to see a new discovery."I let the younger people do the physical activities now," said Jacob, who has written more than 20 books on anthropology, culture, medical subjects and countless articles.

The biggest Sangiran excavation project took place in 1964 for almost nine weeks. The most important finding was the discovery of a skull he code-named "Sangiran 10" in 1963. In 1973, he discovered a new archeological site in Sambungmacan village."My heartbeat quickened upon realizing that we found the first cheek bone of a prehistoric man in the country," Jacob said, adding that it was, in fact, in Sambungmacan that many remains had been found.

The study of prehistoric people, according to Jacob, is very interesting although many tend to consider this particular science a limited field of study. "That's not true. The study on prehistoric people covers a wide range of subjects, such as their lifestyle, economy, environment, demography and so forth," he said.

Jacob insists that people need to learn about the history of their origin, their ancestors so as to project their future. What people are facing at present is nothing but the result of the past and it will develop in the future. Only by studying about the past will people become more civilized.

"No one can see exactly what will happen in the future, but we can make a better future by doing good things now," the lecturer said.

"Working in this particular field of study is just like playing detective. We investigate, looking for the missing parts, reconstructing something based on what we have in our hands, and try to reveal what might be behind all the findings. In a criminal investigation a piece of hair can help solve a complicated murder case. In paleoanthropology, similarly, a piece of bone can reveal many things."

On 15 Aug, Jacob received the Bintang Mahaputra Nararya award from the government in recognition of his outstanding contribution to the country's cultural promotion.

In 1993, he received a gold medal from the Indian Boards of Alternative Medicine. He was also a recipient of the 1984 Researchers Award from the of Indonesian Medical Association (IDI) and in 1983 he received Paul Broca Medal from French Center for Scientific Research on anthropology.

His important discoveries of fossils include, Homo erectus, Homo erectus palaeojavanicus, Homo sapiens (Sangiran archeological site), Homo erectus soloensis (Ngandong and Sambungmacan), Homo sapien (Trinil and Tamiang).

 

Discovery of the Hobbits

The discovery of an extinct dwarf people (also popularly known as "Hobbits") on Flores island, Indonesia in September 2003 was one of the most surprising finds in recent palaeoanthropology. For details see

Some of the events surrounding early efforts to suppress this story would be funny if they had not been so serious and concerning such an important find. One can only be grateful that a new generation of well-trained plaeoanthropologists is taking over in Indonesia, one of the world's most important treasure houses of mankind's common past and heritage.

Here, however, we are concerned with the story of what happened before and after after the first Hobbit remains had been found.

The main actor in those tale story was then retired Prof. Teuku Jacob (1929-2007)). He had trained as a medical doctor and became a hero of the Indonesian war of liberation against the Dutch and Japanese occupations before, during and after World War 2. After the war the young Jacobs received degrees in anthropology in the US and in the Netherlands. From the 1970s onwards, his laboratory at Gaja Mada University in Yogyakarta on Java was the centre of Indonesian palaeoanthropological studies. Teuku Jacob is undoubtedly a man of enormous courage and strong patriotic sentiments - making it all the more surprising that he has repeatedly acted in a way seemingly designed to cause maximum damage to his science and to his beloved country's international scientific reputation.

As Peter Brown, one of the Indonesian-Australian team that discovered Homo floresiensis, notes:

Professor Jacob, I think, has a history of keeping fossil materials to himself, collecting materials, retain them in his collection and making it difficult for anybody else to have access to them. Professor Jacob was not part of the excavation team, not part of the research team, not part of the publication team, and not part of either of the institutions involved in the cross-institutional agreement. He had no connection at all, which makes him going and collecting the material and removing them extremely bizarre.

 

Not discovered by Prof. Jacobs? Must be forgeries!

Teuku Jacob, without having seen the fossils and without involvement in their discovery (which almost certainly was at the bottom of his furious hatred for the Hobbits) from his retirement pronounced the first individual Hobbit found to be "microcephalic" (abnormally small-headed, a diseased cretin). Later more individual Hobbits were found in the same cave site, all apparently similarly disadvantaged. ccording to Jacob, an entire race of diseased dwarves populated Flores more than 12,000 years ago.

Prof. Jacob has been called "an extremely proud individual, extremely sensitive to hints of colonialism" (ref. Dalton R. 2005. "Looking for the ancestors." Nature 434:432-434). This proud individual has had a firm grip (some would call it a stranglehold) on Indonesian palaeoanthropology for decades. There is nothing wrong with being proud of being Indonesian nor in having a firm grip on a subject - except that Jacobs was such a firm adherent of the "multiple-origin" theory of human origins that he has not only refused to consider evidence contradicting his cherished theory, he actively obstructed research by withholding (and even destroying) evidence that did not fit in with his opinions.

In protecting his favourite theories, Jacobs tended to go to extremes. For example: in Swisher C.C. et al. 2000. Java Man, University of Chicago Press, he has received an unusual entry in the index: "Jacobs T., obstructive behaviour of, 86-89".

 

... and Forgeries must be destroyed

In November 2004 retired Prof. Teuku Jacob, without asking anyone's permission, took the partly-fossilized bones from their repository in Jakarta to his laboratory in Yogyakarta, 440 km away.

What followed was a standoff that set an older generation of paleontologists against a younger generation with the government caught in the middle. Jacob was then considered Indonesia's most prominent paleontologist, a role which added status in a country that traditionally reveres age, seniority and status. On the other side was a team of younger scientists based at the Indonesian Center for Archaeology who were partly funded by the Australian Research Council.

Jacob handed over the (badly damaged) remains only after an internationally embarrassed Indonesian government put severe pressure on him to do so. The damage done while the Homo floresiensis bones were in Jacob's care was considerable. The man must have thrown a major fit before finally obeying orders.

Apart from from four leg bones that remained in Jacob's custody, all the fossils were returned on 23 Feb 2005. Apart from the damage shown above, the discovery team then found that the returned items were also severely damaged by rubber molds made at Jacob's lab:

  • Much of the detail at the base of the skull was pulled off.
  • The left outer eye socket and two teeth were broken off and glued back. Bits of molded rubber still adhere to some sections
  • Long, deep cuts mark the lower edge of the hobbit's jaw on both sides, left by a blade used to cut away molded rubber.
  • The chin of a second hobbit jaw was snapped off, losing bone. It was glued back together misaligned and at an incorrect angle.
  • The pelvis was smashed, perhaps in transit, destroying details that reveal body shape, gait and evolutionary history.

The story did not even quite end there:

"We have a big dispute with Professor Jacob," said Tony Djubiantono, chief of the archaeology center and co-leader of the team. "We didn't give him permission to do any of these things."

Paleoanthropologist Harry Widianto of the Yogyakarta Archaeology Agency was sent to get the bones from Jacob in Yogyakarta. When he got them to his own lab before shipping them to Jakarta, Widianto says, "We opened the packages and saw the mandibles (jaws) were damaged."

In a phone conversation with USA TODAY, Jacob said he would respond to the charges by e-mail. In his e-mail, he acknowledges that molds were made in his lab to create display casts but denies that the bones were damaged there. "If some breakage took place on any bone, it must be during the transport in Yogyakarta or from Yogyakarta to Jakarta," Jacob says. "Both mandibles were intact until the last minute in our lab, as proven by photographs taken on the last days." Jacob never responded to a request for the photos.

Prof. Jacobs died on 17 October 2007.

 

In fairness we will let Professor Jacob have the last word on the matter:

Conflict from Flores: Storm in a Teacup

by Teuku Jacob 

In the last two months, the international media had been clamouring over Flores man, acclaimed as a new species and considered as the most important human fossil discovery in the last 50 years.

The news had been so spectacular, for it was announced in Nature, a prominent scientific journal based in London. Newspaper, radio, and television journalists pounced at the announcement and added sensational bits to the story. For the sake of publicity the Australian scientists disregard their government's travel warning.

The discovery comes from archaeological excavations in the limestone cave of Liang Bua ('Cold Cave') in west Flores by a joint Indonesian--Australian team from the Indonesian Centre of Archaeological Research and the University of New England, under the coordination of Prof. Soejono and Dr. Morwood. The former is a senior Indonesian prehistorical archaeologist and the latter is an Australian expert of prehistoric cave paintings. The fossils (subfossils) were studied directly by Australian physical anthropologist Dr. Brown and indirectly by English palaeoanthropologist Dr. Stringer, from data sent by Brown.

Their conclusion from one studied specimen is to propose a new species, "Homo floresiensis", which had close affinities with Homo habilis of 3--4Ma (mega-annum, millions of years) which lived in East Africa. In the proposed evolutionary tree, "H. floresiensis" is the direct descendant of H. habilis and underwent evolutionary insular dwarfing, hence its small head, half the size of the chimpanzee brain, and small stature of 1 metre. It is capable of making stone tools in the form of flakes and blades. There are several designations for its antiquity (13Ka, 18Ka, 36Ka, and 95Ka; Ka=kilo-annum, thousands of years), obtained by several dating methods. A lot of experts doubt the reliability of the OSL method.

Therefore it is no surprise that palaeoanthropologists, archaeologists, anatomists, anthropologists and Quarternary geologists were shocked. Creationists, those who were against the theory of evolution and holding on to their literal interpretation of the Bible (Protestant creationists) and the Quran (Islamic creationists) used the opportunity to launch an attack to the evolutionists, whom they consider to interpret the finding by their own whim.

The emerging scepticism is not without reason. There are seven skeletons discovered (probably more, since there are other unprepared bones in the matrix), but the discoverers had only studied one of them to make their conclusions. The LB1 skeleton was designated as the holotype, the hypodigm over which the paradigm stands. Why was it compared against H. habilis specimens that is so far separated from it in time and space? Why not compare it with other findings from Liang Toge, Liang Momer, or Liang Panas (other cave sites in Flores)? Is evolution reversible: can the brain get smaller, and then larger again?

Does the similarities with Homo erectus imply a close affinity with the mentioned species? Is it not a case of microencephaly (small brain) causing the forehead to be not filled? The pentagonal shape of the skull implies a small cerebellum; is this not caused by an underdevelopment of the cerebral skin and cerebellar parts?

Is micrognathy (reduction of jaw) not the cause of the unreduced dentition and the unprotruding lower part of the mandible? The dentition clearly shows that the specimen belongs to Homo sapiens, with features such as agenesis (unrooted), rotation and close-packing of the teeth, whilst archaic features are not shown.

The Laboratory of Bio- and Palaeoanthropology at Universitas Gajah Mada has worked together with the Indonesian Centre of Archaeological Research since the 1960s. Palaeoanthropological materials were usually sent to Yogyakarta and archaeological finds sent to Jakarta. The cooperation went well all the time without any disturbance. Later a radiometry laboratory was built in Bandung. Skeletons from archaeological digs sent to Yogyakarta comes from all over the islands, from Sumatera to Irian.

The Yogyakarta lab focuses on Middle Pleistocene human fossils although there are some older and younger material. We kept almost a third of all H. erectus fossils in the world, and many people earned their degrees studying them here. However, not many Indonesians are interested because this field is outcompeted by faster tracks to materialistic success.

Researchers from the Yogyakarta lab has not actually been involved with the Liang Bua excavation. The author had once done some research on fossil humans from Flores caves stored in the Netherlands, which are the discoveries of Pater Verhoeven at the 1950s, and colleagues from the Yogyakarta lab once studied specimens from Liang Bua, excavated by Dr. Soejono from 1978 to 1989. The involvement of the Yogya lab with the 2003--2004 Liang Bua discoveries began when before Ramadan of 1424 H Prof Soejono asked for the team to study the LB1 skull. I was ill and bedridden at that time, but from the photo shown the skull appeared like an infrahuman primate; however it was still partly encased in its matrix and not photographed by anthropological standards. In July this year, Prof Soejono approached us again, asking to collect the discoveries, and the head of the Centre of Archaeological Research would provide funds for transport. I agree that younger and hard-won researchers should get the opportunity to study the new findings, instead of leaving it to foreign researchers.

There is some irony when an Australian expert, whom Prof. Soejono had only known for several years, asked him whether the author, whom Prof. Soejono had known for 40 years, is can be trusted. That chap needs to look into the mirror because the Yogya lab has been deceived three times.

Australian journalists report that the Australian researchers were unhappy with the fossils being taken to Yogyakarta. Their counterparts also dislike the idea of the study being based in Yogyakarta. Foreign journalists, especially Australian, were informed, and I was barraged by cynical, naïve, and conspiracy-accusing questions concerning the acquisition of the bones: whether it will be returned, will it be worth studying, would other people be allowed to see it, whether I was the only person disagreeing with its designation as a new species, why it is not studied in Jakarta, whether this is a turf war between scientists, and others. It should be noted that there are also many knowledgeable and objective people among the foreign journalists.

Some of the questions show their shallow understanding of the field. Some does not understand the difference between archaeology and palaeoanthropology. Others thought that palaeoanthropological studies do not need supporting material as facilities for reconstruction and comparative material such as ape and modern human skeletons, fossils, relevant literature, and others.

Threats and intimdation, even bribery and pressure will not make our Yogyakarta team budge. Research funding does not entitle that the donors may put their noses into the internal affairs of a country. There is no 'deputy sheriff' of archaeology for South East Asia that can push people around. I know that archaeological digs are prohibited in Australia because the native Australians consider their ancestors' graves as sacred, and many early findings had been reburied (I once was asked for help concerning this matter), therefore Australian archaeologists (which is continually produced) are forced to wander off to South East Asia (which is rich in ancient artefacts) and the south Pacific; so the turf war, if there is any such thing, is actually a turf conquest by latter-day conquistadors.

If not for the long-term good relationship with the Centre of Archaeological Research, the Yogya team is content with our H. erectus fossil collection. Many foreign students had studied at the Yogya laboratorium before; therefore the accusation that our collection is off-limits is very upsetting.

Since the fossils are now being studied it is obvious that it cannot be anywhere else; it should not be passed around. The loan is for research purposes and I respects the terms, which also specifies that it cannot be displayed at will. Important fossils are not normally shown off to every passing tourist; even research postgraduate students need recommendation from their professors to gain access. Important collections need curators that know how to take care of fossils and who should be allowed to study them. Those foreign journalists might want to try and ask if they can see and get their hands on human fossils stored in Western institutions.

To get a balanced view, we should not just read Australian papers but inquire other sources. I received many phone calls, facsimiles, e-mails from around the world, including some from Australia which agrees with my opinion.

There is one Australian who wanted to force us to return all archaeological human remains back to the Centre for Archaeological Research. These are quite a large lot, because it would include collections dating back to 1963. and they took a lot of space. See how he tries to pressurize us, claiming that he would get the Australian government involved.

About the Liang Bua bones, our preliminary conclusions are as follows. Maybe two of them were actual insular dwarfs, as the dwarf Stegodon timorensis. At least one suffers from primary microcephaly, with microcrany, microencephaly, and micrognathy, which caused mental retardation, a disruption in brain growth especially on the forehead and cerebellum, giving a passing resemblance to H. erectus and H. ergaster skulls.

The cranial capacity seems to be larger than what had been announced; we also obtained a larger height estimate than 106cm. I presume the Liang Bua fossils are related to the Liang Toge skull, which was considered a proto-Negrito by Verhoeven (although I do not agree with Verhoeven's designation).

Establishing a new taxon is not easy. New species must be proposed on the basis that it is a different morphological and biological complex from other taxa, therefore implying reproductive isolation. Paleopathology remains an open option; other factors such as geochronology, archaeostratigraphy, and palaeodemography should also be considered.

In closing, do not consider the discovery of the dwarf Flores man as irrelevant. There are microcephalic fossils from thousands and hundreds of years ago discovered in Europe and South America.

The whole story of the Liang Bua findings had been blown out of proportion, creating a storm in a teacup. Prof. Tjia from Kuala Lumpur sent me a fax that said:

I (and Mrs.) support Pak Jacob's actions. At least it will keep some of the "cultural adventurers" comments in check. Many among them are just eager to make "surprises"--whether correct or not--and they often consider local experts as incapable... Our people should be in control of the material...,"


Kompas in November quoted Prof. Moendarjito, Prof. Sedyawati, and Drs Arief Rahman the head of UNESCO Indonesia, as being concerned that the Flores findings will be "transported to Australia".
