A microstratigraphic study of the Hobbit cave, Liang Bua, reveals the use of fire between 41,000 and 24,000 years ago. The dates suggest that Homo sapiens used the cave after Homo floresiensis and fueling speculation that modern humans were responsible for the extinction of the hobbits.

Humans did wipe out real-life ‘hobbits’, say scientists
The Independent, 1 July 2016

Liang Bua, a karstic cave located on the island of Flores in eastern Indonesia, is best known for yielding the holotype of the diminutive hominin Homo floresiensis from Late Pleistocene sediments. Modern human remains have also been recovered from the Holocene deposits, and abundant archaeological and faunal remains occur throughout the sequence. The cave, the catchment in which it is located and the gross aggradational phases of the sediment sequence have all been subject to a great deal of scientific scrutiny since the discovery of the holotype of H. floresiensis in 2003. A recent program of geoarchaeological research has extended analyses of the site’s deposits to the microstratigraphic (micromorphological) level. The stratigraphic sequence in the cave is well defined but complex, comprising interstratified sediments of diverse lithologies and polygenetic origins, including volcanic tephras, fine-grained colluvium, coarse autogenic limestone gravels, speleothems and anthropogenic sediments, such as combustion features. The sedimentological and chemical heterogeneity suggest that processes of site formation and diagenesis varied markedly through time, both laterally and vertically. We present initial results from samples collected in 2014 from an excavation area near the rear of the cave, which yielded radiocarbon ages from charcoal that fill an important temporal gap in the chrono-stratigraphic sequence of previously excavated areas of the site. The results indicate marked changes in site environment and hominin activity during the Late Pleistocene, relating primarily to the degree to which the cave was connected to the hydrogeological system and to the varying intensities of use of the cave by hominins. Importantly, we identify anthropogenic signs of fire-use at the site between 41 and 24 thousand years ago, most likely related to the presence of modern humans.

News of the week: Yet another Hobbit tale

No Comments

This week’s been abuzz with another Hobbit story again, this time saying that the diminutive bones belong to malnourished humans rather than a new species. The paper, written by two Australian researchers in the Proceedings of the Royal Society, B: Biological Sciences, posits a new theory that the hobbits were sufferers of dwarf cretinism.

Are the small human-like fossils found on Flores human endemic cretins?
Peter J. Obendorf, Charles E. Oxnard, Ben J. Kefford

Fossils from Liang Bua (LB) on Flores, Indonesia, including a nearly complete skeleton (LB1) dated to 18kyr BP, were assigned to a new species, Homo floresiensis. We hypothesize that these individuals are myxoedematous endemic (ME) cretins, part of an inland population of (mostly unaffected) Homo sapiens. ME cretins are born without a functioning thyroid; their congenital hypothyroidism leads to severe dwarfism and reduced brain size, but less severe mental retardation and motor disability than neurological endemic cretins. We show that the fossils display many signs of congenital hypothyroidism, including enlarged pituitary fossa, and that distinctive primitive features of LB1 such as the double rooted lower premolar and the primitive wrist morphology are consistent with the hypothesis. We find that the null hypothesis (that LB1 is not a cretin) is rejected by the pituitary fossa size of LB1, and by multivariate analyses of cranial measures. We show that critical environmental factors were potentially present on Flores, how remains of cretins but not of unaffected individuals could be preserved in caves, and that extant oral traditions may provide a record of cretinism.

Perak Man is Back in Town

Guest blogger LIZ PRICE from cavesofmalaysia kindly gives us her review of the Perak Man exhibition now on at the Muzium Negara in Kuala Lumpur.

Perak Man is Back in Town

Malaysia’s oldest inhabitant, Perak Man is back in KL. There is a special exhibition dedicated to him at Muzium Negara as part of the “Festival Kuala Lumpur 2006″. Perak Man is an 11,000 year old human skeleton which was found in Gua Gunung Runtuh in Lenggong, Perak in May 1990. It is the only complete late Paleolithic skeleton to have been found and is an important piece of Malaysia’s prehistory.

The month long exhibition is designed to be informative in an entertaining way and it certainly works. As you enter the building which is constructed to represent the mouth of the Gua Gunung Runtuh, you are greeted by an animated talking skeleton.

Walking around takes you through a dark passage past a series of exhibits and tableaux depicting scenes from 10,000 years ago. The first one shows Perak Man on his death bed, surrounded by friends or relatives. Research shows he died from a severe tooth infection. At first I was a bit amused to see the skeletons move, and some had flashing red eyes. It’s great for the kids though.

Perak Man suffered from a rare congenital deformity but living amongst a close knit community meant he had people to care for him when he could no longer hunt or look after himself. Although he was only in his 40’s when he died, that was probably a good age for that era.

Perak Man has been dated at 10-11,000 years old. However evidence of human activity in the Lenggong Valley has been revealed dating back more than 100,000 years. This area could well have been the capital of Malaysia in those days.

The next scene shows the burial rites. It is suggested that Perak Man was an important member of his tribe as his burial was performed ceremonially. He was buried in a fetal position, with legs folded up to the chest, the right hand bent up towards the shoulder and the left hand on the abdomen. The body was placed in a 1 metre deep shallow grave running east to west, and perpendicular to the cave entrance.

For the researchers from Universiti Sains Malaysia, led by Prof. Dato Zuraina Majid, it was a dream come true that the Paleolithic burial was done so meticulously and was so well preserved. The skeleton was almost complete, except for some missing bones such as toes, ribs and parts of the face. Offerings of food such as meat and riverine shells were with the body, as well as 10 different types of tools. The tools could have been Perak Man’s own collection. As a final touch, 2878 shells were placed on and around the body.

There is a slide show in Bahasa Malaysia giving a brief outline of the discovery and showing the types of food eaten in those days. Perak Man and his relatives lived by subsistence activities, which means they were hunter gatherers. They hunted wild animals like wild boar, deer, mousedeer, leopard, monkeys, iguanas and tortoise. To supplement the meat diet they gathered plants and riverine shells for food and medicine. They used stone tools for their daily activities. Pebble tools were used for heavy duty work such as chopping trees, splitting bones and snipping the tips off shells. Flake tools were used to cut and scrape meat, and to sharpen wood and bone to make new tools. There is a display of stone tools and models of how they were used.

Further along is a selection of push button displays, but unfortunately the buttons were not working. The next section is devoted to research. There was analysis on the faunal remains, which gives some information on the animals eaten, the hunting skills, as well as the climate and environment. The bones and teeth were also studied. Perak Man went to Japan from 7 September to 24 November 1996. A display case houses a replica of Perak Man’s skeleton, the original is housed at the Lenggong Museum.

As you turn the corner you are invited to insert a card into a slot. Nothing happened then there was a rumbling sound and suddenly a motorbike driven by 2 modern skeletons drives towards you, with a background scene of modern KL. I’ve never seen so many mechanical talking skeletons outside of a fairground!

The last section houses half a dozen computers on which you can answer 20 questions relating to Perak man. The computers, as well all the film clips are only in Bahasa Malaysia, so the exhibition seems to be designed more for locals than for foreigners. Finally there is a feature on a new book “Perak Man and Other Prehistoric Skeletons of Malaysia”, edited by Zuraina Majid. The book is available for sale.

This exhibition is great for anyone interested in Malaysia’s prehistory and is guaranteed to grab the attention of kids with the animated skeletons and detailed tableaux. It is due to finish on 31st July but almost certainly will be extended until at least August 16th.
