It is not often that naturists complain to the BBC about people wearing clothes in one of their programmes. However, this has happened in the UK recently, after the broadcasting of scenes featuring early humans in the series "Andrew Marr's History of The World". A spokesperson said: "It is astonishing that the BBC, that once proud bastion of journalistic integrity, should be sacrificing its reputation for commercial reasons." According to the Daily Telegraph's report, "The group said that in the Exodus from Africa, Ancient Egypt, the Minoans, the Caribs, the Australian aborigines, and members of a contemporary South American tribe, the costumes were the product of the BBC censors, not history." Instead of contesting the complainants, a representative from BBC Audience Services, said he was sorry about the "compromises in accuracy". Apparently, the corporation felt "obliged" to make compromises in the production of dramatic reconstructions. "You are of course correct in pointing out that, in reality, natives in various scenes in the early part of the series would have been naked," he said. "But in making a series like this we have to take into account the sensitivities of the widest possible world audience." The throwaway phrase "of course" is worthy of critical scrutiny. We need to ask whether these comments accurately represent the findings of science. How much do we actually know about the sartorial habits of prehistoric man?
Bone tools from Cave Bay Cave, Tasmania. "These early tools raise the question of what needles were used for. The Tasmanians found by the first visitors in the 16th and later centuries went virtually naked and are not known to have had needles. It is possible (but unproven) that 22,000 years ago, at the depth of the ice age, they did have some form of clothing which they discarded when the climate warmed after 12,000 years before the present."

Scientific evidences are really quite modest. We have evidence that Cro-Magnon Man sewed skins together and protected themselves against the cold. Some figurine artefacts suggest clothing. An analysis of the DNA of clothing lice has been used to estimate a date when it originated from head louse ancestors (although this is an indirect avenue of research). An analysis of energy use by Neanderthals in Northern Europe during the mild Eem interglacial period has concluded that they needed well-fitting clothing and footwear to survive (another indirect approach to addressing the issue). We have a situation where there are few constraints for theoretical models. In such cases, presuppositions tend to take over and "just-so" stories tend to be constructed in the name of science (e.g. "how ape-like ancestors lost their body hairÂ£ and "how clothing was first invented"). We need to recognise such explanations as expressions of preconceived ideas about human history and refrain from treating them as scientific conclusions.
One characteristic of research into prehistoric man is that the more we uncover evidence of cultural traits, the more we find the hallmarks of modernity. This is contrary to expectations if evolutionary presuppositions are on the right lines. Some recent papers illustrate this point and are briefly reviewed here.
First, the artistic abilities of Palaeolithic Man.
Several Hungarian researchers have examined prehistoric and modern artwork ranging from cave paintings of cows and elephants to statues and paintings of horses, elephants and other quadrupeds in motion. Their goal was to see how well these artistic depictions matched scientific observations of animal motion. They found that the majority of depictions of these animals walking or trotting had their legs incorrectly positioned, but the prehistoric paintings had the lowest error rates of 46.2%, whereas art prior to 1880 depicted animal motion incorrectly 83.5% of the time. This error rate decreased to 57.9% after 1887. (Source here, commentary here) The cavemen artists were keen observers of the natural world and had the technical and aesthetic skills to portay animals accurately in their paintings.
Second, the ability of Neanderthal Man to self-medicate.
Although Neanderthals have generally been portrayed as hunter/gatherers, their diet has been understood to be primarily carnivorous. However, plant eating was practised and this is where new research has come up with surprises. The researchers examined material entrapped in dental calculus from five Neanderthal individuals from the northern Spain. The abstract has this summary: "Our results provide the first molecular evidence for inhalation of wood-fire smoke and bitumen or oil shale and ingestion of a range of cooked plant foods. We also offer the first evidence for the use of medicinal plants by a Neanderthal individual. The varied use of plants that we have identified suggests that the Neanderthal occupants of El Sidron had a sophisticated knowledge of their natural surroundings which included the ability to select and use certain plants." (Source here) In the discussion, they make it clear that this evidence gives Neanderthals a remarkably modern profile:
"We propose that that the Neanderthal occupants of El Sidron, whose hypothesized, cannibalized remains were discarded at the site, had a sophisticated knowledge of their natural surroundings, and were able to recognize both the nutritional and the medicinal value of certain plants."
Third, Homo heidelbergensis artefacts provide evidence of the use of hafting technology.
It is known that both Neanderthals and early Homo sapiens made spears with hafted stone tips. It is said that this technology becomes relatively common after about 300,000 years ago. The skills for making the spear tips from stone and then attaching them to the shaft are by no means trivial. However, new research has presented "multiple lines of evidence implying that stone points from the site of Kathu Pan 1 in South Africa were hafted to form spears around 500,000 years ago. The points' damaged edges and marks at their base are consistent with the idea that these points were hafted spear tips." (Source here).
The significance of these finds is that the authors must predate those groups of humans that are known to have possessed hafting technology:
"it appears that the common ancestor of Neandertals and Homo sapiens, commonly thought to be Homo heidelbergensis, was the first to develop hafting technology. "It now looks like some of the traits that we associate with modern humans and our nearest relatives can be traced further back in our lineage"."
Fourth, evidence of cooking by Homo erectus.
Earlier this year, a team of archaeologists excavated ash of "burnt grass, leaves, brush and bone fragments in sediments 30 metres inside the Wonderwerk Cave in the Northern Cape province". The original occupants of the cave have not been clearly identified, but "the team believes it was probably Homo erectus." The ash has been inspected for signs of being washed into the cave, but the fragments appear to be in situ. This find is not unique - as other ash deposits from horizons associated with H. erectus have suggested fire for cooking. However, the Wonderwerk Cave site is the first where lightning strikes can be ruled out. Previously, many archaeologists doubted that H. erectus could ever use fire for cooking.
So, research continues to challenge the past consensus about cultural evolution. One wonders when this will lead to a new paradigm in palaeoanthropology. But for the present, we have many traditional attitudes claiming to find support from science. The naturist complaints about the lack of nakedness in portrayals of prehistoric man is just one example. So let us look a little closer at the examples they provide: "the Exodus from Africa, Ancient Egypt, the Minoans, the Caribs, the Australian aborigines, and members of a contemporary South American tribe". Of these groups, all are fully modern and had clothed ancestors. Evidences of nakedness go hand in hand with evidences for the loss of other "technologies" by people-groups. Since their migrations were in pre-historical times, there is no information about whether they were clothed or naked when they migrated. What about the "the Exodus from Africa"? This is the "out-of-Africa" theory of the origins of modern man. It is of interest that the clothing lice research has relevance to this issue, because the authors find an association between the origin of modern man and the origin of clothing lice. "Our analysis suggests that the use of clothing likely originated with anatomically modern humans in Africa and reinforces a broad trend of modern human developments in Africa during the Middle to Late Pleistocene." Therefore, a case can be made for the clothing lice departing from Africa along with the humans. Thus, even this example does not support the claims of the naturists.
And earlier in time, can anything be said? The authors of the clothes mite paper write: "Whether archaic hominins used clothing cannot be assessed from these lice and may require the collection of lice from archaic human remains, which is unlikely." Such caution is the nature of science. Nevertheless, we can remind ourselves that advances in knowledge about ancient humans show them to be culturally more advanced than has been predicted by the Darwinian evolutionists. We can have some confidence that this trend will continue and evidences of modernity will continue to be found.
