A Missing Link from Kent's Cavern in Devonshire

A prehistoric maxilla (upper jawbone) fragment was discovered in the cavern during a 1927 excavation by the Torquay Natural History Society, and named Kents Cavern 4. The specimen is on display at the Torquay Museum.

Although previous radiocarbon dating suggested the bone was about 35,000 years old, a new study in Nature redates it securely to 44.2-41.5 kyr. The article by Tom Higham et al., "The Earliest Evidence for Anatomically Modern Humans in Northwestern Europe," also claims that on the basis of dental comparisons it is "human" rather than "Neanderthal."

The Kent's Cavern fragment "therefore represents the oldest known anatomically modern human fossil in northwestern Europe, fills a key gap between the earliest dated Aurignacian remains and the earliest human skeletal remains, and demonstrates the wide and rapid dispersal of early modern humans across Europe more than 40 kyr ago."

A related article in the same issue of Nature is "Early Dispersal of Modern Humans in Europe and Implications for Neanderthal Behavior," by Stefano Benazzi et al. It attempts to place the so-called Cavallo fossil from southern Italy in a timeframe of about 44,000 years ago, thus suggesting a "rapid dispersal of modern humans across the continent before the Aurignacian and the disappearance of Neanderthals."

Neither study considers that the evidence they are examining may be the result of hybridization between "humans" and "Neanderthals." Like most geneticists the authors have rigid categories and do not consider that our definitions of species and sub-species and transitions in technocomplexes and traits are in flux as new discoveries are made.

One man's Mede may be another man's Persian, and we note that the "fossil race" is not devoid of scientific jingoism pitting one country's news-making finds against another's. So far England seems to be winning.

However, the British still have to live down Piltdown Man, a fraud of biblical proportions that fooled the world for almost half a century until the 1950s. The Piltdown hoax is perhaps the most famous paleontological hoax ever. It has been prominent for two reasons: the attention paid to the issue of human evolution, and the length of time that elapsed from its discovery to its full exposure as a forgery combining the lower jawbone of an orangutan with the skull of a fully developed modern human.

The editors sum up the two new studies by writing, "The reanalysis of findings from two archaeological sites calls for a reassessment of when modern humans settled in Europe, and of Neanderthal cultural achievements." We wish that the paleontological community would think more out of the box and reassess how, when and where "humans" and "Neanderthals" interbred.
