While away on holiday (gloat!) I got the opportunity for uninterrupted listening to podcasts 🙂 One of these was a July episode of the Skeptics Guide to the Universe, which included a discussion of the (in)famous Kennewick Man remains. These 9,000-years-old bones have been the focus of considerable controversy in the US, where they were claimed by Native American tribe as being an ancestor’s bones & so not available for scientific study. However, this belief was overruled in 2004 by a US Court of Appeals Judge, allowing scientists to continue studying the surprisingly complete skeleton.
Unfortunately, that study has had to focus on anatomy: an attempt to obtain and amplify DNA from the bones concluded that
No DNA suitable for PCR amplification could be extracted from the Kennewick samples studied. Thus, no conclusion regarding its ethnic ancestry or cultural affiliation based on DNA can be made.
While some sequences were found, these matched DNA from individuals involved in the analysis & so were most likely modern contamination. This means that data from – among other things – analyses of cranial and facial morphology have been used to try to determine the likely origins of Kennewick Man. As the fearless investigative team at Riddled, Inc. report, these analyses have been used to justify some rather shaky conclusions, including a rather tenuous link to New Zealand. One cannot better the Riddled team’s take on this one 🙂
