Most hominin species, including Homo sapiens, arose in Africa. It is sometimes possible to extract DNA from ancient humans (of our species and closet cousins) for analysis. The oldest hominin DNA ever sequenced came from a 400,000-year-old thighbone. Comparisons among ancient remains and population of humans around the world have yielded insights into when and how various Homo species migrated out of Africa. The diagram below shows a comparison of DNA sequence from different human groups. position 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 Dinka G C G C Italian G - тст G Khoisan G T G T G - T G - A - - TG C - - T P.N.

If phenotype is a proxy for genotype, then why do you think that paleoanthropologists erroneously designated Neandertalensis as a separate species prior to the accessibility of DNA analysis?  What were they comparing them to when they were lumping or splitting fossils taxonomically and why would these reference populations provide the bias resulting in such a confounding factor in their assessments?
