Ancient DNA: Would the Real Neandertal Please Stand up? Alan Cooper, Alexei J. Drummond, Eske Willerslev Current Biology Volume 14, Issue 11, Pages R431-R433 (June 2004) DOI: 10.1016/j.cub.2004.05.037
Figure 1 An example genealogy and table of exclusion probabilities. Coalescent theory indicates that all mtDNA lineages from modern humans (black) can be traced back to four to seven ancestral sequences around 20,000–30,000 years ago. In contrast, the five inferred fossil human sequences (green) are likely to still be distinct lineages 5,000 years earlier, at the assumed time of mixing. The maximum Neandertal genetic contribution (%) that can be excluded is given for differing numbers of non-Neandertal lineages (both fossil and inferred modern sequences) observed at the time of mixing (from [10]).
