Tree for 54 Present-Day Humans, Ten Ancient Modern Humans, and Seven Archaic Humans
The phylogeny in the top panel was constructed using Maximum Parsimony and rooted using midpoint rooting. The branches for present-day humans do not all end at the same point, giving a sense of the inherent uncertainty in time measurements based on mtDNA due to its limited sequence span. However, the consistent shortening of the branches of ancient humans relative to their closest present-day human relatives is apparent in the figure. This is the basis for our clock calibration. Pre- and post-Neolithic ancient samples are indicated as red and blue circles, respectively, and colored squares indicate the geographical origin of 54 present-day humans that we coanalyzed with them. Date estimates for major divergence events are shown at the nodes. In the bottom panel we show a map giving geographical origin of the samples.
