I can't help but notice that the geography, supposed paths, and times, don't seem to make any sense.
Why is this? Because there will have been multiple migrations of any given "clan", and each may or may not have followed a similar path.
I'd expect a much more diffuse patterning, which need not necessarily be "simply connected". (ie: two non-adjacent clans may overlap, without either having any association with any intermediate clans.)
For the graphs to be as "neat" as portrayed, each clan must have had ONE core migration, along ONE route, with NO splitting off at any point.
Further, any pre-existing hominids in those regions must have -entirely- been replaced. Merged wouldn't be good enough, as there'd be a 50/50 chance of the female line being the existing hominid.
(Such pre-existing hominids are known to have existed. There were probably hundreds of seperate explorations away from Africa. The skeleton known as "Lucy", for example, is from one such exploration that has since gone extinct, but was not related to either the early human line, OR the Neathaneral line.)
Because of the pre-existing tribes, and because of the high probability that early humans merged with, rather than always extinguished, every such tribe they encountered, the results sound bogus.
Let's play with numbers for a moment. Let's say that, of the hundreds of attempts to leave Africa, only 10 "clans" were viable, including Neathanderal and human. Let's say that, of every clan, there were only 10 females (at most) at any given time. That =STILL= gives you 100 possible DNA strands, and 100! possible geographical mappings.
Errr... That's a lot of combinations, folks! And that's just creating numbers at random. The actual figures are probably an order of magnitude higher. To get 7 patterns for the WHOLE of Europe, and 33 for the WHOLE globe is simply too small! WAAAY too small.
