"It is really not worth looking at, but I couldn't stop laughing, so I have to point it out....Many conceivable maps of human migrations can be made based on the genetic and climatological evidence currently available. The map-animated virtual global journey at the Bradshaw Foundation Journey of Mankind : The Peopling of the World is one admirable attempt - at least from the graphics side - to provide such a map.
This is what we get when there is not enough critical science of human dispersals. We're not seeing history here, we're making it up."
However, the graphics are where the fun ends - and the erroneous content begins, especially because of all the overstretched and unsupported climatological - and other - hypotheses....
Especially disturbing in terms of the available evidence is the idea that mankind first moved up the Nile Valley out of Africa - and then allegedly became extinct. A new subsequent group of humans - luckily kept in reserve in Africa in the interim - then allegedly reached Asia and Europe via the Arabian peninsula in a topographically navigational miracle and from there spread throughout the globe. A very unlikely scenario.
For a much more likely version of human migrations, see the National Geographic Genographic Project. And even there, great caution is advised. Too many details still need to be unraveled.
