This makes perfect sense, since the Bushmen in native Africa have the genetic markers of everyone in the world.
I'm not sure that this is true. It might be, but I haven't heard about it before.
Now, genetics certainly provides evidence for a long history for the human species. The population in Africa is very, very genetically diverse, while populations outside of Africa are much more genetically homogenous, just as we would expect if
Homo sapiens lived in Africa for much of its history, and then a very few small groups moved out of Africa and eventually colonizing the rest of the world.

The migratory lines are clear.
Indeed! And
important genetic markers are fantastic evidence for this!
