Up till now we thought of cultural developments leading to the opportunity of people to move out of Africa. Now we see, I think, that it was the environment that was the key to this and the change from a glacial period into an interglacial opened the other possibility to leave Africa though the southern corridor and this certainly not only happened once, this happened many times during the (quarternerly) and this leaves a lot of possibilities for human migrations and keeping this in mind, might change our view completely. There are not many exits from Africa. You can only exit by the Sinai or by the south. That’s the only – that’s the only points where you can leave it. so either it’s the route that we propose, or it could be the route from Egypt to Sinai and both are possible, both have their problems and in any case, our findings open a second way, which in my opinion is more plausible for massive movements than the northern route.
