numerous sites across the Persian Gulf where we can actually see remnants of these ancient populations.

It's a very difficult question to answer because we don't have any DNA.

But the most likely path is the Sinai up to the Levant where Neanderthal lived for a very long time, moved into Europe.

And we know there's strong evidence now that most likely the first interaction between or the first cross between

between Neanderthal and Homo sapiens.

The interbreeding happened in the Levant and perhaps happened more than once.

So we know for a fact that they existed together at some point in the Levant.

Now, how did the Neanderthal got there?

Yes, I mean, you can argue that they may have also, you know, come through the Bab al-Mandab.

You have to realize that through Bab al-Mandab in Yemen, they could cross it.

You don't need to.

I mean, the water was so shallow there, so people could cross.

And the Sinai was very different back then.

I mean, you know, you can actually cross it much easier than today.

It was not all that desert like today.

And again, as we learn more about how people move, this one out of Africa migration is no longer sustainable.

I think, you know, and one thing I have to also mention is we don't talk about migration.

Back migration also played a huge role.

People moved out of Africa, but a lot of people moved back into Africa.

And so a lot of movement happened over the last 50,000 years.
