    The Sahara used to be far greener in the not too distant past I thought? Also the taiga will be very far less green very soon.

      The area around a major river being greener helps in no way the emergence of a river civilization.

      What matters is that the river banks are fertile, the area has a good climate (especially a long growing season), domesticates were brought, and the area around is worse for sustenance.

      Much to the contrary, the area around being better for sustenance probably makes it more difficult and unlikely for a civilization to emerge, as it allows people to freely escape taxation / corvée by just migrating away from such attempts.

        That area has supported hominids since way before civilization. Its crazy how many “cousins” we used to have. It seems like biodiversity used to be way higher there.

            Yeah but it does explain why humans were able to evolve in that area, and then eventually adapted to its changes better than the branches that didn’t make it.
