Yup. Millions of years can do that!
Something is wrong here. War, disease, death, destruction, hunger, filth, poverty, torture, crime, corruption, and the Ice Capades. Something is definitely wrong. This is not good work. If this is the best God can do, I am not impressed.

Re: New Dactyl
RS, the Sahara has been in flux for much longer than that. 6 or 7kya is just the most recent pluvial period for the Sahara.

No, dannan, the Sahara hasn't been green since.dannan14 wrote:RS, the Sahara has been in flux for much longer than that.
Re: New Dactyl
RS, you must've misread my reply. i agreed with you that the last time the Sahara was green was 6 or 7kya, but it wasn't green for millions of years straight up until 6kya.

Are you saying the Sahara was only green for one or two millennia in the past X million years?dannan14 wrote:RS, you must've misread my reply. i agreed with you that the last time the Sahara was green was 6 or 7kya, but it wasn't green for millions of years straight up until 6kya.
Re: New Dactyl
No, i'm saying the amount of rainfall in the Sahara has been oscillating for many millennia. When it gets wet, people and other animals move in. As it dries out, they get pushed to the periphery again. Check out Brian Fagan's "The Long Summer: How Climate Changed Civilization". Lots of great stuff in there and an interesting read.
