The Sahara wasn't always a desert. Back then it was green and lush and full of food. A branch of humanity did go up the Nile and into Canaan 125,000 years ago. My previous research had led me to believe mtDNA haplogroups M and N took separate routes, but now I'm seeing both of those groups came from the Arabian migration according to the genetics.
