The out of Africa theory was debunked in the 90s. Neil Degrassmoker Tyson is a dumb ex jock, not a scientist. He got a job at an observatory because he was an athlete and 2 board members got it for him. Then when networks wanted a new face of science on TV they didn't want a geek in a bowtie so they picked an ex jock.
I hate science and I've forgotten more than he ever knew.
