Before the Dawn was excellent, but I do have an issue with the date approximation of 50K years for the single successful exodus out of Africa. Having read other works discussing the exodus and genetic history of our race, I cannot match 50K as the date. Ocean lowstands not withstanding, there is genetic evidence for presence of modern humans in the wider world (India for example) at the time of the Toba eruption 74K years ago. Interested to hear what others more educated in paleogenetics/paleoanthropology than myself have to say about 50K vs 85K years for the African exodus. This comment pre-supposes that responders have an acceptance of evolution. Please no religious rhetoric!
Thank you for your reply. I also read Mr Wade,s The Faith Instinct which found very interesting. I actually do have personal faith in God but do not see a conflict between science/evolution and faith. I am not a spiritual seeker My last sentence about religious rhetoric was to dissuade creationists from preaching at me with happens, and is frankly annoying in a scientific discussion. Mr Wade seems quite firm regarding the 50k year figure while much evidence suggests approx 85k year Language, hyoid bone, Neandthal interaction fit his 50k figure (vast time differences between the first two and the third)but the genetic bottleneck around Toba and sea stands do not. This is a big difference and in scientific discussion is significant hence my question
I found all kinds of different dates for the various genetic events and adaptations from the various writers in this vein. The general trend seems to push most dates farther back. I've seen language placed as far back as 125,000 ybp. Neanderthal entry into Europe farther back than that. I for one really liked the Mount Toba Eruption as the population bottleneck that culled out those without religion. Most who've written on the subject say no. The one thing that totally escapes me is how anyone can estimate the number of survivors through the ups and downs throughout our last 100,000 years. And what are "sea stands?"
