The Toba Catastrophe

What I find is wild is Stephen J. Gould's idea that evolution is like a battlefield: long periods of boredom followed by periods of panic and action. Just 75,000 years ago, homo sapien's breeding pool was knocked down to 1,000 to 10,000 people. This created a genetic bottleneck. Also, all of the race's came from diversification after this event. More interesting: some of the pre-cursor species (H. ergaster, H. erectus, and possibly H. floresiensis., etc.) could have existed upto this time. If the Toba Catastrophe happened just 75,000 years ago, that's really recent. It underlines that evolution is fluid and it can flow fast. With the current environmental stresses, we could be entering into an evolutionary bloom of new species (or die off of the unviable-- I'm looking at your, Mr. Tibetan Suicide Monkey). My inner geek thinks about the BSG idea of reducing a population to very few survivors. Or the Lord of the Rings idea that Middle Earth existed in our far past. Or...
