According to Lahn, "The making of the large human brain is not just the neurological equivalent of making a large antler. Rather, it required a level of selection that's unprecedented..."
Extra fast and fortuitous random mutations effecting human brain development due to environmental pressure? Hmmm… Lahn says, “We've done a rough calculation that the evolution of the human brain probably involves hundreds if not thousands of mutations in perhaps hundreds or thousands of genes — and even that is a conservative estimate. But Lahn also says, “It is nothing short of spectacular that so many mutations in so many genes were acquired during the mere 20-25 million years of time in the evolutionary lineage leading to humans…”
Now consider that the last hypothetical common primate ancestor of both humans and the modern ape family lived approx 6 million years ago and had a brain size of 350 cc (approx brain size of a chimp). In regard to the human brain though, its not just size that matters (see antlers) or we would be studying whale and dolphin brain development… or maybe they would be studying us…
