Re: Another Blow To Steady Evolution of Intelligence
I don't know where you're coming from, but it's no news flash to those who study human evolution that pre-humans exhibited unchanging behaviour for ages at a time with brian size and behaviour altering in bursts. Once we hit Homo Sapiens Sapiens, cultural and tool making traditions changed rapidly compared to the past. For example, our bro' the Neandertals kept the exact same tool making style for well over 10exp5 years.
