Color me skeptical -- particularly as to the 400,000 BC date. There just weren't no people back then.

Well, you certainly can’t argue with the evidence you produced.

See the listing for Neandertalis? Click back a tad and you'll find Heidelbergensis. He's not talked about as much because they aren't found so often.

There were OTHERS just recently discovered.

Here's the deal, there've been 21 major glacial periods over the last couple of million years. They are divided up into about 100,000 years of cold and 10,000 years of warmth called Interglacials.

Sometimes there are periods of less than 10,000 years warmth and they are called interstadials.

Human beings are smart. They move North when it's warm and South when it's cold. The result is that humanity gets adapted and readapted over and over and over in broad cycles.

Sometimes groups get left behind and they do a different sort of adaptation. The result is the constant creation and recreation of "the people", until, at last, here we are, prepared to enter the crucible again.

Your chart makes it look like there was no genus homo between erectus and modern man. There seems to be a gap.
