All these images of primitive people looking like they all have black hair. So, did fair skinned, blonds and red heads just magically appear? suddenly?

@HighlyCompelling : Thanks for reiterating that.

@smd5001 : I question the reasoning behind that. The evolution of the synthesis of the hormone "vitamin" D has issues assuming melatonin density started out high. Which in turn presumes direct sun exposure and blue skies. The prehistoric Earth probably lived under a continuous, moisture laden haze, and therefore grabbing as much UV B radiation as possible required lighter skin, to convert 7-dehydrocholesterol into pre-D3 which then isomerizes into D3. The assumption of catastrophists is the haze was not primeval but resulted from an impact and volcanoes and whatnot, and the period of development of light skin became selected. I'm afraid not enough time of the catastrophic weather event allowed such a scenario. At least I find it hard imagining it.
