Hi Sterling - Once more the voice of quiet reason. The madmen in the room always seem to find me, whether its Zubrinite Mars nuts, cultists, nu-agers, or simply less than secure anthropologists. Hell, I even mentioned erectus in the footnotes, but did they care? No. The taxonomy was a mess, and I said so. I was a space journalist reeling from a stroke, and not a physical anthropologist.
Now has anybody (hint, hint) apologized yet for their remarks? No. A 1,100,000 Hiroshima impact and 1.8 billion tons of vaporized rock will have effects. Like splitting a hominid group into two parts, which then follow different evolutionary paths. The death range must have exceeded 100-200 miles. And all of the game animals (food) and useful plants and trees would have been killed as well. The impact explains the plains. And still no one is looking at the Malaysian impact and the early sapien fossils from there. Ed --- On Sat, 12/5/09, Sterling K. Webb <sterling_k_w...@sbcglobal.net> wrote: > From: Sterling K.
