HUMAN ORIGINS RESEARCH BY BELIZE SCIENTISTS

 DIFFERENT KINDS OF HUMANS HAVE PROBABLY INHABITED EARTH FOR AT LEAST 14 MILLION YEARS.  QUITE A LOT OF EVIDENCE GOING BACK TO 90,000 YEARS.  THIS IS A DISCUSSION ON A BELIZE LISTSERVE FOR TECHNICAL AND SCIENTIFIC THINGS.


Hugh,
The interesting follow-on question is whether the differences between our 3 main modern racial grouping can be attributed to the interbreeding (or absence thereof) between Neanderthals & Cro-Magnon, and between Denisovans and Cro-Magnon, to produce three varieties of modern humans.

Political Correctness, of course, says not.
