Geneticist Spencer Wells has really bowled over the scientific community
with
the conclusions of his new research. After testing the blood of
thousands of men
around the world for the DNA sequence in their y-chromosomes, he's uncovered
some startling facts. Apparently there are 2 subspecies of our species,
a tropical
one and a temperate one. The tropical subspecies is represented by
sub-Saharan
Africans, Melanesians, Australian Aborignes, and some Dravidians. The
temperate
subspecies includes all the rest of the world peoples, descended from
one man
who lived in Kazakhstan about 40,000 years ago.
