"The data presented on the domestic pig add to an emerging picture of
independent domestication of distinct populations of the wild
ancestors of major domestic species. In cattle, a considerable
genetic divergence between European/African (Bos taurus taurus) and
Asian (Bos taurus indicus) cattle has been documented on the basis of
both mtDNA and nuclear DNA sequences (LOFTUS et al. 1994 ; MACHUGH et
al. 1997 ). The presence of distinct European and Asian mtDNA clades
in domestic sheep has also been reported (HIENDLEDER et al. 1998 ).
The considerable genetic diversity detected in these species has
been interpreted :
1. to largely reflect genetic divergence prior to domestication.
2. In contrast, ancient domestication (>100,000 YBP) was invoked to
explain the pattern of genetic diversity in the control region of
mtDNA among dogs (VILA et al. 1997 ).

==================================================================
For the 'new Darwin' : As you can see there are Other 'Idiots' (to
quote your 'clever' thoughts) that think that 'ancient domestication'
(>100,000 YBP) is the cause of these splits .
----------------------------------------------------------------
So if your never hear about such things doesn't mean that these
are 'idiot toughts' only because they are so new for you...
==================================================================
"The average genetic distance between the European and Asian clades
of mtDNA cytB sequences was estimated at 1.5%, which is about three
times higher than the 0.5% observed between the most divergent human
mtDNA haplotypes (HORAI et al. 1995 ). The sequence divergence
between the alleles at the three nuclear genes included in this study
is also several times higher than that generally observed in humans
(CHAKRAVARTI 1999 ). These differences in pattern of genetic
diversity are consistent with a strikingly different population
history of humans and domestic animals. Humans appear to have
expanded enormously from a rather small population present 100,000
YBP (HARPENDING et al. 1998 ). At that time, the wild boar was
abundant and widespread in Eurasia. The independent domestication of
European and Asian wild boars followed by introgression provided a
broad genetic basis for the domestic pig.
