Bones show they hunted wild goats, sheep and pigs, male bias in slaughter of pigs goats, and sheep, and young pigs slaughtered predominantly, pig bones are intermediate in size between wild ad domestic. Indicators of domestication indicator of pig domestication is a reduction in molar length (like with dogs) and reduced snout- caused by neotenization of skull morphology. Early changes in skull morphology may be the result of an extended (cid:862)getti(cid:374)g to k(cid:374)o(cid:449) you(cid:863) self selectio(cid:374) phase of a co(cid:373)(cid:373)e(cid:374)sal path(cid:449)ay i(cid:374)to domestication. Earliest definitive evidence of pig domestication; 2000 yr. record show pig bones changing from wild to domestic. Genetics evidence points to multiple independent domestication events across the broad range.
