Cattle losing adaptations to environment

Researchers have uncovered evidence showing that cattle are losing important environmental adaptations, losses the researchers attribute to a lack of genetic information available to farmers. After examining genetic material stretching back to the 1960s, they identified specific DNA variations associated with adaptations that could one day be used to create DNA tests for cattle -- tests that could tell farmers whether their cattle are suited for one environment or another.
