The predecessors of at present’s cattle were undoubtedly selectively managed in hunts in natural habitats (similar to our weak artificial selection) earlier than individuals had been taken into captivity and bred . Animals that bred well could then be selected (both consciously or unconsciously) for favorable traits (corresponding to our robust artificial selection).
