Eric, you are speculating about the harvest of full-curl rams resulting in less fit individuals. There is no evidence of a reduction in horn length or age of rams shot by hunters in Alaska since 1972.

Scientists have tried to find some link between hunting and reduction in the size of horns or antlers. It’s more complicated than you might think. The sheep with the largest horns isn’t necessarily the biggest or smartest ram in the band. And there is certainly evidence that the ram who exerts his dominance over other rams doesn’t do all the breeding. When you claim that hunting full-curl rams is “taking the best out of the herd” you are forgetting the ewes, who also contribute to a lamb’s survival, some would say more than the ram, which lost interest shortly after mating. Focusing on only the macho rams is a little sexist.
