Sheep Nature
Posted on Monday, July 5th, 2010 at 8:12 pmWhy nature didn't gave canine teeth to the sheep ?
and make them aggressive
that would increase their chances to survive.
Ummm, because they aren't carnivores and have no need of canines.
Teeth have evolved in a manner to best suit the feeding habits of a given organism. As a prey species, and herbivore, sheep born with canines would have been under great selective pressure (i.e. they would not be able to feed as well as sheep with no canines). Thus, sheep with no canines would be favoured by evolution because they were better able to secure nutrition. There just wasn't enough of a selective advantage for sheep with canines to prosper over sheep without.
Hope it helps!
