Evolution acts to expand the diets of animals to buffer thespecies against changes in food supply that might lead toextinction.

The first individuals to eat slugs must have survived better onaverage than those that lacked this ability in the earlypopulations in British Columbia.

Every slug-eating snake had higher reproductive success than allthe slug-rejecting snakes, generation after generation, until therewere no more slug-rejecters in British Columbia.

None of the above
