Within the population of finches on the galapagos islands, exists within beak size. during wet years, small tender seeds flourish and beaks have a selective advantage.

I would say that the answers are: 'large variation' and 'smaller'. A population of finches with a large variation in genotype, and therefore phenotype, for beak size would allow the population to adapt to changing food availability. The increase in small seeds within their environment would provide a selective advantage to individuals with smaller beaks, as they would be more deft at handling the seeds.

My pigs teeth have already came in years ago, with my first molars, and my second molars are pretty much in. my wisdom teeth will be unable to come in, but i'm getting those out on monday.
