Evolution
(the review)
1. A population of snails live on grey colored rocks at
the beach. The variation of shell color ranges from
very light to very dark. Dark and light colored shells
are easily seen and caught by seagulls. Over time,
there are fewer light and dark colored snails and most
of the population is grey. This is an example of which
type of selection?
