Which of the following situations best shows Darwin’s theory of natural selection as a mechanism for evolution?
A. The long neck of a giraffe is the result of its ancestor continually reaching for higher branches.
B. The ancestor of the snake had its legs bitten off by a predator, thus all of its offspring had no legs.
C. A long, thin-beaked bird can reach nectar in a flower that other birds cannot, so it survives and breeds offspring that also have long, thin beaks.
D. During its lifetime, a man works out and gets increasingly large muscles. Thus, all of his offspring will be born with strong muscles as well.
