Darwin

Front

Charles Darwin’s observation that finches of different species on the Galápagos Islands have many similar physical characteristics supports the hypothesis that these finches:

descended from a common ancestor.

Why are advantageous traits more likely to be passed onto offspring?

Back

Because they are more likely to survive and reproduce.

Mutations are important because they bring about:
