  27. Describe the saying “survival of the fittest”

  28. Describe the saying “survival of the fittest” • Animals with stronger traits have a easier time getting food, mates, and shelter. In turn they get to live longer and reproduce more. The “strong” traits get passed down while “weak” traits eventually fade away.
