Observation 1: Individuals within populations vary
in their inherited traits.
Observation 2: Offspring are produced in greater
numbers than can survive in the environment and
many die before reproducing
Inference 1: Individuals whose inherited traits are
advantageous in a particular environment are
more likely to survive to reproduce.
Inference 2: Over many generations, the unequal
survival and reproduction of individuals with traits
advantageous to the environment will result in an
accumulation of those traits in the population.
