Outline the evidence for evolution provided by the fossil record, selective breeding of domesticated animals and homologous structures.

5.4.3

State that populations tend to produce more offspring than the environment can support.

5.4.4

Explain that the consequence of the potential overproduction of offspring is a struggle for survival.

5.4.5

State that the members of a species show variation.

5.4.6

Explain how sexual reproduction promotes variation in a species.
