Back

The maximum population size that an environment can sustain.

Front

Define 'natural selection'.

What is 'gene flow'?

Back

The transfer of genetic variation from one population to another.

Front

Explain the 'founder effect'.

Back

A decrease in genetic diversity that occurs when a small group of individuals establishes a new population.

Front

What is the significance of the fossil record in understanding evolution?

Back

It provides evidence of gradual changes in species over time.

Front

Define 'carrying capacity'.

Back
