1) Species have great fertility. They make more offspring than can grow to adulthood.

2) Populations remain roughly the same size, with modest fluctuations.

3) Food resources are limited, but are relatively constant most of the time.

4) In sexually reproducing species, generally no two individuals are identical. Variation is rampant.

5) Much of this variation is heritable.
