Definitions:

Community

An association of populations of different species living together in a defined habitat with some degree of interdependence. Compare with ecosystem.

Sexual Reproduction

A type of reproduction in which two gametes (usually, but not necessarily, contributed by two different parents) fuse to form a zygote. Compare with asexual reproduction.

Genetic Variation

The diversity in gene frequencies within a population, resulting from mutation, sexual reproduction, and other genetic processes, contributing to the population's adaptability.

Evolution

Any cumulative genetic changes in a population from generation to generation. Evolution leads to differences in populations and explains the origin of all the organisms that exist today or have ever existed.
