Adaption

This is an inherited characteristic that increases an organism's chance of survival.

Adaptive Radiation

This describes the evolution of many diverse species adapted to their specific habitats but having one common ancestor. This usually occurs when the original species is separated from each other completely, such as geographic isolation. When this occurs, the organisms adapt to different resources, leading to a new species.

Analogous Structures

These are structures which are similar in different organisms because they evolved in a similar environment, yet do not have a common ancestor.

Biodiveristy

Number and variety of living organisms; includes genetic, species, and ecological types.
