Evolution Timescales

The long periods over which evolutionary processes such as mutation, selection, and drift act, ranging from thousands to billions of years.

Natural Selection

The process by which organisms that are better adapted to their environment tend to survive and produce more offspring, a key mechanism of evolution.

Beak Size

The physical measurement of the length or depth of a bird's beak, which can influence its ability to feed and mate.
