Overview

Evolution is the idea that the nature of a species can change irreversibly (evolve) over time – a fact which can be directly observed over human timescales, especially in lower life-forms such as bacteria.

The word "evolution" is often used to refer to the scientific theory of evolution by natural selection.

notes

We probabaly need to check our terms here. Does evolution include speciation, or is that a separate concept? Has speciation been observed in human timescales? Does any form of anti-Darwinism actually claim that there isn't evolutionary change within a species over time? -W.
