The History of Evolutionary Thought: What is a species?
The philosophies of Plato and Aristotle influenced early Christian beliefs.
Evidence supporting evolution was discovered even before Darwin's time.
Charles Darwin's voyage on the beagle sowed the seeds for his theory of evolution.
Darwin and Wallace both proposed that evolution occurs by natural selection.
Evolutionary theory arises from scientific observations and conclusions based on them.

The Evidence for Evolution
The fossil record provides evidence of evolutionary change over time.
Comparative anatomy provides structural evidence for evolution.
Embryological stages of animals can provide evidence for common ancestry.
Modern biochemical and genetic analyses reveal relatedness among diverse organisms.
Artificial selection demonstrates that organisms may be modified by controlled breeding.
Evolution by natural selection occurs today.
