Species evolve over time through natural selection.

Each individual species was specially created and could never change.

Individuals compete for survival and the fittest survive.

Earth’s surface changes rapidly due to catastrophic events.

They do not vary.

They compete for survival and some are more fit than others.

They are all equally fit.

They change only due to acquired traits.

Earth’s surface formed by many small, gradual changes over long time (uniformitarianism).

Populations can outgrow environments, leading to deaths.

Acquired traits can be inherited (later disproven).

Co-discovered natural selection; published at same time as Darwin.
