Front

What is Artificial Selection?

Back

Front

What is an evolutionary common ancestor?

Back

An ancestral species that is shared by multiple modern-day species.

Front

A theory of biological evolution developed by Charles Darwin, emphasizing natural selection.

Front

What evidence supports the theory of evolution?

Back

Fossils, genetic similarities, and observed changes in species over time.

Front

What is a common misconception about evolution?

Back

That evolution occurs in individual organisms rather than populations over generations.
