Back

Embryology studies the development of embryos, showing similarities in early stages of different species, suggesting common ancestry.

Front

What is adaptation?

Back

Adaptation is a trait that helps an organism survive and reproduce in its environment.

Front

What is the role of mutation in evolution?

Back

Mutations are changes in DNA that can lead to new traits, providing raw material for evolution.

Front

What is artificial selection?

Back

Artificial selection is the process by which humans breed plants and animals for specific traits.
