Developmental homology.

Front

What is the term for evolution that occurs over a short period of time?

Back

Punctuated Equilibrium.

How do fossil records demonstrate common ancestry?

Back

They show the relation between the structures of two species.

Front

What is the primary cause of differences in organisms?

Back

Evolution.

Front

What is anatomical homology?

Back

The comparison of body structures in different species to find similarities that indicate common ancestry.

Front

What is molecular homology?

Back

The comparison of DNA and protein sequences between different species to find similarities that indicate common ancestry.

Front

What is gradualism in the context of evolution?

Back

The theory that evolution occurs slowly and steadily over long periods of time.

Front

What is the significance of vestigial structures in evolutionary biology?

Back

They are remnants of organs or structures that had a function in an early ancestor, indicating common ancestry.

Front

What role do mutations play in evolution?

Back

Mutations introduce genetic variation, which can lead to new traits that may be advantageous for survival.
