Homologous, Analogous, Vestigial

Front

What are homologous structures?

Back

Physical features shared by different species that indicate a common ancestry.

Front

What are analogous structures?

Back

Organs or features in different species that have a similar function but evolved separately.

Front

What are vestigial structures?

Back

Parts of an organism that are no longer needed for survival.

Front

What is the main purpose of vestigial structures?

Back

To serve as historical remnants of structures that had a function in ancestors.

Front

How do homologous structures support the theory of evolution?

Back

They indicate a common ancestry among different species.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures share a common ancestry, while analogous structures serve similar functions but evolved separately.

Front

Why are vestigial structures important in studying evolution?
