Homologous, Analogous, Vestigial

Front

What are homologous structures?

Back

Structures that are similar in different species because they were inherited from a common ancestor.

Front

How do homologous and analogous structures differ?

Back

Homologous structures have similar anatomy but different functions, while analogous structures have different anatomy but similar functions.

Front

What are vestigial structures?

Back

By comparing anatomical structures that have a similar position.

Front

What is an example of homologous structures?

Back

The forelimbs of humans, whales, and bats.

Front

What is an example of analogous structures?

Back

The wings of insects and birds.

Front

What is the significance of vestigial structures in evolution?

Back

They provide evidence of an organism's evolutionary past.

Front

What is convergent evolution?

Back

The process where different species develop similar traits due to similar environmental pressures.

Front

What is divergent evolution?

Back

The process where related species become more dissimilar over time.

Front

What role do homologous structures play in creating an evolutionary tree?

Back

They provide evidence of common ancestry.
