Comparative Anatomy

Front

What are analogous structures?

Back

Body parts that serve similar functions but have different origins and structures.

Front

What do homologous, analogous, and vestigial structures indicate in evolution?

Back

They provide evidence for the relationships between ancient species and current ones.

Front

What is an example of a homologous structure?

Back

The forelimbs of humans, bats, whales, and cats.

Front

How do homologous structures differ from analogous structures?

Back

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

Front

Why do vestigial structures provide evidence of evolutionary history?

Back

They indicate organisms have evolved from ancestors with different needs and lifestyles.

Front

What are homologous structures?

Back

Structures in different species that are similar due to shared ancestry.

Front

What are vestigial structures?

Back

Remnants of organs that are no longer useful in the current form of an organism.

Front

What is the significance of studying comparative anatomy?

Back

It helps scientists understand evolutionary relationships and the adaptation of species.

Front

Can you give an example of analogous structures?

Back

The wings of birds and insects.

Front

What does the presence of vestigial structures suggest about an organism's evolution?

Back

It suggests that the organism has evolved from ancestors with different functions for those structures.
