Comparative Anatomy

What is a vestigial structure?

Back

A vestigial structure is a remnant of an organ or structure that was functional in ancestral species but is no longer useful in the current organism.

Front

Can you give an example of a vestigial structure in humans?

Back

The human appendix is an example of a vestigial structure.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, even if they have different functions.

Front

Provide an example of homologous structures.

Back

The forelimbs of humans, bats, whales, and cats are examples of homologous structures.

Front

What are analogous structures?

Back

Analogous structures are features in different species that serve similar functions but do not share a common ancestry.

Front

What do analogous structures suggest about evolution?

Back

Analogous structures suggest that organisms independently evolved similar solutions to adapt to environmental challenges.

Front

Why is comparative anatomy important in the study of evolution?

Back

Comparative anatomy helps uncover relationships between ancient and current species, providing insights into evolutionary processes.

Front

What is the significance of studying vestigial structures?

Back

Studying vestigial structures can provide evidence of evolutionary change and the history of species.

Front

How do homologous structures support the theory of evolution?

Back

Homologous structures support the theory of evolution by demonstrating how different species can evolve from a common ancestor while adapting to different environments.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures arise from a common ancestor and may have different functions, while analogous structures arise independently and serve similar functions.
