Back

The forelimbs of humans, whales, and bats.

Front

What is an example of an analogous structure?

Front

What is the significance of studying comparative anatomy?

Back

It helps scientists understand evolutionary relationships between different species.

Front

What are the main types of structures studied in comparative anatomy?

Back

Homologous structures, analogous structures, and vestigial structures.

How can comparative anatomy provide evidence for evolution?

Back

By showing similarities and differences in structures among different species, it indicates common ancestry.
