What is Comparative Anatomy?

Back

Comparative Anatomy is the study of the similarities and differences in the anatomy of different species. It helps scientists understand evolutionary relationships.

What is a blowhole in whales?

Back

A blowhole is a specialized nostril located on the top of a whale's head, allowing it to breathe while swimming.

What is an example of homologous structures?

Back

Homologous structures are body parts that are similar in different species due to shared ancestry, such as the flipper of a dolphin and the arm of a human.

What do all embryos have early in development?

Back

All embryos have tails early in development, which is a common feature among many vertebrates.

Front

What are fossils?

Back

Fossils are the preserved remains or traces of organisms from the past, providing evidence of historical life on Earth.

Who is a developmental biologist?

Back

A developmental biologist is a scientist who studies the process of development in organisms and works to understand and prevent birth defects.

Front

What is the significance of studying comparative anatomy?

Back

Studying comparative anatomy helps scientists understand how different species adapt to their environments and how they are related through evolution.

Front

What is an example of a vestigial structure?

Back

A vestigial structure is a body part that has lost its original function through evolution, such as the human appendix.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures are similar due to shared ancestry, while analogous structures are similar due to convergent evolution, not ancestry.

Front

What role do fossils play in understanding evolution?

Back

Fossils provide evidence of how species have changed over time and help scientists reconstruct the evolutionary history of life.
