Front

What are analogous structures?

Back

Structures in different species that serve similar functions but do not share a common ancestry.

Front

What is the significance of pelvic bones in whales?

Back

They are vestigial structures, indicating evolutionary history and adaptation.

Front

What is the role of competition in evolution?

Back

Competition for resources can drive natural selection, influencing which traits are favored.

Front

What is adaptation?

Back

A trait that enhances an organism's ability to survive and reproduce in its environment.
