Front

What is biogeography?

Back

The study of the distribution of species and ecosystems in geographic space and through geological time.

Front

What are adaptations?

Back

Changes in species that allow them to survive changes in the environment.

Front

Body parts that have lost their original function through evolution.

Front

What is an example of a transitional form in evolution?

Back

Aetiocetus, which has nostrils located at the middle of the skull.

Front

What is the significance of Pangaea in biogeography?

Back

Pangaea was a supercontinent that broke apart, leading to the distribution of species like marsupials across different continents.

Front

What are homologous structures?

Back

Body parts in different species that share a common ancestry, even if they have different functions.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures share a common ancestry, while analogous structures serve similar functions but do not share a common ancestry.

Front

What role do adaptations play in evolution?

Back

Adaptations help species survive and reproduce in changing environments.

Front

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

Back
