Front

What is biogeography?

Back

The study of the distribution of species and ecosystems on Earth.

Front

Which evidence of evolution focuses on the study of DNA and proteins?

Back

Molecular biology.

Front

What are analogous structures?

Back

Structures that have similar functions but different evolutionary origins, like bat wings and butterfly wings.

Front

What is a common ancestor?

Back

An ancestral species from which different species have evolved.

Front

What are homologous structures?

Back

Similar structures found in different species that share a common ancestor.

Front

What is the significance of fossil evidence in evolution?

Back

Fossils provide a record of past life forms and show how species have changed over time.

Front

What is natural selection?

Back

The process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is genetic variation?

Back

Differences in DNA among individuals, which can lead to different traits.

Front

What is the role of mutations in evolution?

Back

Mutations are changes in DNA that can create new traits, contributing to evolution.

Front

What is the difference between convergent and divergent evolution?

Back

Convergent evolution occurs when unrelated species develop similar traits, while divergent evolution occurs when related species become more different.
