Evidence of Evolution

Front

What are analogous structures?

Back

Structures that are similar in appearance but not in structure, indicating convergent evolution.

Front

What does the similarity in bone arrangements among different organisms suggest?

Back

It supports the hypothesis that these organisms share a common ancestor.

Front

What can be inferred if two organisms have similar DNA traits?

Back

They probably share a common ancestor.

Front

In geological layers, which layer is typically considered the youngest?

Back

The topmost layer.

Front

What is a vestigial structure?

Back

A structure that is no longer needed for survival, such as the human appendix.

Front

What is the significance of homologous structures in evolution?

Back

They indicate a common ancestry among different species.

Front

How do fossils provide evidence for evolution?

Back

Fossils show changes in species over time and can demonstrate transitional forms.

Front

What is the role of embryology in understanding evolution?

Back

Similarities in embryonic development among different species suggest a common ancestor.

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 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.
