Evidence of Evolution

Front

What is evidence of evolution?

Back

Evidence of evolution refers to the various types of data and observations that support the theory of evolution, including fossil records, genetic similarities, and anatomical structures.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, even if they have different functions.

Front

What are vestigial structures?

Back

Vestigial structures are remnants of organs or structures that had a function in an early ancestor but are no longer functional in the current organism.

Front

What is embryology in the context of evolution?

Back

Embryology is the study of embryos and their development, which can provide evidence of evolutionary relationships among species.

Front

What does a common ancestor mean?

Back

A common ancestor is an ancestral species from which two or more different species have evolved.

Front

How can DNA comparisons provide evidence of evolution?

Back

Comparing DNA sequences among different species can reveal genetic similarities and differences, indicating how closely related they are and suggesting a common ancestry.

Front

What is the significance of the fossil record?

Back

The fossil record provides chronological evidence of past life forms and their evolution over time, showing how species have changed.

Front

What is natural selection?

Back

Natural selection is 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 due to similar environments, while divergent evolution occurs when related species become more different over time.

Front

What is adaptive radiation?

Back

Adaptive radiation is the process by which a single ancestral species rapidly diversifies into a wide variety of forms to adapt to different environments.
