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.

What does it mean if two organisms have very similar DNA sequences?

Back

It indicates that the organisms are closely related and share a common ancestor.

What is homology in the context of evolution?

Back

Homology refers to similarities in structure or function in different species that arise from a common ancestor.

What is analogy in evolutionary biology?

Back

Analogy refers to similarities in function or appearance between species that do not share a common ancestor, often due to convergent evolution.

Front

What is a vestigial structure?

Back

A vestigial structure is a body part that has lost its original function through the course of evolution, such as the human appendix.

What is the significance of the fossil record in understanding evolution?

Back

The fossil record provides chronological evidence of past life forms and shows how species have changed over time.

What is the role of genetic evidence in supporting evolution?

Back

Genetic evidence, such as DNA sequencing, shows how closely related different species are and helps trace their evolutionary history.

What is a common ancestor?

Back

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

What is the difference between homologous and analogous structures?

Back

Homologous structures arise from a common ancestor, while analogous structures arise independently in different species due to similar environmental pressures.

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.
