Evolutionary Trees

Front

What type of evolutionary evidence is shown by humans and bats having similar looking forelimbs?

Back

Anatomical evidence refers to the similarities in structure between different species, indicating a common ancestor.

Front

What is an inheritable characteristic that gives a survival advantage to an organism?

Back

Adaptation is a trait that enhances an organism's ability to survive and reproduce in its environment.

Front

Why do scientists classify organisms?

Back

Scientists classify organisms to see how they are alike and different from each other.

Front

Where is the most common ancestor of the sponge and mouse located on an evolutionary tree?

Back

Point E represents the most common ancestor of the sponge and mouse.

Front

If species A and B have very similar genes and proteins, what can be inferred?

Back

Species A and B share a relatively recent common ancestor.

Front

What is a derived character in evolutionary biology?

Back

A derived character is a trait that is present in an organism but was absent in the last common ancestor of the group being considered.

Front

What does a phylogenetic tree represent?

Back

A phylogenetic tree illustrates the evolutionary relationships among various biological species based on their physical or genetic characteristics.

Front

What is the significance of homologous structures in evolution?

Back

Homologous structures indicate common ancestry, as they are similar in structure but may serve different functions in different species.

Front

What is the difference between convergent evolution and divergent evolution?

Back

Convergent evolution occurs when unrelated species develop similar traits due to similar environments, while divergent evolution occurs when related species evolve different traits.

Front

What role does natural selection play in evolution?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.
