Evidence of Evolution Reviewer

Front

What is the current method of classifying organisms?

Back

Organisms are classified according to their biological ancestry.

Front

Why were some strawberries able to survive a hard freeze?

Back

They have different genetic variations that cause them to be more resistant to cold temperatures.

Front

What is likely to happen to furry and thin-furred rabbits if global temperatures drop?

Back

The furry rabbits will survive and reproduce while the thin-furred rabbits will die early, resulting in a greater number of furry rabbits in the population.

Front

How can a paleontologist prove that a fossil is related to modern-day ferns?

Back

By comparing the structures of the fossil to that of modern-day ferns.

Front

What is the term for an adaptation that allows an organism to blend into its habitat?

Back

Camouflage.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals within a species, which can lead to different traits.

Front

What is natural selection?

Back

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

Front

What is a fossil?

Back

A fossil is the preserved remains or traces of a once-living organism, often found in sedimentary rock.

Front

What is the significance of comparing structures in evolutionary biology?

Back

Comparing structures helps scientists determine evolutionary relationships and common ancestry among species.

Front

What is adaptation in the context of evolution?

Back

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