Evolution Review

Front

What is speciation?

Back

Speciation is the process by which new distinct species evolve from a common ancestor, often due to populations becoming reproductively isolated.

Front

When does speciation occur?

Back

Speciation occurs when populations can no longer interbreed.

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 an adaptation?

Back

An adaptation is a characteristic that enhances an organism's ability to survive and reproduce in its environment.

Front

What happens to a population of white mice in a brown sand environment over time?

Back

The population of white mice will likely decrease due to natural selection favoring the brown mice, which are better camouflaged.

Front

What is the significance of allele frequency in evolution?

Back

Allele frequency refers to how common an allele is in a population; changes in allele frequency can indicate evolution.

Front

What is the difference between evolution and individual adaptation?

Back

Evolution refers to changes in populations over generations, while individual adaptation refers to changes in an individual's traits during its lifetime.

Front

What is a common misconception about evolution?

Back

A common misconception is that individuals can evolve; evolution occurs at the population level.

Front

Which group is most closely related to primates?

Back

Rodents and rabbits are most closely related to primates according to evolutionary diagrams.

Front

What role does the environment play in evolution?

Back

The environment influences which traits are favorable, driving natural selection and evolution.
