Unit 5 Review

Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring?

• Variation

• Adaptation

• Evolution

• Natural Selection

What is another name for natural selection?

• Survival of the biggest

• Survival of the fittest

• Survival of the smartest

• Survival of the fastest

What would indicate that a series of fossils represent evolution?

• the fossils were completely different

• the fossils were identical

• the fossils were found in the same layers of rock

• the fossils show similarities

What is the term for a feature that allows an organism to survive better in its environment?

• Adaptation

• Homologous Structure

• Vestigial Structure

• Variation

A physical or behavioral trait that helps an organism survive and reproduce in its environment is called a what?

• An adaptation

• A response to a stimulus

• A mutation

• Evolution

Mutations are important because they bring about

• genetic variation needed for a population to evolve

• death of organisms in which they develop

• Hardey-Weinberg equilibrium within a population

• benefits for the individualm not for the population

When looking at two birds of the same species, you notice that one has darker feathers than the other one. You also notice that one has a beak that is just a little longer. These slight differences within members of the same species are called...

• Fossils

• Extinction

• Variation

The science of describing, classifying, and naming living things is called:

• Geology

• Chemistry

• Biology

• Taxonomy

When an organism completely dies out, it is called...

• Adaptation

• Mutation

• Fossilization

• Extinction

Some organisms that share a common ancestor have features that have different functions, but similar structures. These are known as

• vestigial structures

• homologous structures

• analogous structures

• fossil structures
