Evolution Unit Review

In natural selection, the selective agent is the

• humans

• mutations

• breeders

• environment

Mutations are important because they bring about

• death of the organism in which they develop

• genetic variation needed for a population to evolve

• benefits for the individual, not for the population

• Hardy-Weinberg equilibrium within a population

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

• variation

• adaptation

• homologous structure

• vestigial structure

What is the process in which humans breed organisms for certain traits?

• natural selection

• inheritance

• artificial selection

• descent without modification

Charles Darwin came up with this theory

• Natural Selection

• Mutation

• Punnett squares

• Hardy-Weinberg equilibrium

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

• vestigial structures

• analogous structures

• homologous structures

• fossil structures

The gradual change in a species over time is...

• Adaptation

• Natural Selection

• Mutation

• Evolution

Gigantopithecus were very large primates that lived 500,000 years ago. Since none of these mammals are still here today, they are said to be...

• Endangered species

• Declining

• Extinct

• Threatened

Scientists have collected millions of fossils of different organisms and have developed a timeline of life on Earth. What do we call this?

• Mutation

• Natural Selection

• The theory of evolution

• Fossil Record

Ostrich wings are an example of...
