Evolution Review

All the field mice that live in a field of light colored grass have tan fur. One of the mice is born with black fur. What could cause the black fur color?

• Mutation

• Selective breeding

• Adaptation

• Natural selection

What is an inherited trait that gives an organism an advantage in its particular environment called?

• Variation

• Divergence

• Adaptation

• Mutation

The process by which a species passes out of existence is known as -

• De-speciation

• Genetic diversification

• Habitat destruction

• Extinction

We have many species currently living that are so rare or otherwise threatened that they may soon disappear. What term is used to refer to these animals?

• Endangered

• Exotic

• Extinct

• Beloved

In evolutionary theory, what is meant by "survival of the fittest"?

• Only the fastest, biggest, and strongest individuals survive.

• Species gradually become perfectly adapted over a long period of time.

• Individuals that best fit the "ideal" of a species are the only ones to survive.

• Individuals that best adapt to their environment have a greater chance of reproducing.

A change in successive generations of organisms due to a change in the organism's surroundings is called a/an

• Stimulus

• Development

• Adaptation

• Evolution

Which of these conditions is most likely the result of a genetic mutation?

• Color blindness

• Freckles

• Blue eyes

• Red hair

A sudden change in a characteristics caused by a change in a gene or a chromosome is called a/an

• Alteration

• Variation

• Mutation

• Assortment

When Darwin visited the Galapagos Islands, he found some unrelated species that resembled each other due to

• Homologous structures in each of the species

• Competition with each other for food

• Similar environmental factors

• Similar genetic mutations

The concept that living organisms have continuously changed over long periods of time is called

• Ecology

• Embryology

• Evolution

• Spontaneous generation
