Evolution and Adaptation Study Guide

What is natural selection?

• When reproduction occurs and mutations happen.

• When a offspring has the traits from its parents.

• When an organism is able to camoflauge in its environment.

• the process whereby organisms that are better adapted to their environment tend to survive and reproduce more offspring.

What is a mutation?

• When animals have extra legs

• When a frog has 3 eyes

• When genes or DNA have been alterd or changed

• When RNA is upside down

What must organisms do when an environment changes?

• Adapt

• Camoflauge

• become common

• fight

Evolution is best defined as:

• the process which organisms die.

• the process which organisms change over time.

• the process which organisms that are extinct become revived.

• the process which non-living things fossilize.

The solidified remain or imprint of a once living thing are called:

• Fossils

• Homologous Structures

• Vestigial Structures

• DNA

Adaptations are:

• physical or behavioral tendencies.

• physical or behavioral characteristics that help an organisms survive and reproduce.

• physical or behavioral characteristics that do not help the organism in any way.

• genetic mutations that have gone wrong.
