Natural Selection

Telling age by the amount of change in a radioactive element

• natural selection

• camouflage

• radiometric dating

• embryology

• gradualism

This theory states that species change little for a long period of time then, during a relatively short period of time, under significant change resulting in a new species.

• punctuated equilibrium

• biogenesis

• gradualism

• evolution

When an organism blends into its environment

• natural selection

• camouflage

• radiometric dating

• embryology

• gradualism

Evolution is a ____________ process.

• fast

• extinct

• new

• slow

This theory states that a continuing series of small variations will result in a new species over time.

• punctuated equilibrium

• biogenesis

• gradualism

• evolution

An inherited trait that makes an organism different from others of its species

• variation

• adaptation

• evolution

• biogenesis

A trait that makes an individual different from others of its species

• Variation

• punctuated equilibrium

• species

• Lamarck

The Theory that organisms with traits best suited to their environment are more likely to survive and reproduce.

• gradualism

• "on the origin of species"

• acquired characteristics

• natural selection

Study of the development of the embryos of organisms

• natural selection

• camouflage

• radiometric dating

• embryology

• gradualism

Which of the following is NOT one of the 5 principles of natural selection?
