Natural Selection is BEST described as

• Ability to generate new traits that better suit the species

• Increasing the perfection of a species

• Gradual change in existing traits over time

• Causing the death of a large portion of the population

If weather in normally warm ecosystems changes to become cold, what change might occur?

• Cold weather would cause mutations to make organisms adapt

• IF a mutation occurred for thicker fur, it will be passed on

• Evolution would occur resulting in extinction

• Nothing would change
