Unit 6 Part 1

How do you "win" at natural selection?

• survive

• go extinct

• survive & reproduce

Survival of the Fittest and Evolution were proposed by what scientist?

• Charles Darwin

• Albert Einstein

• Steven Hawking

• Isaac Newton

What word describes a trait that helps an organism survive in its environment?

• natural selection

• mutation

• camouflage

• adaptation

Change over time

• Natural Selection

• Selective Breeding

• Homeostasis

• Evolution

Dogs such as Chihuahuas are examples of....

• Artificial Selection 

• Natural Selection 

• Mutations 

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution

• Natural Selection

• Extinction

• Artifical Selection

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.

• Because they come from dominant alleles.

• Because they come from recessive alleles.

• Because the trait is an acquired phenotype.

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice

• The hawks eat more dark mice than light mice because the dark mice taste better

• The hawks eat more light mice than dark mice because they can see the light mice more easily

• The hawks eat more dark mice than light mice because they can see the dark mice more easily

Do organisms "decide" to evolve and change?

• Yes, they know they need to change to survive 

• No, they change because of natural selection

Almost all adaptations started off as?

• selective breeding

• physiological

• structural

• mutation
