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
