Natural Selection & Evolution

an inherited behavior or physical characteristic that helps an organism survive and reproduce in its environment.

• adaptation

• natural selection

• niche

• competition

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

• Charles Darwin
• Albert Einstein
• Steven Hawking
• Isaac Newton

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.

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

• natural selection

• mutation

• camouflage

• adaptation

The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?

• Dark moth
• Light moth
• Both will be equally successful
• Neither will be successful

Change over time

• Natural Selection
• Selective Breeding
• Homeostasis
• Evolution

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

These moths are all the same species. The differences between their wings is an example of ________________

• Natural Selection
• Variation
• Homeostasis
• Extinction

Dogs such as Chihuahuas are examples of....

• Artificial Selection 
• Natural Selection 
• Mutations
