Natural Selection

Adaptations can be:

• camouflage

• ability to survive cold weather

• hunting skills

• all of the above

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

When every organism of a species has died.

• Evolution
• Natural Selection
• Extinction
• Artificial Selection

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

• natural selection

• mutation

• camouflage

• adaptation

Which organisms are most likely to survive?

• the best adapted
• the fastest
• the strongest
• the most domesticated (tamed)

Change over time

• Natural Selection
• Selective Breeding
• Homeostasis
• Evolution

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.

Mutations are a change in what?

• DNA
• tRNA
• genotype
• phenotype
