Natural Selection

Behavioral changes of individuals of a species that allow for better survival. (Acquired traits)

• Variation

• Adaptation

• Behavior

• Environment

When every organism of a species has died.

• Evolution

• Natural Selection

• Extinction

• Artificial Selection

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

• Evolution

• Natural Selection

• Extinction

• Artifical Selection

What are the most studied animals in the galapagos?

• Finches

• Tortoises

• Turtles

• Lizards

What is the advantage of having different shaped beaks?

• To look different from other species.

• To be able to eat the food readily available in the environment.

• To protect itself against predators.

• To protect itself against prey.

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

Why do frogs and other organism reproduce so many eggs or offspring?

• so that their babies can have friends to play with

• the more offspring the more likely the offspring will survive

• the more offspring the less likely offspring will survive

• the more offspring the less competition

Which organisms are most likely to survive?

• the best adapted

• the fastest

• the strongest

• the most domesticated (tamed)

Any inherited trait that gives an organism an advantage in its environment is called ___.

• a mutation

• an adaptation

• evolution

• natural selection
