When every organism of a species has died.

• Evolution

• Natural Selection

• Extinction

• Artificial Selection

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.

The theory of evolution by natural selection means that what is changing over time?

• The inherited traits of a population.

• The acquired traits of a population.

• Hair color and eye color

• Attractive features.

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

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

• natural selection

• mutation

• camouflage

• adaptation

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)

Do organisms "decide" to evolve and change?

• Yes, they know they need to change to survive 

• No, they change because of natural selection

Since the 1800s humans have stopped burning coal, and the trees have returned to their original color. Which moth will be more successful in this environment?

• Both will be equally successful

• Neither will be successful
