Natural Selection Practice

What was the name of the scientist who had the Theory of Evolution?

• Lamarck
• Einstein
• Washington
• Darwin

When organisms with the best adaptations survive and reproduce (and therefore pass their traits along to offspring), this is called:

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

Finches on the Galapagos Islands all come from a common ancestor. Over millions of years, the beaks on the finches living on each island changed. Why did this happen?

• They wanted to look different to help them blend in
• They adapted to eat the food available on their island
• They wanted to protect themselves against predators
• Their beaks didn't actually change

Evolution is a

• law
• theory
• hypothesis
• conclusion

Natural selection is when ____________ decides who survives and who doesn't.

• nature
• humans
• animals
• years

What did Charles Darwin think about natural selection?

• organisms change their traits to the trait that will help them
• breeding 2 similar animals get the best traits
• breeding 2 animals with different traits give the best results
• organisms with better traits for their environment will survive and reproduce

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

• natural selection

• mutation

• camouflage

• adaptation

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.

The differences among a species, like different bird beaks, are called

• genes
• variations
• traits
• theories

Mutations are a change in what?

• DNA
• tRNA
• genotype
• phenotype
