Evolution

A species is a group of similar organisms that

• can mate with each other and produce fertile offspring
• can live together on an island
• can migrate to an island from the mainland
• all have exactly the same traits

1. A trait that helps an organism survive and reproduce is called a(n)

• variation.

• adaptation.

• species.

• selection.

1. Similar structures that related species have inherited from a common ancestor are called

• adaptations.

• punctuated equilibiria.

• ancestral structures.

• homologous structures.

What was the name of Darwin's ship?

• HMS Beagle
• HMS Lab
• HMS English Bulldog
• HMS Husky

What did Darwin observe about finches in the Galápagos Islands?

• Their feathers were adapted to match their environment.

• Their beaks were adaptations related to the foods the finches ate.

• They had identical genotypes in all locations.

When an organism completely dies out, it is called.....

• Adaption
• Extinction
• Fossilization
• Mutation

Individuals who are considered fit, have:

• Stronger genes
• Fewer mutations
• More food
• More offspring

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

• theories
• variations
• adaptations
• genes

Why are advantageous traits more likely to be passed on to the offspring?

• Because parents with those traits can teach their offspring
• Because parents with those traits can surive and reproduce better
• Because parents with those traits care more about their offspring
