Evolution Review

In natural selection

• The natural environment determines which individuals are fit to survive

• The natural enviornment determines which individuals are fit to reproduce

• Some individuals of a species will have a genetic advantage over other

• All of these

Variation within species leads to

• New species being developed

• The extinction of a species

• Members of the species mating with another species

• None of these

Speciation is when

• A species adapts to its environment

• A species becomes more fit

• New species are created from an original species

• None of these

A species of desert lizard developing over time feet that can stand hot sand temperatures is an example of

• Speciation

• Variation

• Adaptation

• None of these

A species of fish is either blue or white. The blue fish better blend into the water and are less likely to be eaten by predators. Over time, there are more blue fish than white fish. What has happened?

• Variation

• Speciation

• Natural Selection

• Inheritance

Adaptation is......

• When new species are created

• When a species adapts to its surroundings to survive

• When a species moves its habitat

• None of these

Inheritance in Biology is when

• An animal moves its habitat.

• An animal dies and its children live in the same habitat

• An animal mates with a different species creating a hybrid

• An animal passes on its genetic traits

Did Humans evolve from Chimpanzees?

• Yes

• No

• We don't know

• Maybe
