Which source of evidence is evolution is used to establish genetic relationships between organisms? 

DNA

100

Randomly introduces new alleles into a population

Mutation

100

Two populations of the same species grow distant from one another. At what point will these two populations become different species?

a) when they are no longer able to interbreed

b) when there is a physical barrier between them

Which statement aligns best with Lamarck's view of evolution?

a) A giraffe stretches its neck to browse higher trees, over time this giraffe will have a longer neck and the offspring of this giraffe will have long necks.

b) Giraffes with long necks will be more likely to reproduce, passing on their genes.

a) A giraffe stretches its neck to browse higher trees, over time this giraffe will have a longer neck and the offspring of this giraffe will have long necks.

Which best describes natural selection? 

a) biological change through time in a population

b) the process by which individuals with advantageous traits survive and reproduce more successfully

True or False:

Cuvier believed that species became extinct when the Earth experienced a revolution. 

True.

A revolution was a natural disaster so violent that it killed numerous species.
