• They must be able to mate

• They must be able to produce viable offspring

• They must have structural similaries

• They must have the same bone structure

The formation of a new species is called

• Natural selection

• Struggle for existence

• Speciation

• Darwinism

Evolution is...
(according to the video)

• A change in the gene pool
• A field of study where one studies weather.
• The study of rock strata.
• The study of cladograms

• the opposite of natural selection

What is non-random mating?

• proof of common ancestry
