3.
What is common descent?

4.

5.
What is multiplication of species?
Answer: The fact that over time, more species are created. Due to variation in populations, new adaptations result in the possibility for the formation of new species.
6.
What is allopatric speciation?
Answer: Allopatric (\"from another land\") speciation occurs when a Reproductive Isolating Mechanism (RIM) divides a population by some barrier, such as a mountain, river or ocean. Isolated populations then undergo indepenant evolution.
7.
What is a species?
Answer: A species is a reproductively distinct population of an organism that differs from others in organismal form.
8.
What are Reproductive Isolating Mechanisms?
Answer: Barriers that prevent two species from producing viable offspring.
9.
What are the types of RIMs?
Answer: Prezygotic where fertilization is prevented, and Postzygotic where fertilization occurs but offspring produced are weak, non viable, or sterile and cannot produce offspring (E.G. mules)
10.
What is gradualism?
Answer: Small and continuous changes in phenotypes
