			B)	False
2			According to the phylogenetic species concept, a species is a the smallest set of organisms that share an ancestor and can be distinguished from other such sets.
			A)	True
			B)	False
3			Speciation can occur as a result of reduction in gene flow between two populations.

			B)	False
4			Allopatric speciation occurs within the home range of the parent species.
			A)	True
			B)	False
5			Chronospecies represent different stages in the same lineage as they evolve over time.

6			Assigning organisms to species is straightforward in modern biology.
			A)	True
			B)	False
7			The northern and Mexican spotted owls are an example of allopatric speciation.
			A)	True
			B)	False
8			For speciation to occur, populations must be isolated by a geographic or ecological barrier.
			A)	True
			B)	False
9			Diane Dodd's experiment with fruit flies is evidence that geographic isolation may lead to speciation.
