Chapter 24 Species and Speciation

Biological species concept: populations belong to the same species if they can contribute
genes to a common gene pool. If they can reproduce and form viable offspring together
Conspecifics are organisms or populations that belong to the same species.
Reproductive barriers: block gene flow between different species

Morphological species concept

Phylogenetic species concept




Prezygotic and postzygotic barriers




Genetic drift: a random change in allele frequencies over time

Reinforcement: a type of natural selection called disruptive selection, which favors extreme
phenotypes over intermediate phenotypes
