Gene pools and speciation
Understandings:
• A gene pool consists of all the genes and their different alleles, present in an interbreeding population.
• Evolution requires that allele frequencies change with time in populations.
• A gene pool consists of all the genes and their different alleles, present in an interbreeding population.
• Evolution requires that allele frequencies change with time in populations.
Reproductive isolation of populations can be temporal, behavioural or geographic.
Skill: Comparison of allele frequencies of geographically isolated populations.
Skill: Comparison of allele frequencies of geographically isolated populations.
Theory of knowledge:
Punctuated equilibrium was long considered an alternative theory of evolution and a challenge to the long established paradigm of Darwinian gradualism. How do paradigm shifts proceed in science and what factors are involved in their success?

Awesome history of geneticists!
