Infants are all lactase (+: normal allele. New caloric source available to individuals who can drink milk: food value, water content. Allows them to live longer & produce more offspring who can also drink milk. Pop. gene frequency shifts toward lactase (+) Pastoralism: economy in which cattle, sheep, goat, camel, etc.
