1. Lactase persistence is an example of gene-culture coevolution because a the genetic mutation for lactase persistence constitutes a form of transmitted culture.

b. a cultural practice (dairy farming) was a selection pressure that led to a genetic mutation (lactase persistence) among dairy farming populations. C d of a genetic mutation (lactase persistence), despite there being no selection pressures, but it enables people to engage in a cultural practice (digesting milk into adulthood). a genetic mutation (lactase persistence) led to the creation of a cultural practice (dairy farming) e adults with lactase nonpersistence, but who drink a lot of milk, will develop the genetic mutation for lactase persistence.
