Level 2 is essentially reductionistic, and thus all the criticisms of reductionism under the adaptationist program apply to level 2.

However, the counterargument is that fitness maximizing behavior may become prevalent in a group through cultural transmission, without any changes in the gene pool (Kitcher, 1987).
