monogenesis

Some held that negritude was a product of living under the tropical sun, a perhaps beneficial adaptation to a fierce climate – an environmentalist solution chiming with monogenesis and Lockean malleability models.

The view that one parent tale in one fixed location spawned numerous progeny the world over has come to be known as the theory of monogenesis and diffusion. The contrasting theory of polygenesis assumes that resemblances among tales can be attributed to independent invention in places unconnected by trade routes or travel.
