Question

According to the developmental systems model, normal or typical developmental sequences occur due to both the influences of species-typical genes and the influences of __________.

Answer 1

Answer : a species-typical rearing environment.

Step-by-step explanation:

The developmental system model explained evolution as a change that occur not in gene frequencies, but explained in spatial and temporal structure of developmental system.

In this case, developmental system models did not based development only in evolution but also in species-typical rearing environment. This means, development is based on the influences of special-typical genes and species-typical rearing environment.
