Adaptations shaped by natural selection:
a) are magnified and enhanced through genetic drift
b) are unlikely to be present in humans living in industrial societies
c) may be out of date, having been shaped in the past under conditions that differed from those in the present
d) represent perfect solutions to the problems posed by nature
e) are continuously modified so that they are always matched to the environment in which a population lives

e) are continuously modified so that they are always matched to the environment in which a population lives

Explanation:

The role of natural selection is to select individuals best adapted to a given ecological condition, allowing them to survive and leave descendants in a given environment.

Natural selection acts permanently on all populations. Even in stable and constant environments, natural selection acts in a stabilizing manner, is present, eliminating divergent phenotypes.

However, the environment does not represent a constant and stable system, in fact, it is always changing, both over time and throughout space, which determines different interactions between organisms and the environment.
