How does the idea that adaptation is the \"alternate hypothesis\" or \"innocent until proven guilty\" differ from the idea that natural selection is the main force of evolution?

Solution

Natural selection : There is variaion in the living and reproduction in a population. This occurs because the genetic (inherent) characteristics of the members of the populaton interact with the environment. This results in a heightened fitness of the organism for the selection.

Adaptation: The characteristics like form or function which increases the fitness and chance of survival.

The main difference is that adaptation is an outcome of natural selection.
