Evolutionary biologists, across the board, understand that the goal of all organisms is to reproduce. I believe you have mistaken this axiom of biology to mean that the goal of evolution is reproduction. Natural selection deals with variation occurring within populations. It has no ability to rearrange the make up of an organism towards some goal. It affects only the fitness of organisms with in populations.
Fitness is a relative measure.
It is not some absolute property of the organisms and is subject to change. Populations that have lost natural variation cannot respond to new environmental challenges and go extinct. Wilson makes this clear in his book. It was a groundbreaking book. Wilson was the first to understand that behavior, like the physical aspects of an organism, are subject to natural selection and are thus the product of natural selection, and propose testable hypotheses about the mechanisms by which they evolved.
