Operationally define "adaptation" please. |
An adaptation is a trait with a current functional role in the life of an organism, where the function evolved by and is presently maintained by natural selection. To demonstrate this, it needs to be shown that the trait is under genetic control (is inheritable), and that variations in the trait result in variations in success at meeting the challenges of life, leading to variations in success at reproduction.
Genetic evidence for positive selection includes rapid divergence of functional sites between species and suppression of polymorphism within a species. Positive selection is common across a wide range of species in genes that are involved in host–pathogen interactions, reproduction, dietary adaptation, and appearance. Another category of genes that commonly show positive selection are genes that affect distinctions from closely related species, for instance in humans involving behavior, brain anatomy, and the sensory systems.

But that was a nuisance request on your part, wasn't it, because you have yet to provide usable operational definitions (or even logically valid regular definitions) for any of the terms and concepts that you use and abuse. You have shown that "operational definition" is not a concept that you understand.
