can you tell me about the trait mentioned above?
It is a distinct variant of a phenotypic characteristic of an organism.
Phenotypic trait
A phenotypic trait, simply trait, or character state is a distinct variant of a phenotypic characteristic of an organism; it may be either inherited or determined environmentally, but typically occurs as a combination of the two.
how does natural selection work as a mechanism of evolution A prerequisite for natural selection to result in adaptive evolution, novel traits and speciation is the presence of heritable genetic variation that results in fitness differences. what is the role of darwin in it? He defined it as the "principle by which each slight variation [of a trait], if useful, is preserved". what can you tell me about its terminology? The term is most often defined to operate on heritable traits, because these directly participate in evolution. how does the classification take place? It can act on any heritable phenotypic trait, and selective pressure can be produced by any aspect of the environment.

Phenotypic trait [SEP] Introduction
A phenotypic trait, simply trait, or character state is a distinct variant of a phenotypic characteristic of an organism; it may be either inherited or determined environmentally, but typically occurs as a combination of the two. For example, eye color is a character of an organism, while blue, brown and hazel are "traits".
