Traits functional explanation

A functional explanation for a particular trait does not stipulate by which mechanism within the organism a particular effect is produced. The function can be realized in physically different ways and the only relevant feature is that it must enhance fitness, i.e. serve survival and reproduction (Macdonald, 1992). Various causal factors can then be invoked to explain how the function is performed, although these factors cannot explain why the traits are present unless an appeal is made to selection pressure. 

One trait I do see in many leaders is an imderline of their name. This is a bit of an explanation mark signifying our own importance. This doesn t bother me as a grapho-therapist. As long as we don t have arrogance, I think ego is a healthy function of a balanced person.
