It could be even narrower than that. Some modern animals (particularly
primates) only develop
fully mature male characteristics once they become the alpha male in a group.
It seems that in
some species, the presence of a dominant male will suppress hormone production
in other male
members of the group, preventing them from fully realising their developmental
potential. I believe
it's known as either socioendocrinology or psychoendocrinology.
