... are identical. For example the region coding for active site will be probably conserved, while some loops on surface of the protein will be divergent. Both on DNA and amino acid level. You can design primers on the divergent regions and then they will be species-specific, because they will ...

Phylogeny also is needed to understand when you're looking at divergent (new species in same clades evolving in parallel) or convergent (new pollinator / plant relationships built on shift in old abilities) evolutionary patterns.

except of different EC class? Not much :o) The mechanism will be probably different, but that will be probably divergent even in the classes.

... documented across the range of G. aculeatus, including among populations separated for millions of years... Another possibility, then, is that the divergent selection is not strong enough to generate irreversible barriers through ecological speciation. Equivalently, assortative mating may not be ...

... & McPhail 1999). Consequently, they fulfill the principal criteria of biological species. It has been well argued that ecological speciation, divergent selection involving exploitation of alternative trophic niches owing largely to resource competition, has been a major deterministic factor ...
