We used to taxonomically or phylogenetically classify, based on phylogeny. Now we're into an area of genomics, and I think this is adding a whole new dimension to the definition of what a “species” actually is. The old definition of “species” that I grew up with or that I went to school with was basically two organisms that could produce fertile offspring.
Is that still the scientific definition of a “species”? That's not what the definition is in the act.
