That’s not “science,” that’s just an arbitrary convention that can help simplify communication of complex toppics. The genetic data that the convention is derived from is the science, in the form of a lineage of genetic relations between organisms and nothing else, because biology has exactly zero built-in categories or labels, and those are all human-made.
But even with more modern methods like cladistics and genetic analysis, birds are still found to be directly descended from contemporary dinosaurs.
