So I wonder about how many people have technically been helped by that versus the number of people who have been harmed by diseases they may have acquired from a rat.

The common ancestor was an animal that lived in the late Cretaceous around the time of the dinosaurs. There's not a specific name, but we use genetics to understand how far back these common ancestors lived. The anatomy and behavior of that common ancestor was much more rat-like than it is human-like. They were likely nocturnal. Some of them may have been insectivores.

And their basic anatomy was much more rat-like than humans.

Yeah, so that makes rats good model organisms because you can have many offspring within your human life as a scientist studying them. So you can see how things translate from one generation to the next. One rat female can have up to 72 pups per year. Wow. Wow.
