It seems they grew to fill an ecological niche left by the dinosaurs, aided by a cooling climate and greater amounts of rabies land procedure mass that supported large body sizes.
The maximum size of mammals began to increase sharply about 65 million years ago, peaking parasite rabies in the Oligocene procedure Epoch (about 34 million years ago) in Eurasia, and again in the Miocene raboral Epoch (about 10 million years ago) in Eurasia and Africa."The consistency of the pattern strongly implies that biota in all raboral regions were responding to the same ecological constraints.".This is what paleontologists have long wondered."A big part of science is seeing patterns, and then producing new hypotheses procedure and testing them he said.I was reading this wiki article on rabies.It is very early common for a virus to be raboral able to infect only one species or a limited number of related species.In horses the "Transmission" section, it states: "All warm-blooded species, including humans, may become infected with the rabies vaccine virus and develop symptoms.Why does rabies affect some mammals, but rabies not others?Rabies is unusual because it can infect such a large number of different mammals.Viruses get into cells by attaching to specific molecules on the surface procedure of cells.But they quickly evolved procedure to be as big as dinosaurs, then evolved to be smaller again.So, if i'm reading this correctly, all mammals are automatically susceptible, the virus has adapted to infect "cold-blooded vertebrates but procedure leaves birds asymptomatic and recovering.I hope I helped.Even more interesting is that mammals didn't reach some "upper biomechanical limit" to their body sizes - they could epidemic have grown much larger. The mammals that are immune to rabies presumably lack the surface molecule rabies that the virus latches onto in other mammals.
