More about evolution

Yesterday I heard that Laura Erickson's dog Photon had to have some teeth pulled because they were badly decayed. Dental infections can lead to a lot of heart problems in mammals. Now I don't want to be snarky, but this is yet another way that we birds are light-years more evolved than humans and other mammals. We got rid of teeth ages ago--what's the point of having something that causes so many problems at so many points in life, and isn't aerodynamic to boot? Teeth are just SO reptilian!
