...dinosaurs are extinct, right?
But the closest genetic relative to the dinosaur is an animal we've all seen (and almost all eaten), an animal so common we don't even think about it twice.
Yup - the humble chicken is the most dinosaur-like of all birds, genetically. (The second most is, of course, the turkey).
Also, birds evolve more slowly than mammals, possibly explaining why none of the flightless birds have invented livebearing yet. (And the slowest evolution? Crocodilians).
(My dear darling husband will insert a Doom Chicken joke here. It's a bad movie reference).
