Following up his delightful video explaining evolution with emojis, science guy Bill Nye delves into the evolution of the dog. While not an in-depth dissertation – the video is only 3.5 minutes, after all – he hits on the major points, such as how the evolution of dogs was very likely a deliberate human intervention. Domestic foxes, for example, develop doglike physical characteristics such as floppy ears in as little as three generations.
He also ties in the comparison between breed and race, in that both are artificial constructs. Two dogs, whatever the breed, will result in more dogs; two humans, whatever the race, will result in more humans.
You can watch him explain it all AFTER THE JUMP…
