You may see the depiction of a pug more than once in my cartoons and comic strips. I used to have one and they are hilarious little clowns. But often I’d be staring at my pug, name of Cricket by the way, and I just kept thinking, “THAT came from a wolf?” It’s one of the best examples of the variety within a species by way of artificial selection. Natural selection on the other hand would have wiped pugs out long ago if set free into the wild. We picked them for cuteness but they have breathing problems, bad hips and they like to fart alot (especially going up the stairs). Natural selection looks to save survival traits and toss out health issues unless it’s a trade off for another feature that is useful.
