  1. Humans like dogs have the ability to speciate quickly. But all dogs, regardless of appearance, know other dogs are just dogs. Humans nearly died out 70,000 years ago from the aftermath of the Toba eruption. Neanderthal, devonisian and archaic African genes added, depending where you're from. The furthest outliers from the rest of us are the Australian people. They have exceptionally visual abilities that alas most of us lack. But why do they have a 25% denser visual cortex and 25% better eyesight? Because it was imperative in the outback. Theres two types of vegetation apparently. One will have food and the other won't, and figuring that out from 10 miles away is a massive advantage. Humans are curious.
