    The crazy thing about this is not just how evolution reverse-engineered what a snake looks like to a bird (or whatever preys on this moth), but also that some birds are born with an image burned into their brains labeled “avoid.” Snakes are such a problem to animals that may also prey on this moth, that a moth was able, over millions of years of evolution, to mimic that image through selective pressure. We’re not seeing here a moth mimicking a snake, we are seeing a moth’s wings resembling the image its prey holds in its brain of what it should identify as its own predator. An image that, itself, is held genetically and passed down from animal to animal, built by its own selective pressure. It’s amazing that this could produce such a clear image that’s immediately recognizable to us.

    I’m pretty sure most adult dogs and cats understand mirrors, they just get creeped out by their own reflection. Take an adult cat, hold it up to a mirror. Watch as it actively avoids looking at itself. My dog stares at me for long periods through a full-length bedroom mirror and even barks and runs to the window when she sees dogs outside through it. Doesn’t really care much about her own reflection.








  • I could’ve sworn Jim Beam whiskey was Jim Bean. A friend of mine had a poster of a whiskey bottle on his wall that I stared at every time I was there. He was a minor at the time and didn’t drink, so I always wondered why he had it up. Years later I saw a Jim Beam bottle and had a Mandela moment. The Berenstein Bears and Mandela dying in jail were things I believed, too, but I think the whiskey one is one I haven’t heard from anybody else, yet.
