    If it was not noticeably cuter, then it would cause no advantage and the theory falls. (Which is possible, of course.)

    On a 5cm snout, 3.5% is less than 2 mm. You not only wouldn’t notice it with the naked eye, it’s almost a small enough difference to get lost in the noise .

    The study is saying they’re already seeing these imperceptible differences in racoons they’re measuring.

      We are more hostile to ugly raccoons and more often helpful to cute ones. This isn’t evolution, it’s selective extinction based on cuteness, would be my guess. One example of the power humans have in shaping the natural world around what our emotions tell us to.

      There is no such thing as an ugly raccoon.

        Wow that’s interesting!

        The study lays out the case that the domestication process is often wrongly thought of as initiated by humans—with people capturing and selectively breeding wild animals. But the study authors claim that the process begins much earlier, when animals become habituated to human environments.

        “One thing about us humans is that, wherever we go, we produce a lot of trash,” says the study’s co-author and University of Arkansas at Little Rock biologist Raffaela Lesch. Piles of human scraps offer a bottomless buffet to wildlife, and to access that bounty, animals need to be bold enough to rummage through human rubbish but not so bold as to become a threat to people.

        This has absolutely blown my mind. I don’t think I’ve ever considered that, obviously.

        It’s a popular theory about why dogs were domesticated so much earlier than everything else. Wolves have a remarkably similar lifestyle to human hunter gatherers, and so early dogs could live either in parallel or in close proximity as conditions demanded. With other creatures, like pigs or horses, humans had to run a program and do so consistently for domestication to work. In some places, semi-feral dogs are still a common sight.

          Yeah, I don’t think racoons are anywhere near going extinct…They’re really well adapted to living on the fringes of human society

          Also, it’s not just preference. Cuter is less threatening, and for the noble North American trash panda? Convincing humans to help them escape dumpsters is practically part of their life cycle

            You assume it’s a one-way street.

            Humans having a proclivity towards “cute” animals is as much an evolved trait as animals becoming “cuter” to better adapt to presence.

            Hell, for that matter, it isn’t just us that have a proclivity towards “cuteness”. It exists in plenty of species, we just tend to be the ones most prone to it outside of very similar species.

            It is absolutely evolution because it isn’t selective.

            I don’t understand your last sentence. Selection a main mechanism of evolution.

              My across the street neighbor feeds the racoons cat food. They rip up my garden and antagonize my dogs all night. I tried to scare one away just last night by yelling and waving my arms, but they just stared at me like “yeah ok dude” and went back to their racoon business. They are not afraid of people in the slightest and you could probably pet one if you were so inclined. It sucks 😅

                    Wolves also do not understand pointing, most other human gestures and they can not read human emotions through our faces. Dogs can understand all that. Humans and dogs have co-evolved for such a long time that our species now have a deep instinctual understanding of each other.

                    My dogs definitely do not understand pointing! No arguing, they just don’t get it, though they could be trained to I’m sure.

                      I think the hangup is thinking evolution can’t proceed quickly. We were taught in school that evolution take millions of years and we resist the idea that it can move quickly.

                      We’ve been figuring out over the last two decades that evolution can move fast, given enough selective pressure.

                      Arguing with a reasonalbe Christian on reddit 10-years back; Said African elephants were growing smaller, or no tusks, in response to poaching. He called it “breeding”. I call it hella selective pressure. Same difference?

                      The example of elephants producing less ivory for us to poach is unintentional selective breeding, yeah. Evolution works way faster when directed by an intelligence than when it’s left up to a relatively stable environment, simply because we exert more pressure for change.

                        i think also the concept of “survival of the fittest” was like an alpha thing; who fought nature and won. versus fittest being more about fitting into the environment better. the best fit for the specific environment.

                        “Survival of the fittest” has been around a long, long time and now we know better.

                          Nature can exert similar pressures without intelligence involved.
