Play posted:Evolution only works due to pressure on survival and reproduction. The organisms who successfully survive and reproduce pass down their genes while those who don't, don't. This causes incremental change over time as the successful genes are passed down while the unsuccessful ones aren't. I would be very careful with that second paragraph of yours. Not that there's anything wrong with it or that it's incorrect in any way. Just that thoughts like that can bring out the worst in people. Well not really, more like arseholes will use it as an excuse to be arseholes. That's why we need dicks! To gently caress those arseholes!

Pennywise the Frown posted:So even if our evolution is not helpful, wouldn't it still be evolution regardless? I suppose so, since evolution simply refers to "heritable change" rather than "successful heritable change". But it is definitely not natural selection and therefore is different from the evolution that all the other (wild) plants and animals have. Maybe it could be called genetic drift? I'm not a scientist

Well here's one of the first results from Science Magazine. I'm going to tend to believe these guys. https://www.sciencemag.org/news/2016/05/humans-are-still-evolving-and-we-can-watch-it-happen quote:Many people think evolution requires thousands or millions of years, but biologists know it can happen fast. Now, thanks to the genomic revolution, researchers can actually track the population-level genetic shifts that mark evolution in action—and they’re doing this in humans. Two studies presented at the Biology of Genomes meeting here last week show how our genomes have changed over centuries or decades, charting how since Roman times the British have evolved to be taller and fairer, and how just in the last generation the effect of a gene that favors cigarette smoking has dwindled in some groups. Also, the movie The Predator said some people say autism is the next stage of evolution. I get most of my science from Predator movies.

evolution is also a slow process and you're not going to see evidence of it in humans in your lifetime. we've just gotten so accustomed to the pace of the modern world people tend to get all "if I can't see it it must not be happening" okay guess I'm wrong but yeah evolution is constant

Also evolution is rarely helpful. It's not about killing the lion that is chasing you, it's about running faster than your buddy who's also running away. And maybe also tripping him up. And sleeping with his wife. And sending the sons you know were fathered by him off to war while yours stay safe and happy and gently caress his daughters. Survival of the individual, not the species. Your evolutionary advantage isn't a better lion-killing spear, it's a better lie to use when your buddy catches you in bed with his wife.

Pennywise the Frown posted:Well here's one of the first results from Science Magazine. I'm going to tend to believe these guys. No that's exactly what I was saying, those seem like pretty good examples of 'evolution' that is not related to classic natural selection. IronClaymore posted:Also evolution is rarely helpful.

And sending the sons you know were fathered by him off to war while yours stay safe and happy and gently caress his daughters. Evolution is literally just random genetic changes, most of which are entirely unhelpful, until eventually a helpful one comes along, helps its bearers procreate, and starts getting passed down. Anything related to successful procreation, whether its survival or attractiveness or different strategies to get that poontang, is fair game but its always incremental. It also works the other way, where organisms have evolved to look for certain traits in their sexual partners related to procreation. Most of the things people find attractive in women, for example, are directly related to successful procreation: big booties for child bearing, big titties for child rearing, and being young instead of old for successful birth.

I'd be, on average, fine with the human body but it has all these useless extra features like tonsils. Who the hell likes tonsils? They just sit there and do nothing except sometimes get stones which is disgusting.

That article states that humans change on a genomic level. Even if it has to do with breeding, that's evolution by the exact definition of the word. Here's the Smithsonian definition. quote:The process of evolution I think you're just moving the goal posts man. I'm not trying to argue but you literally said: quote:Humans have essentially stopped evolving in the traditional sense. So little actual pressure on survival, and whether or not you pass on your genetics is more about personal choice and social situation than having successful genes. There are still changes happening but they aren't really "evolution" as the world's animals and plants have it Evolution includes natural selection. Natural selection is something that drives evolution. Plants breed and evolve the same way. edit: I'm probably just misunderstanding what you meant.

I broke my pinkie toe a year or two ago and it really pissed me off because it's like, why is that even there? So stupid and useless, would be better if all the toes were just, like a flexible flap. Obviously a remnant from when we could actually grab branches and poo poo with our feet. Also had my appendix out, another evolutionary mistake/dead end.Pennywise the Frown posted:That article states that humans change on a genomic level. Even if it has to do with breeding, that's evolution by the exact definition of the word. I'm not arguing with you anyways! Just learning myself and exploring the topic in my head, if you want to call that moving the goalposts I find that kind of mean but go ahead. We're evolving, but it isn't refined in the same way it used to be. While we have a much larger genetic pool to elicit mutations from, which increases the speed of evolution, we also have very different pressures on the ability to procreate than a wild animal would have. Some pressures remain, such as diseases. So it is likely that resistance to diseases is one of the ways that humans are still evolving that IS actually related to survival. But probably one of the only ones since basically all genetic profiles except ones with serious innate diseases are capable of surviving and procreating. This kind of evolution is also going to have a stronger presence in poorer countries where procreation is more directly related to survival and success, and a lesser presence in countries like the US, where it definitely seems like we are evolving backwards. A good example of how evolution has changed is yours of humans getting taller and whiter in Great Britain. That has nothing to do with survival, I'd imagine it has to do with cultural preferences relating to attractiveness, although I don't know that for sure. "Cultural evolution" is an actual thing which has been used to describe this new, less survival-based kind of evolution. Play fucked around with this message at 20:20 on Apr 9, 2021 |

What the poster meant is that modern humans in developed countries do not face nearly as much selective pressures as humans historically/prehistorically have. This means that negative traits like a genetic mutation that means only one lung works or whatever does not have as much as an impact as it would have on the chance that those negative traits get passed on, because you can use technology to compensate for it.

I'm not a scientist I think, because of our huge population size and lack of strong selection pressures, we should be accumulating a lot of genetic diversity due to genetic drift, which is a good thing because if most the species started dying for some reason and we needed to evolve fast, evolution would have more variety to work with.

Anyway, the human retina is a big fuckup, it’s literally installed backwards. The light receptors are behind a layer of blood vessels and nerves, and light needs to pass through that layer first. There’s even a hole in the middle of your retina for your optic nerve to go through, and your brain has to fake some data in that region so that you don’t notice it. If your retina was flipped you’d have much sharper vision

Your boner isn’t pleasurable, your dumb body produces serotonin and testosterone when your visual cortex identifies an object as a body. It doesn’t have to be a real body, it can just be a 2d video on a screen, a still photograph, a computer rendering, a drawing, or many other things. Your boner is a lie.
