5 Times Evolution Should Have Planned Ahead

3 500 Shikime 355 mijë

Natural selection can lead to some pretty amazing adaptations, but sometimes the resulting traits aren’t the most efficient solutions to the problems at hand. With the bar set to “good enough,” here are some features that arose from evolution which get the job done in strange or roundabout ways.

    I always thought marsupials had the right idea in terms of reproducing. Give birth earlier and let it develop outside the body instead of waiting months and then trying to force a fully developed human through this tiny opening without dying. That's like putting together an Ikea bookshelf in your car and trying to push it out the window.

    I want to mention the koala. The island now called Australia was ones home to many more animals. Somehow less and less growed there and only the poisonous but strong eucalyptus stayed behind. Koalas started to eat the only thing they could find, eucalyptus leaves. Because the leaves are poisonous, has little nutritional value and is hard to digest, they could barely survive. Most indeed didn't. The ones who did were the ones that could conserve their energy best. The brain and the digestion system both use alot of energy. Even more energy was needed for the digestion so the ones with the least brainactivity survived. In just a few centuries the species has become so stupid they can't find a solution and or reverse it. They won't eat anything else and this stupidity would've probably been the end of the species if we didn't find them so damn cute and adorable and helpless. This is probably the only thing we as a human species try to save from extinction instead of pushing it to extinction without it being of commercial value to us.

    3:45 evolution doesn’t have a delete button ok, in a broader context, I might disagree (ie, early forms can be outcompeted by later forms), but willing to accept the point here. (ie, billions of years of chance mutation STILL have not produced a more efficient form of RuBisCo, so to some extent, you have to look at what’s biochemically possible). sudden thought: maybe better way to phrase the issue: “it’s hard to paddle upstream”?

    Love Scishow, always good for a laugh. The same old silly conjecture, scenarios, speculation that never happened, could never happen, been proved impossible. Not replicated in lab under ideal conditions that dont exist in nature, not observed. Natural random events will never ever produce complex molecules that get more complex. Only simple compounds, crystal, ores. Nothing remotely like life of any kind.

    The way I find it easy to think of is that evolution takes the path of least resistance. It takes the best immediate option but can’t take a detour. Just like how water flows downward only as long as it can. If you pour a glass, the water will flow out into the glass and stay there. Even though the floor would be a lower place for it to settle, it would have to detour up over the edge of the glass to make it there, which it can’t

    Isn't there 2 other ways of calling it? Inbreeding can cause mutations. The founder effect can cause the mutations to be prominent in the group. Then you have if it looks different enough it would be considered separate from the species that it evolved from. Basically think of it like creating a new dog breed, like the wiener dog. Then you have the mating bit, and if the mutations don't allow the population that has them to successfully mate with the original population. Then they'll try, and mate with ones with the same mutations that they can successfully mate with. Something like that I guess... There's also the adapting to the environment, but that's still on the lines of inbreeding... It just sounds better to call it as adapting, and instead of successful members inbreeding with each other. Or something like that.

    If I were making a designer human, I think I would want the cephalopod's forward-facing light sensors, and their light polarization detection ability, but instead detecting colors as they do using chromatic aberration, I'd rather have as many types of photoreceptors as a mantis shrimp. Also, in addition to eyelids, I'd like a bird-like nictitating membrane which acts as a contact lens. Also, bird lungs are awesome, I would want those too. When a bird inhales, air moves through its lungs from rear to front. When a bird exhales, the same thing happens! I wouldn't mind having a naked mole rat's resistance to cancer, and I wouldn't mind if my body could switch to a slow metabolism in the absence of oxygen, and if any of their DNA repair mechanisms are ones humans don't have, I would want those in addition to human ones. Oh, and let's not forget bonobos.

    Early hominids: "I need two structures beneath my torso which can be used to facilitate locomotion, without excessive risk of complication." Evolution: "Best I can do is take the manipulative structures you used to grab tree branches and lengthen them, make them slightly more sturdy, and compress all the little parts, while wrapping those little parts in an excessive amount of ligaments and tendons so they don't slip out." Hominids: "Will this hamper my ability to facilitate locomotion?" Evolution: "To a degree, yes. However, you will become able to run things to death, without ever having to touch them." Hominids: "And what will that cost me?" Evolution: "Considerable pain in the parts that weren't properly designed, deformation over time, and difficulty reproducing. Best I can do." Hominids: "...I'll take it."

    Can we all agree that the whole concept of a throat is just so terribly stupid? I mean, just connect this tube here and that one there, unnecessary choking hassard not needed!

    I always thought marsupials had an advantage because their pouches let them be more mobile, as they could carry their babies and not be tied down to nests or slowed down by young that might have trouble keeping up, or need to stop to nurse. However I've heard the tradeoff is less developed brains, so it's not that great after all.

    I do agree with evolution but I do also feel like we are missing a big part of the puzzle, it just seems there aren't enough bad examples of evolution in my opinion for it to be random. I'm not saying it's wrong but in time I think we'll discover DNA is playing a more active role or some such missing part, some king of genetic subconscious or something.

    Was listening to a podcast and they were discussing how some people think humans are the end goal for evolution. The guest they had went into explaining octopus eyes and the lack of blind spots so we can't be the peak of evolution XD I'll probably remember that for a long while

    sterility cannot be passed on but mother nature sure keeps trying for that one for some reason, much like the idea of gaming over the internet where the host server is on the other side of the planet.

    I love this episode. The way people talk about evolution always sounds like it has a plan, but actually things just exist or happen because they can. I feel like a lot of people don't realize that part.

    So, not only intelligent, octopuses are intelligently designed. Knowing this, I can't believe that people still eat them.

    My Dad's an engineer; a generalist, he starts from first principles, builds something and then it sorta works until he comes up with a better idea and then builds that. Littered about, among his 50 years of clients are the built things that continue to work, well enough, that are not the evolutionary high point of his skill My dad is, sorta, a god, yes?

    If humans have anything to do with genes, they're only keeping them "cuz they're pretty." I mean look at what people did to dogs. Surely we're doing something similar to ourselves without knowing it.
