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.

5 Times Evolution Should Have Planned Ahead
3 500 Shikime 355 mijë
This lady is smart and pretty. That is not bad evolution. Keep going. We need super pretty, super smart ladies ASAP!
0:40 "The ones that survive wall banging are the ones that stick" Exactly!
Thank - you .
lol is that naruto on the thumbnail?
God damn girl get some f****** inflection. Pick up some personality while you're at it. Damn you're boring. You're so boring and monotone it hurts my brain. You belong as spoof material on channel awesome. Maybe you could have made Bart's nightmare let's play less irritating to watch.
Humanity as a species just needs a complete overhaul. Basically Homo Sapiens 2.0.
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.
The instant I clicked I knew RuBisCO would be brought up.
Honestly, I think marsupials have a pretty good. Sounds nice to only have a tiny bean slide out instead of a ginormous baby.
Maybe we may engineer our inheritance for the better. I would hazard a guess that human genetic engineering is being done covertly by various nations, this is a matter of concern if driven by ephemeral opportunism.
Yeah, thinking about it, it's weird. Wouldn't it be better if marsupials gave birth into their pouch?
Fun fact if you cut a giraffe by the bottom of hes neck the giraffes head will be send flying becase of the pressure
Wtf
Evolution: Let's see if A works... Nope. Let's see if B works... Nope. Let's see if C works... Yep. Go ye therefor and multiply.
Actually C4 isn't that advantageous in cold climates
OK, now I understand why my daughter was ready to change her Biology major when she took organic chemistry. I talked her out of it when I said "Good, now you can finance the rest of your education, and I can buy a Jaguar". She got a B+ and graduated. I bought a Nissan.
What doesn't thrive, perish (well, until humans decided to tamper with that.)
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.
If you have nothing more tan a pile of protein gelatin, not many tools, no plans, no schematics, and you are trying to fix the current problem, and on the top of that you are blind... Then you know how evolution works.
evolving from fishes was a bad idea
2:41 what no way evolution created explosives
Jesus christ our lord is infallible and only designed us wrong to punish us for our sins. Bullshiticus 69:69
The Flying Spaghetti Monster laughs at your folly.
man life is kinda jank
She's beautiful, naturally. Looks as if she may have indigenous ancestry. Being they all film in Montana, I'd say probably so. Her earrings look like Native artwork & jewelry.
Survival of the fit enough.
what about mermaids there has been many theories on them and possible sighting is there an evolutionary theory on this I wonder if are they just stories must be some explanations to this
To put it simply: they dont exist. Fishes arent Mammals, even if it could somehow live, there is no step in evolution able to make mermaids
People on pictures of animals: “ah, proof that god is magnificent!” Me: “okay but our eyeballs are backwards and our throat nerve takes an unnecessary loop around our heart.” Response: “I will pray for you, evil heathen who is destined to burn forever.” “...k thx.””
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”?
Kangaroos got their climbing selected for because Noah forgot to let them on the ark and they clung to the side...
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.
Translation: I flunked science, and hate the people who didn't.
Kent Hovind, is that you boy ?
Cool, I needed a bad opinion for a school project. Thank you!
Evolution does not have a trajectory -- it is driven.
Well it us efficient as, it works on its own
What if the human evolved from the marsupial branch ? This society would be totally different !
@chicken soldier Think of it, the gestation could be completed in a synthetic placenta freeing women ! Not to say there is no obligation of wearing a bra .Aesthetic is to be redefined with such a scenario.
Yeah, probably dead
Yeah, without watching this video, I'll say off the bat that evolution doesn't work that way. By it's very nature it's reactive, not proactive. I'm sure you are smart enough to know and mention this, but I'm not gonna watch to find out - basically because I may as well watch a video asking 'what if elephants could talk like humans?' or something else as impossible. ALfirst is full of these pointless question videos.
I don’t like this presenter
*Evolution making marsupial babies Fall Guys themselves to safety* Evolution: Its not practical, but its fun to watch.
Those last two about humans are funny considering those body parts only get damaged if you use them incorrectly. Lol
Our eyes not only have a blind spot, there is also large chunks of the brain needed to crop out the nerves and blood vessels from your field of view, so really horrible design.
I remember less than 5% mammals have monthly menstrual cycle. Though I am not quite the right sex to judge the inconvenience of this, that could've made the list ...
0:40 “The ones that survive wall banging” lol
Evolution - sponsored by Nike “ Just Do It”
if there is some cases where organs show evidence that they were not planed ahead , than that mean that everything else was planed ahead and that mean that it was not random but was designed intelligently in purpose and independently of what time or space circumstances are .
Perception of shame and ability to reach most part of body using hands were 2 things that gave apes advantage over other animals to evolve into modern humans..
Lol as soon as human bipedalism was mentioned I knew this was gonna be about our hilariously jacked up spines
"C4, as the name suggests-" Me: "Explosives." "-involves a molecule with 4 carbons" "Damn."
Silly scientists, it's all part of God's masterplan to trick us into thinking there was no plan.
Odin or Zeus ?
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
Evolution is lazy - it keeps saying mañana.
When you have enough/endless time, efficiency isn’t necessary. Inefficiency is a human perception.
So can I blame Australopithecus Afarensis for my back pain?
So basically humans are currently those giant, clunky computers that weren't efficient at all and will take a while before we get streamlined. Got it.
3 is totaly wrong the body just thought wouldnt it be cool if just yolo down to the heart and back those cells were in their rebel stages you know
You guys be talking sh*t about Mother Nature. She won’t be pleased.
Evolution throws everything at the wall... and sees what sticks.
So evolution is an Aussie - "She'll be right mate..."
So basically, evolution is a C student.
planned ahead? WRF...is this a fcking serious question. Holy fcking sht.
Gotta say I love your presenting style Rose 🌹 👌
The vertibrate eye actually has a benefit- the cells are shaped like cones, with the light sensor on the large end. The conical shape allows more to fit if they're backwards, so higher resolution is possible.
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.
C sections cause selection for narrow hips
Who was the speaker in this episode? She’s so pretty!
Wtf is a "Rose Bear Dont Walk"
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.
Evolution isn't about efficiency. Evolution by selection pressure is literally "just about good enough to not go extinct".
I think Neil Tyson said "humans breath, eat, and talk though the same hole in their head, and can do all three at the same time. Nobody would design that on purpose."
Natural selection is not natural at all. People made that up and so did animals. That is how much we understand life atm.
not means offensive... but she looks and sounds like a karen
I really like your delivery of subtle humour !
This is sounding like an argument for eugenics
great video, and very off topic but you look so much like Amanda Mcknight from top 10 nerd lmfaoo
What happens if you shorten the RLN?
While i was working for the post office there were many days where i wished i could swap my legs out for ostrich legs
I genuinely wonder what an alternative/more efficient structure for bipedalism would look like--
omg did they get rid of the ugly screecher girl i stopped watching these cause of her
Actually lots of evidence support we stood on two legs when we were still in trees.
Evolution: And there! Everyone: What the heck is that Evolution: Just some stuff I fixed Everyone: It's a ball of silicone and duct tape Evolution: Lmao yeah
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."
You didn't plan ahead?! Doom on you, doom on you.
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!
Christ that title...
Would we be able to walk up right if no one ever teaches us?
Kangaroo fetus is born for 5 seconds, first thing in its mind *PARKOUR*
An humans just breed willy nilly to hell with survival of the best genes be damned
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
Evolution gave all of us back and knee pain from the age of 14
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.
Cephalopods are pretty great: deep fried 😁
Nature's "if it ain't broke don't fix it"
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.
id say it’s pretty efficient most of the time and sufficient the rest but like you said, it’s about trait-lethality. love every one of your vids
So, not only intelligent, octopuses are intelligently designed. Knowing this, I can't believe that people still eat them.
Well written. Science with just the right amount of humor thrown in and intelligently written. Refreshing, thank you Rose.
C4 and CAM aren't an alternative to C3, it's more like another layer on top, a hack to get around the inefficiency of Rubisco.
lets evolve to immortal
Rose continues to throw up great videos; interest wise, research wise and research wise. Not to mention food for thought wise. Very much a great addition to the SciShow team.
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.
Good new presenter, welcome.
