No "till", plenty of living beings have vestigial elements that were positive at some point of their history, yet no longer are, but are still maintained because there isn't evolutionary pressure to get rid of them.
The genes were from Neanderthals not to make them unattractive and they're also not vestigial. One is a very common gene related to blood clotting and can cause a higher risk of heart disease.
In other words, humans were fucking Neanderthals and we know it because of DNA. If they had never gone extinct it is without question the boinking would have continued.
I'm sorry, but this isn't correct, adult human females have breasts to hide when they are in estrus, by always being swollen, it's called hidden estrose, it's a whole thing. This has a lot of data backing it up. I KNOW I'M SPELLING IT WRONG! PROOFREADING IS THE LAST RETREAT OF COWARDS!!!!
The chin is situated near the area where the tongue and jawbone interact during speech. It's possible that the chin provides a surface for the tongue to move against, allowing for more complex sounds and articulations. The development of language is believed to have occurred around the same time as the emergence of Homo sapiens. While other primates have similar facial structures, they don't possess a distinct chin. This suggests that the chin might be related to the unique demands of human language.
Bingo -- other animals don't have a chin because they didn't invent languages like humans did for communication, and thus the demands of speaking weren't evenly distributed.
Next time on interesting questions 104: Why did homo sapiens develop language when other animals such as Corvids did not?
This makes more sense than the need to put on pillow cases (which has been my prevailing theory up to this point), but your question about corvids intrigues me. Partially because I'm not entirely certain of what a corvids is.
Corvids/Corvidae is a species of birds which include crows and ravens - they have demonstrated complex intelligence via tool use and social circles, so they're comparable to human intelligence of some specific various ages/milestones, but didn't invent a spoken language.
I read somewhere sometime ago that the theory that makes the most sense is that we evolved chins to take a punch, which animals besides our immediate evolutionary relatives do not do.
So we evolved chins as an evolutionary advantage over our immediate evolutionary relatives who would logically be competing for the same resources.
I read something at some point about how our fists seemed to have evolved or at least adapted to be well suited to delivering a punch. Many people do not use proper hand forms for it, but I suppose it's a learned skill if not at least through trial and error.
Great, now I have a scenario in my head where one early human delivers a punch and dies of having not the right hands and the other dies because no chin.
Also: Imagine our fists if there had been more habsburgs.
I'm a little shakey on the details but I think it has more to do with the extra bone mass in relation to the way the jaw functions. It acts more like a shock absorbing bumper than a lever.
Other animals that get punched there tend to take that blow more to the throat, which is a bit more problatic
You see a chin area yes, but it is simply the bottom of the jaw. The human chin has actual muscle that goes below the jaw bone and can be moved ever so slightly which aids in facial expression.
As bigfig said, your cat probably doesn't have a chin. That said, you might consider feeling your cat's chin to see if it's actually a chin and not just fluff or something.
If you feel a boney protrusion similar to a human's chin, then you should unironically contact an evolutionary researcher. They might be fascinated about your cat having an actual chin as humans and only humans (not even neanderthals) are the only known chin-havers. Who knows, your cat might be the "missing link" between chinned and chinless humanoids.
Many animals, including most felids and canids, have a fifth toe (aka dew claw), which could potentially evolve into a thumb. You don't normally see it on domestic dogs though, because if I'm not mistaken, it usually gets cut off when they're a puppy due to it being weak and having a tendency to get caught on things.
Alternatively, there is polydactylism in cats, which can give them extra toes that can help them grab things (I've seen a video of a polydactyl cat using it's extra foretoe like a thumb, though I can't find it). It seems possible that, overtime, an extra foretoe like that might eventually provide enough of a evolutionary benefit for it to become a standard feature.
If cats evolved human-like intelligence, they'd absolutely have night clubs of some kind. That said, I'm not convinced that cats don't already have human-like intelligence and aren't just choosing to not use it, but that's beside the point.
Walking bipedally is something a lot of smaller mammals can do as well, it just isn't their normal mode of locomotion because their bodies aren't currently designed for it. Going the evolution route again, however, and it's possible that a species might eventually decide to stand up like humans did. Edit: I forgot about birds, dinosaurs and semi-bipedal mammals like the pangolin. Birds and pre-historic theropods walked on two legs, and pangolins have heavy tails they can use to balance on their hind legs so their forelegs are free to dig at ant mounds. So humans aren't the only animals that walk on two legs.
The wing things are part of her clothing.
You're correct that being bothered by a chin alone is strange, but,
A) people have weird things that bother them, sometimes illogically
B) I kinda look at anthropomorphic animals as being evolved from their real world counterparts, so I tend to rationalize things in regards to how they might have evolved. It makes it more believable for me.
C) iirc, in the context of the movie that specific character is from, thats actually someone's VR avatar. As such, it makes sense to make human concessions like opposable thumbs, five fingers and toes (cats technically have five toes on each forepaw, four toes on each hind paw), walking plantigrade, etc. A chin seems like an odd concession to make. From the article, it doesn't really give humans any really evolutionary advantage so it's not like you're gonna be unable to do something because you don't have a chin; and based on what I've seen in the furry community, chins on anthros doesn't really seem to have much of an aesthetic appeal either (otherwise nearly every fursona would have an obvious chin).
D) It just looks weird. Idk man, it just looks weird to me.
That said, I don't tend to mind hybrids or mythical creatures like gryphons, dragons, dragon-cats, or whatever, so idk. It just looks weird to me and I guess the thing about humans being the only ones with chins is a explanation and justification for why I find it weird-looking.
I think this is plausible, also the fact that when you lean your head a little bit forward you expose the front of the skull which is the thickest part while the chin prevents people from punching your neck.
