Our tails got cut off so we couldnt harness our inner oozaru, significantly cutting our combat power.
That is a great guess! We need to talk to your parents about upgrading you to our 'special class". Just joking. Although that did happen to me in elementary school.
Rip toriyama 😢
@@Tchado1000 😭
@@ryanreedgibson me, too, and I didn't know why, I assumed it was because I was such a problem child, and one for whom the condition was not relieved by growing up
@Tchado1000 how is this the first I've heard of this!? 😭 Rip akira
I took in a feral cat with no external tail. She was pregnant and she had a litter of 3 kittens. One had a tiny kinked tail, one had a medium-length tail, and one had a full-length tail. So between all 4 cats, we had the full spectrum of cat tails.
Some of the dominant genes that cause tail loss are variable. So it looks to me like the queen had it, and passed it to 2/3 of her kittens, and that one with the normal tail didn't get the gene from her at all. There may have even been another embryo in there that wasn't viable because she mated with another manx.
@@Aliandrin The cat was probably just mixed with a Manx. I'd venture to guess she may have been a slight bit larger or had unusual rear legs that were longer. Manx cats only have little nubs, naturally, and kind of have rabbit rear legs as well as being larger. Though, being mixed, this cat may have been small like a normal house cat.
I grew up with a bunch of Manx/Siamese mixed cats. It was funny, some were large like the Manx, while others were slight and lean like a Siamese. All were black from head to toe though.
@@Aliandrin
Or she did the deed with multiple toms with different tail lengths.
@@katnerd6712the cats most likely was not descended from Manx cats. Mixed breed cats are far more rare than in dogs, and breeds in cats are not really differentiated well at all. It was a random mutation to begin with. The possibility of it happening is in all cats. You’d be surprised what pops up in feral populations. When I worked at a shelter, I could tell you where most of the incoming trapped cats and kittens were from simply because of traits. I saw the same thing with a litter than came in. The ones with a shorter or no tail just randomly died, where as the longer length surprised. I believe only one with a 1/3 length tail made it to adulthood
Alternatively, the loss of a tail could be a congenital deformity, though that is more likely to come there’s signs like weakness or deceased feeling in the hind, bowel and urinary issues (up to an income lack of certain openings like the urethra dumping into the bowels or just missing entirely
If humans had tails they’d be spiny and fleshy; and let’s be honest with ourselves - lots of people wouldn’t clean under them properly 🤢
Might make mutual grooming a bit more spicy.
Ew lol.
Gross
Nooo you're right, & you know some straight men would think washing their tail was "gay" 😑
*_Septic masculinity._*
That's part of the trifecta of homophobia.
*_Cleaning ny butthole would be gay because it's a_** man's butthole.*
*_Being clean is feminine._*
*_Feminine things are inferior._*
If we had long fluffy tails entire industries would revolve around them.
Tail grooming, tail massage, tail coloring, tail hair extensions, tail decorations including tail scrunchies, tail exercises, tail based sports and of course tail porn.
There'd be _SO_ much tail porn. We really are randy apes.
Well, rule 34 with fictional races with tails from various media is a thing.
I suspect that the latter already exists. You can take any noun and add "porn" after it and it'll probably exist.
According to what a friend told me.
The latter DEFINITELY exists.
Nah, I think we'd be shamed into keeping them hidden, just like our other trouser-bound appendages. I bet some religions would have ceremonies where they dock or completely remove them from newborns.
So we can’t get YOINKED by the tail.
If only we had detachable tails like lizards.
Which is almost worse to think about than the hideous leather underside tail
But now we can't yoink WITH our talks either.
Gah that'd be so annoying. That'd be a good way to start a fight with me.

We lost our tails because Toriyama got sick of drawing them and it frustrated him to think how we'd put our pants on. RIP
"Go Toriyama. Teach a dinosaur to ride a ball."
We'd just have to have a gap for it with a button to fasten above it.
@@Weirdisjustabrownandyellowword and that button would be really awkward for sitting with! More like a flap or two with a button to the side so you/ your tail won't sit on it.
Pants would have a slit / cut our, or sit lower down. Easy.
@@Weirdisjustabrownandyellowword or we could just do what Sayans do in Dragonball and wrap them around us like belts
@@PaulXPZ But then the base would be twisted. Remember there are bones in there. It's not that flexible.

Only on this channel can we see actual pull-ups used in a primatology lecture.

"hideous leathery underside" is a funny series of words
I like leathery undersides, generally speaking.
the fact that a 30 min anthropology video has 122k views on youtube gives me hope for the world
in two months at that!
Now 123k.
141k views as of 26 Sept 2024. I grabbed this video as soon as YT presented it on my Home page, because God, how the hell did we lose our tails? What a fascinating question. The only thing missing was an explanation of the kind of fruits or nuts available to those who preferred a slow speed and needed a stronger 4-limbed grip strength. That food supply was superior to what the faster but weaker monkey species were getting? Like what? I hope to learn one day.
"What an impressive creature!" I laughed out loud and disturbed my dog.
me : *listens intently to learn new things*
my brain : *your thumbs are just tails for your hands*
My teenagers and I rarely agree on a show to watch. When they suggested Gutsick Gibbon I didn't know what to expect. Now I am super proud of them and this show is amazing. 45 and still learning. Love it. Many thanks.
I'm climbing on 49 and always love to learn something new.
61. Never stop learning, ever. The older you get it becomes one of the most valuable things that you can still do. I can no longer brachiate due to rotator cuff degeneration, but I can still learn; and so can all who desire to do so.

RIP to Akira Toriyama, creator of everyone's favorite prehensile tail-having hominin
Oh no, I missed the news about him.😢 Thanks for mentioning it.
(And unlike Goku, he's not coming back.)
Wait, really?! Oh. That sucks. 😭
L
Interesting that they only gained the ability to go super Saiyan after losing their tails. This correlated with a dramatic increase in their grip strength
How to spot somebody desperate for attention: They mention Akira in any way.
Stepping on your tail would definitely create panic at the disco.
It would probably cause world war 4.
I appreciate the extra effort you took to film your example ape in its natural habitat, rather than in captivity.
My 4 year old picked out this video for "The monkey butt", and we had a great conversation about all the different skulls and the animals they come from as a result. Super happy to see my kids curiosity and be able to answer questions from your video.
awwwww
I wonder if tail loss could be as simple as "if it's not being used, it's just bones and flesh that can be injured and become a lethal infection"? Appendages are a liability.
I was waiting for some statement as to whether tails were actively selected against, or, on the other hand, whether they were of no use, in which case, as lietz13 said, they become an appendage liable to infection and requiring food energy to maintain. All this video said is that they are apparently not selected against due to the development of bipedalism. But then what was the selective pressure that favored the survival of tail-less individuals?
And it has a caloric demand.
Keep in mind that i am in no way, shape or form a biologist, but i think it might just be because they were just getting weaker and smaller the more our grip strength grew, if we say that the information in this video is true.
If a primate would have more grip strength and mobility it wouldnt need to use its tail thus the tail would become very weak, which the opposite sex might view as some good mating material because the weak tail would indicate a strong individual.
But this doesnt really work with the proposal that the tails were kost from one generation to another. But maybe the loss of the tail was a mutation but these mutated primates grew to be stronger due to not havinf a tale, also leading to them mating more. Or maybe some combination of the two ideas.
Truly nobody knows but it is fun to think about. I dont even think having a tail would be that bad nowadays😂 too bad we lost them so long ago
"Appendages are a liability"
Reject ambulation, embrace bean.
Can we just give a shoutout to that ancient primate mom who had a kid without a tail and raised it up to be the best pre-ape it could be?🎉
I literally laughed out loud at the modern ape analyzing her own agility. That was F’ing hilarious! 😂

I love hearing Erica waxing poetically about primate evolution.
Because we put them down then got distracted by a butterfly and forgot where we put them.

My cat never tires of reminding me of my deficiency in this regard...
Hold him like a toddler and have him walk on his back legs. That'll show him!! 😂
are you kidding? one hand use the whisk, one hand crack eggs and the tail hold the bowl... sign me on right now!
Or one hand to use the vacuum, one hand to wrangle the cord, and a tail to move the kid away from something dangerous.
As a mom, I SO wish I'd had one when my kid was tiny lol.
Tails would be great for humans, but only after puberty. I don't want to think about the trouble our little ones would get into if they had tails.

The low branch suspension engagement demonstration was executed flawlessly
My geriatric microwave has sat in the same place in my house for over 2 decades. Whenever it runs, it inevitably smells of popcorn when you get close. Obviously, my childself would love to sit with my face in front of yhe microwave when it was running, to smell the tasty popcorn.
My parents tried to get me to stop doing this by telling me that I'd grow a tail if I continued. This did NOT work, as I was an animal-loving kid who thought having a tail would be AWESOME.
Needless to say, eventually I stopped sniffing the microwave, and I (unfortunately) have not grown a tail.
(This is little more than a comment for the algorithm, much love ❤)
I'd like a tail too. Tails are awesome.
Your palpable disappointment with the lack of a tail is hilarious. Thank you.
When I was a kid I always wanted a prehensile tail too. I think I just liked saying the word prehensile. But as an adult and a mother I think they would be really helpful. I'm sure they wouldn't be strong enough to hold a toddler. But they could maybe dangle something like keys to keep a baby entertained while I do other jobs.
Prehensile tails can support a mid sized monkey, so I would expect them to hold a bag of shopping. I too would like a tail please, if only for balance and emoting.
Hi Erika,
I just wanted to say that you're a great role model for young people interested in science, especially those interested in biology. I think that holds true regardless of one's sex, gender, race, religion, and creed. Keep up the great work.
I strongly suspect that if I'd had her channel as an influence on my life as a child, I would have been more dedicated to academia and more inclined to follow my interest in evolution perhaps even to a career related to evolutionary biology. It makes me very happy for any young people with the advantage of having access to her channel.
I've been practicing pull ups for a few months... hanging by only one arm is really hard I can't do it for more than a couple seconds! so indeed that ape in the demonstration is pretty athletic!
Yes, not every ape is athletic of course. Some of us training others don't...
I have an unfused coccyx from my mom's side that I can move ever so slightly by flexing the right muscles. It's incredibly saitsfying when the joints crack, but I can't do it on command no matter how badly I want to. From my dad, I got an extra lumbar vertebra. I'm 5'2" and my ex is 5'7", but we're almost exactly the same height when seated. My back is so long in comparison to my arms that I can't rest my palms flat beside me when I'm seated with my back straight. I got the weirdest, most pointless spine genes, lmao
At least I'm hyper-flexible to make up for my weird range of motion from my bones 😂
Wow, that's wild.
Gotta love atavisms in our genetics!
@Drachenfrau I've never actually thought about them all at once, but I do seem to have a curiously high number of basal features. My dad and I are unusually hirsute, and my mom and I have particularly long canines. I had mine "fixed" when I got braces, but dentists still comment on them. I've always been exceptionally strong compared to my very small size (but that could just be from gymnastics). My mom and I have always joked about our "monkey feet" and how good we are at grasping/manipulating objects with our toes. I have no idea how many of those things, if any, are actually caused by atavistic genes, but it's kind of cool to think about.
Sexy Stud, Show off"!",😜🤪😋🥰
I want a rat tail. Which are completely prehensile!
Rats just really underutilize their hardware. My girls only use their tails to grip when they both have no other option and are coaxed into remember they even have a thing attacked to their butt
9:40 What an impressive creature. This might be your best video ever. Thank you!
I think having a thick, leathery pink rat tail would be kind of cool 😂
why don't you ask the next big cat😮
16:13 *_Big-ass_** tail!*
My human evo professor, John Reeves, informed us that *_big-ass_* is, indeed, a technical term.
He teaches at the University of Akron and at Kent State (with Dr. Lovejoy).
No, no. That's a big ass-tail. Look again.
A prehensile tail would be pretty cool, but I'm still pissed off about losing the foot thumb.
Don't be. You wouldn't be able to run as efficiently.
So is Megan Fox a progenitor for a new clade or an evolutionary throwback?

There's a hilarious scene in one of the Hitchhiker's Guide books, where they have finally reached the Restaurant at the End of the Universe, and everybody there refers to Arthur Dent as a monkey. And in Buckaroo Banzai the Lectroids use "monkeyboys" as a racial epithet for humans.
You're such a goddamn good sport. Showing off your pull-up situation like that.
I wonder if "being a good sport" is somehow a major factor for success in life. I feel like it is
There are people who make entire careers out of refusing to take themselves too seriously. You might be on to something.
I definitely think people who take themselves too seriously are hard to teach.
Depends on how you define success. Most of the richest and most powerful people in the world take themselves way too seriously.
Life is literally a game! We literally evolved from dice! Not only is it only games all the way down, it's also only games all the way up! Genes brought us to the point where we can think for ourselves! Let's not go handing off all that power to memes right away! If that makes sense!
Look at a Punnett square. Look at a prisoner's dilemma chart. "It's the same picture"!
"Quit being a know it all. That's my job." But Erika, you're the ONLY source I've ever found that mentions we have tails! You ARE being a know it all every time I think "We DO have tails!" You're the reason I'm thinking it, haha! You're the one who TAUGHT me it!

Enjoying the new intro! It's a lot shorter than the old one 😄
Love the old intro but I'm so glad to see you're still experimenting and growing along with your channels statistical growth! So deserved! 🙌🏻
The length of the intro is probably related to how people nowadays consume content - if the intro is too long, people probably just click off. I've noticed this on a lot of channels, that previously had dedicated intros, - they either stopped doing them entirely, reduced their length or moved them deeper into the video.
I miss the old one. Can we have it at the back?
It got absorbed and is used by other functions. Longer introduction is unlikely to reevolve.
Algorithm strikes again. Perfect for keeping my brain busy while i do mindless stuff around the shop.
Being able to do a pull-up is pretty impressive.
"what an impressive creature" got a genuine chuckle out of me 😂
I wonder if our flexible shoulders were pre-adapted to throwing things.
I suspect an ape found it easier to throw things & the trait may have gotten selected for, because the ability helped them ward off predators & rivals, much like how Chimps currently throw rocks & wave sticks about to threaten rivals. It evolved first as a brachiating morphology, & the ability to throw stuff was discovered by an enterprising ape later. So not really "pre-adapted", but co-opted for other uses.
Or just hands. 👊

Love the "lifting part" but really just want show my appreciation of your knowledge and approach on the subject. Thank you and cheers from Sweden
no doubt you'll be wanting a fishtail😂
I read a book called “West of Eden” about a world where dinosaurs never died out. There was a species of human-like creatures that evolved from South American monkeys and yes, many of them did indeed have tails.
I saw the paper, and wondered if/when Gutsick Gibbon would cover it. I understood the genomics, but appreciate you giving us background that the authors did not address.
One problem I see with the "access fruit at the end of branches" idea, is that apes are significantly larger than monkeys. This seems to contradict the idea that they are specialized towards accessing the tips of branches. I am curious about the selection pressures, specifically of orangutans, that caused them to become the largest arboreal animals ever.
but....we've observed gibbons and orangutans, etc doing exactly this. hanging from some large branches to pick fruits and nuts of nearby smaller branches. she even showed a photo of a gibbon doing this multiple times
Erica, because I love you so much.
The name "Xia" is pronounced like she + ahh, but only one syllable. In Yale Romanization it's "Sya" The standard Mandarin "S" always leans slightly toward a palatal "sh".

You should honestly be a voice actor!!!! Very unique voice! Thank you for the video my virtual friend. ❤
I’m salty that we don’t still have those sick grabby feet
i can write with one of my feet, looks like kindergarten handwriting, but thats because i dont practice. its fun.
Seems like tails and hand feet would be advantageous… Wonder Why “Bipedalism” arose… Maybe some single~generation, Magical “Chromosome Fusion Event?” 😆
They're great for clambering about in trees, but terrible for walking upright on. The way the thumb jointed to the hand would have to change, somewhat. I imagine how they're structured now would make for a raging case of arthritis when we're older if we still had them.
@@SeaScienceFilmLabs Unlikely. It's more likely a slow change from occasional bipedal locomotion of a brachiating ape to fully-terrestrial ape. Going bipedal on the savannah was likely more useful: it allowed us to see over the grasses & watch for predators.
@@DrachenGothik666 I agree, it is “Unlikely.” 🤣
Human Evolution is a joke.
Yes...definitely agree....if we're going to have tails, they sure better be prehensile!
I love how you put "we" in the title just to annoy people LOL
I’m with you on the prehensile tail. I’ve wished since I was 13 we had big puffy tails like a skunks that is also prehensile.
We’re in the wrong timeline.
Fascinating! Gibbons were always my favorite animal at the zoo because I loved watching how they move. I never realized the other monkeys move on top of the branch, which was why I was drawn to the gibbon.
I love these videos focusing on primatology and also love the new intro
Thank you for educating me during my workout today! Your pull-ups happened to be perfect since it's back day. Gains in mind and body, get it!
she couldn't do a pull-up to save her life, no doubt you think lifting, a piece of steak to your, eating hole condemning the poor animals flesh to your gut bag it's a workout😂
I want my tail back.
I'm so proud of you talking about an historic " professor subject" in a well informed way. You have done your homework and set up a great presentation before you started. Hope in your near future you can become a biologist or a biological teacher. Best wishes for you and your future.
Let's start a gofundme to get you a tail.
I for one think her tail's just fine now...
Without diving deeper into this topic and just from my logical thinking, the main reason for the loss of the tail must be size.
When a primate becomes big, the tail can no longer function as a 5th limb and looses it's advantage.
Additional reasons are ofc moving away from living on trees as a habitat.
@Gutsick Gibbon, Love the new intro!
in very rare cases, humans can be born with a "tail." the pictures that I saw were very thought-provoking. I wonder if their genome were examined.
I'm surprised creationists don't still have tails.
What an impressive creature indeed, I can tell I have much to learn from this ape specimen. Thank you for illuminating this subject for us, and so eloquently!
9:18 Definitely an impressive creature!
First time I’ve seen one of your videos and I thoroughly enjoyed this! I love all the actual science as I am a doctor who has always had a love for evolutionary physical anthropology. Can’t wait to watch more videos.

Erika: "I wish humans still had tails. That would be pretty awesome!"
Camera: "Absolutely! I agree!"
This is a rather interesting video to see released the same day that it's publicly announced that Akira Toriyama, the creator of Dragonball, had passed away.
Not in a bad way, mind you, it's just making me feel weirdly maudlin.
Forget the tail, I wish we had 4 hands.
Like in Aeon Flux 😆
Aliens! Pyramids! Atlantis! Something something...
Ok
Anubis!
I guess a large distinction between us and the other apes is that we are a lot weaker.
I love your channel I learn so much and am currently in college because of you and Forrest Valkai! I bought the Gutsick gibbon phone case and I absolutely love it!
I think we lost our tails because we kept sitting on them. Rocks, logs, and the ground can be hard... 😖
In all seriousness, though, I'd expect the loss of our tales to be related to the biomechanical demands of our ecological niche prior to our role as a dominant species and the impact of our growing size on arboreal lifestyles. The grip strength theory seems plausible to me but I expected this to be well-known already because humans continued to adapt to stretching for outer branches' fruit as we got heavier and likely came to rely on more upright positions in trees (as we became less mobile in them).
As humans transitioned towards being an endurance running predator, the tail could have been a potential source of inefficiencies and diseases. I think this would strengthen the loss of tails and help keep them gone.
Prehensile tails take a bunch of energy and we already need a lot to power our brains as well
