How Humans Got Their Wrists | Corporis

[@billy2896]

Dude, please never stop making these videos. They are amazing, and the algorithm isn't giving you the attention you deserve.

[@Corporis]

Glad you like them! And that's the plan -- keep going.

[@mohammedquadir9490]

I am a biology student. Your videos make my free time fun and productive. Your videos are work of art. You deserve more views.

[@Corporis]

In school I always pronounced it "piss-ih-form". Turns out it's more like "pizza-form". The more you know!

[@apocalypse487]

Lol, I'm glad I'm not the only one who thought that.

[@DJDCann]

This is the most underrated video I have come across on KZbin to date. 40 hours of work into a video touching locomotive grouping and benefits to wrist anatomy in humans and near ancestors. The EvoDevo bonus too. 4,604 views is insanely low. I have a feeling the algorithm will bring wider light to this in the future. 😄

[@theGouramistOnline]

this dude is motivating me to study anatomy

[@Corporis]

Dude, that means a lot, thank you. And best of luck in your anatomy studies

[@notlisztening9821]

You have a very authentic way of speaking and presenting yourself

[@pghparkins]

Man, this has me pondering like crazy. It really goes to show how complicated our path to modern form was. I guess there could have been a style of human that could throw spears but there were probably individuals with some of these mutations that let them throw spears better or position them better in their grip. They were better at bringing home the bacon, so their station in the group would be higher, meaning more opportunities to procreate. The more we evolved to be social, the better chance of positive traits had of being passed forward, including more sociability. It'd be interesting to ponder the idea of what mutations do we see today that would be advantageous should humanity suddenly be collapsed into a small cohort.

It’s super impressive how much knowledge and effort are put in this video! You’re awesome Patrick 🌻 I hope your channel gets the attention it deserves soon🙏🏻♥️♥️

[@Corporis]

Thanks so much Maryam! I hope the social media break is giving your brain some deserved peace!

[@nikevisor54]

Dear Algorithm, Please feature more Corporis in the Recommended tab. Thank you. Viewers

[@apocalypse487]

Give it a thumbs up. That's what helps with the algorithm

[@Corporis]

I appreciate you all. thank you

[@aksharchug]

Thanks for upgrading my knowledge...😀

[@Corporis]

Always welcome

[@maya14333]

Great Video 👌, Thank you for sharing your knowledge. My only problem is why your channel is underrated. Hoping for the success of your channel.

[@Corporis]

I appreciate that! Thanks for the kind words

[@AquaticIvy]

I’m in PA school and we just finished our unit which included structures of the wrist and hand. Super interesting to learning about how everything got there.

[@MindfulAttraction2.0]

Dude this is so awesome!

[@DrMattDrMike]

Awesome as always!!

[@Corporis]

Cheers guys! Thank you

[@chickenpickle131]

This channel is awesome. I can't stop watching it

[@Corporis]

Glad you enjoy it! Thanks for the kind words

[@aakashpandit2002]

And... Amazing work again...Hoping to see more evolutionary biology videos.

[@S0ft]

I genuinely love your videos so much, thanks to Medlife Crisis I've become such a big fan ♥️

[@Corporis]

Glad you like my work! I'm a big fan of Rohin as well, so I'm excited you're here

[@lancefreezeify]

Thanks for such high effort videos! They are always so entertaining and informative.

[@Corporis]

Glad you like them! Thanks for the kind words

[@edvardstreijs9083]

Does the line at 5:38 show the trapezium bone instead of the scaphoid? Great video though!

[@CoelusGame]

So you’re saying that my ancestors aren’t Adam and Eve, instead they’re chunky salamanders

[@Corporis]

*Chonky* salamanders

[@georgf9279]

¿Por qué no los dos?

[@TheNarregg]

Hey, first off, I really like your videos, they are well done and you keep them interesting. But I´m a bit of a nitpick when it comes to anatomy, sorry. At 5:38 you are pointing to the trapezium instead of the scaphoid. Edit: Changed trapezoid to trapezium, english isn´t my native language xD

[@Corporis]

I appreciate the catch! As you can imagine, there are a lot of moving pieces during animation and glitches like that arrow happen from time to time. Yes, you're totally correct, I said scaphoid but pointed to a different bone. Thank you!

[@TheNarregg]

@@Corporis That´s what I thought, that it was just an animation error. Keep up the good work. Evolutionary anatomy is very interesting and helpful to understand why anatomical structures look the way they do, sadly my university stopped teaching it.

[@Camboo10]

I learned ricochetal brachiation today. Now I'm off to annoy my friends.

[@Corporis]

If you took anything away from this video, I'm glad it was that.

[@Phreemunny]

Our knowledge of what allows the dart throwers motion (movement at the mid-carpal joint; movement of the distal row around the proximal) is relatively new (within the past decade). Before that, it was assumed that the joint was relatively stable, and that most of the dart throwers motion came from the coordinated flexion, extension, pronation and supination of the carpals. The fact that we don’t know exactly how or why this evolved the way it did is not surprising, given how recent this knowledge is. Given what we believe about the importance of introducing animal protein into our diets in producing a more robust frontal lobe, as well as a body generally poorly evolved for catching and killing animals for food or for defense without tools, and the need to do so at a distance, in order to prevent injury, it seems entirely plausible that this wrist structure came about entirely out of a need to throw a spear-like object. (Keep in mind; a larger frontal lobe means a weaker mandible, so we are shit at biting to protect ourselves or kill prey.). This seems to me to be an entirely strong enough selection pressure.

[@pghparkins]

Here is a free idea for a new sci fi novel. Right now humanity basically gets to pick the best of the best when it comes to certain traits (mental toughness, intelligence, physical toughness) to be astronauts. Now imagine we are colonizing another planet, we would almost certainly lean towards those types of people. I wonder how many generations it would take for them to become drastically different from humans on earth. I mean, I guess the Expanse sort of did that with the Belters, but that was more environmental. I am thinking specifically about certain traits. Of course the environment would reinforce it as well. I dunno, I am rambling, but this video really got me thinking.

[@maureenkelly738]

Great video!

[@chestersnap]

I spent most of this video just staring at my hand and moving it around. I now really want to know how the wrist helps us make those motions. Also, at one point I was way too amazed by the fact I can hold a baseball

[@Corporis]

Amazing. I'm putting "at one point I was way too amazed by the fact I can hold a baseball" on my resume.

[@abouttoanimals]

Informative ❤💙💙❤

[@kezzyhko]

"So underrated channel, only 43 views?!?!" I first thought, and then looked at other videos Well, 1K views is still too few for this channel IMO

[@Corporis]

Thank you for contributing at least one of those views. I appreciate it sincerely

[@Troy-ol5fk]

Learned a lot

[@corwin32]

This makes me think of the Animaniacs’ skeleton song 🎶The finger bones are numerous 🎵The upper arm’s the humerus 🎶The forearms got two pieces names the radius and ulna

[@Corporis]

Ohh man, I miss that Animaniacs sense of humor so much. Pinky and the Brain was my favorite as a kid

[@marinacam2755]

@@Corporis they’re pinky and the brain they’re pinky and the brain, one is a genius, the others insane 🎶 funny how that is stored in my brain as soon as I saw pinky and the brain mentioned

[@apocalypse487]

iM fIrSt! Thanks for posting these videos. It's hard work.

[@Corporis]

I started this one back in July! Lots of work indeed. Thanks for being getting here first!

[@apocalypse487]

@@Corporis Wow, that's a long time. It was precise and informative. I knew the hands and feet were physically different, but not this different and similar at the same time. I've never had any teachers that could explain like this (except my high school physics teacher and history teacher). The first comment was actually a joke because there's always that one person that says "first."
