The carpal bones are the 8 bones that make up the joint between your forearm and your hand. Hand evolution is well documented - it’s a big research topic among Evo Biologists and Anthropologists. But I was curious to see if I could understand wrist evolution from my perspective.

Hi, I’m Patrick. I’m a freelance science writer based in the San Francisco Bay Area. I hold a bachelor’s degree in Athletic Training and a master’s in clinical exercise physiology. I used to work in the clinical setting as a certified athletic trainer, physical therapy aide, and a certified strength and conditioning specialist. After working in the clinical setting, I went back to school and became a teacher. The goal of my content is to help normal people, not just pre-med students, learn about the human body. That might mean explaining a topic from an anatomy class or exploring a topic from medical history.

This is the most underrated video I have come across on KZfaq 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. 😄

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.

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.

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.

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
@Corporis 3 жыл бұрын
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!

The first comment was actually a joke because there's always that one person that says "first."
