This Wrist Tendon May Be Proof of Human Evolution
Our bodies are “marvels of natural evolution,” yet we remain nearly unchanged from 20,000 years ago while living in a vastly different world.
A key example is the palmaris longus tendon, which is “gradually phased out in 10-15% of the human population.” This muscle, crucial for animals like monkeys to swing from branches, is becoming obsolete in humans.
Like ground-dwelling apes that lost this function, humans are “steadily phasing out” the tendon. Though nearly 90% still have it, this subtle change highlights how evolution continues—just very slowly.
