But there is one trait that undeniably shows proof of evolution
One truly remarkable evidence of evolution lies within our arms, specifically within our tendons. A tendon has been evolutionarily phased out in almost 10-15% of the human population, suggesting that we humans are far from reaching the end of evolution.
This tendon is associated with an ancient muscle known as the palmaris longus, which was predominantly used by arboreal primates such as lemurs and monkeys to aid in their movement from branch to branch. As humans and ground-dwelling apes like gorillas no longer rely on this muscle or tendon, both species have gradually been losing this internal function.
Nonetheless, evolution operates at its own pace – slowly, so nearly 90% of humans still retain this vestigial trait passed down from our primate ancestors. To check if you possess this tendon, place your forearm on a table with your palm facing upwards. Touch your pinky finger to your thumb and slightly lift your hand off the surface. If you observe a raised band in the middle of your wrist, you have the tendon connected to the still-existing palmaris longus.
