Our bodies are remarkable products of evolution, having transformed from creatures similar to chimpanzees into complex beings capable of creating societies and exploring space. Despite the rapid changes in the world, we are largely the same as we were 20,000 years ago, and we continue to evolve, though slowly and imperceptibly. One example of this gradual evolution is the palmaris longus tendon, which is disappearing in 10-15% of the human population.
