In the first chapter of The Descent of Man, Charles Darwin identified roughly a dozen body parts that he gleefully described as “useless, or nearly useless.” Darwin’s catalog was far from complete — our bodies are littered with parts we don’t need. Let’s have a look at some of them.
Scientists found that humans used to walk and balance more on the mid line of their feet, but now we have gradually transferred to balancing more toward the side of our big toe. Studies also show that our center of balance is still shifting inward. This means that humans used to rely on their toes for balance, but now they don’t rely on them as much. If this trend keeps up, we will no longer need our toes. Source:BrightSide
