3 Signs of Evolution in Humans,
Tagged Under : evolution, humans, tailbone
In my last post, I mentioned the hind leg bones of whales as a possible sign of evolution. There are also clues from other species, such as humans, that could be used as evidence that species have slowly undergone evolution over a period of millions of years. As a devout Catholic, although I do believe in creationism, I also believe that the bible was not meant to be taken literally and that the theory of evolution could be accepted as truth. Here are three body parts in humans that could have been traces of our previous forms.
Tailbone - Also known as the coccyx. It is a set of fused vertebrae which is believed to be the last remaining trace of our tails before humans started to learn walking upright. Tails are designed to maintain balance for animals or even used to hang onto branches by some primates. For humans, a tail would essentially be useless given that we walk upright and do not need the tail for counterbalance. Our hip bones and muscles are the ones responsible for that. It is true, however, that the coccyx serves as support for minor muscles and pelvic organs, there have been no observed adverse health effects after its removal.
Body Hair - Alright, give me any seriously bad effects of being bald and shaving your eyebrows, armpits, or even your pubic hair. Can’t think of any? Of course. Aside from keeping sweat from going to your eyes (eyebrows) or helping deal with underarm moisture, the remaining hair on our body serves no other special purpose. Many scientists believe that it simply what remained of our once fully covered bodies but I’m still thankful. Otherwise, I wouldn’t be keeping this nice haircut I just had yesterday.
Toes - Admittedly, if we lost one or more of our toes it will be hard to keep our balance for a while. Eventually, it will just be the same as before. The truth is, the only toe we need for balance is the big toe. According to those who support the theory of evolution, the other toes were simply the remains of our history as tree climbers (like the chimpanzees).
There are other possible signs of us humans having evolved from other species such as a third eyelid and extrinsic muscles. If you are interested in the other ones, here’s a link for additional reading.
