If you haven’t heard about it, there are actually organs in our body that seem to be useless; and they are accepted as evidences supporting the Theory of Evolution. These rudimentary organs are called “Vestigial Structures”, and most of these organs have mysterious functions in our body.
Vestigial Structures in Our Body
Vestigial Structures are said to be remnants of our past evolutionary state where they are still fully functional. To better understand it, here are few of these organs that appears to be useless or only gives secondary functions to humans, but observed to be vital in our primate relatives:
Medical Sciences view the appendix as a useless tiny organ connected to our small intestine. Although studies show it acts as storage for good bacteria, appendix of other primates have far more obvious functions in digesting leaves.
- Coccyx or Tail Bone
Some scientists suggest that tail bone connects tendons, bones, muscles and other vital tissues in our pubic area. However, it is also observed in people who have their coccyx removed that they still have a normal life, and nothing was changed on their middle and lower body parts. On the other hand, it’s obvious that the coccyx connects to the tails of our primate cousins, which is highly important in their movement on trees.
- Ear Muscles
Ear muscles helps primates to move their ears to face to different direction, thus helping in their hearing perception. This is vital in their wildlife nature, but unnecessary for humans. Though we still have ear muscles, most of us can’t move our ears which makes such muscle useless.
There are still more organs in our body that’s considered to be vestigial structures. These organs have little to no use in our body, but is mysteriously present in our current evolutionary state.
