The theory of evolution, however scientifically established, is debatable. It has been questioned by the blind followers of the faith who say God has created man. This means man has not evolved from other living creatures.     

Notwithstanding the debate, have you wondered why do you get goosebumps when you feel cold? Why can some people voluntarily move their ears?  

Of course, the human body is a home to many untold mysteries. Evolution is one example. We all know who our ancestors were, where did we come from etc. Knowing more about our ancestors can actually help us in taking better care of our bodies.   

Some of our bodily functions are related to animals. Though some of these functions have turned out to be vestigial, most of us possess them.

Our jaw shape is inherited from apes.

Our bodies have few organs that are present as a result of prolonged evolution. These traits are called vestigial traits. This means those traits (such as organs or behaviour) that have lost all or most of their original function through evolution.

A little experiment.

Approaching it from a scientific angle, we look at it from 3 stages - Experiment, Observation, and Inference. Here's how you can trace your animal ancestry. 

Ready?   

Place your arm on a flat surface.     

The Observation

The Observation

Bring your thumb and pinky finger closer and tip your hand slightly up. If there's a raised band on your wrist, then it is a VESTIGIAL muscle in your arm!    

The Inference

The Inference

The lifted part is a tendon missing in about 15% humans. It's an organ present in many mammals who primarily use their forelimbs.   

It is called Palmaris Longus muscle.   

It is called Palmaris Longus muscle.   

It is present in the forelimbs of many mammals, most of them including primates. Though not having a significant effect in humans, it provides strength to forelimbs used for holding tree branches.      

Vestigial organs based on our ancestors.

If Palmaris Longus is present in the body, it means the ancestor mammals used forelimbs for their everyday chores more often.

The reason behind goosebumps also comes from animal ancestry.   

The Arrector Pili muscle. 

The Arrector Pili muscle. 

The function of this muscle is for defensive mechanism. When the muscles surrounding the hair contract in the cold, the skin above the hair follicle rises and creates a bump.    

This happens to animals too!

The raised hair increases the space for insulation against the cold. This occurs in furry mammals. This muscle is also responsible for the fight or flight situation, wherein the hair stand erect to appear bigger. This helps to intimidate enemies. A furry fox or a puffed up pigeon exhibit this behaviour.
