Connect Your Thumb to Your Little Finger and You Will Reveal Something Special
The palmaris longus muscle
Put your arm on the table. Lift your palms, and connect the little finger and the thumb. Do you see your tendon? You can see it sometimes due to the palmaris longus muscle that is positioned between the wrist and the upper arm. This muscle doesn’t serve us anymore, but it is still visible in most of us. But the fact that it cannot be seen in around 13% of the world population is pretty interesting.
The wiggling of the ears
Have you ever met someone who has a cool party trick where they can move their ears up and down. Did you know humans used to wiggle their ears because it made their hearing better. In the ancient past, people needed to have great listening capabilities to be able to recognize certain sounds better. This helped them to avoid any possible danger. As we were leaving the wild, this predisposition was less and less used. Now it is only a tendency in cats and other animals that still have hunting tendancies.
Wisdom teeth
Have you ever wondered whats the point of your wisdom? More often than not we eventually have them removed, so why do they appear anyway? The answer to this is a long time ago, people had to chew a lot of solid foods and roots. That is why they needed stronger teeth and of course, more teeth would serve them much better. Today we eat soft food, so we don’t need so many teeth as our jaw is much smaller. There are changes even in animals. Monkeys today also don’t have wisdom teeth, except the gorillas.
Goosebumps
Did you know that the great amount of hair that people had on their skin, served them a lot? When it was standing straight, they felt warmer as more heat was supplied. It also helped them to look bigger and stronger when faced with some dangerous opponents.
