Why Are Our Fingers’ Lengths Different From Each Other?

Our hands and fingers have evolved over millions of years to become what they are today. Of course, almost nothing emerged by chance in this evolutionary process. So are the lengths of our fingers.

If our fingers did not look like this, we would probably not even be able to establish civilizations and would remain at the level of other primates. Finger lengths are so important to us. how and when they diverge let’s see.

Our thumbs set us apart from other primates.

As humans, we have smaller fingers and palms than primates, but a much stronger thumb. This is our most important feature. As our thumb developed in the evolutionary process, to use tools We started learning, we gained fine motor skills, our emotional expression and communication increased.

It’s not exactly clear when our present-day hand form first appeared, but the oldest record yet discovered is 1.5 million years ago It shows that it is likely to endure.

Our hands resembled those of chimpanzees in earlier times.

The hands of our ancestors who lived millions of years before us; long fingers, wide palms and to a weak thumb had. So it was suitable for swinging from branch to branch in the trees. However, he was not strong or sensitive enough to perform actions such as holding a stick, shaking, squeezing, pinching.

So the first theory about why our fingers are different lengths is To make better tools, we need a better grip It depends on our hearing. It is thought that as we produced advanced tools such as axes and cleavers in order to survive, our fingers were also shaped according to this fine workmanship.

A similar theory has to do with our grip patterns.

Another theory is that our fingers evolved in different ways to throw or hold things with our hands. Our palms are smaller than other primates and our fingers are of different lengths, enable us to grasp objects better than them provides.

For example, an object We can pinch it between our thumb and our fingertips. or we can wrap all our fingers around our thumb. We can also say that it is the best grip method to grasp an axe.

It might even have happened just to make a fist.

Our only basic weapon that we can use only with our hands is the fist. Our fingers are inside while making a fist without any gaps It can curl. This occurs as a result of the lengths of the bones that make up each finger.

Our thumb increases the hardness during this punch. If our fingers were of equal length, we would do as much as we can right now. We couldn’t make a perfect punch. Of course, our fingers may have taken their current shape as a result of the combination of all these theories. Which theory makes the most sense to you?
