Mysterious riddle you know: Why do people have butt? - Photo 1.

What makes people different from all the rest of the animals on Earth? Is it our wisdom? Big skull size? Do we stand up straight with our legs? Or is it simply a sexy and charming butt?

All right! And you don't misread, humans own a bigger and unique third round than all the rest of the animals on Earth. It is a round buttock, floating blocks full and soft.

That buttock was "squats"During the evolution that lasted 350 million years, to become a masterpiece like the present. But what is the purpose of the butt? And why is our butt shaped like that? Let's find out:

Maybe you don't know: Why do people have butt?

The structure that we call butt, actually consists of the main muscles: gluteus minimus (small gluteus), gluteus medius (missed gluteal muscle) and gluteus maximus (big gluteal muscle). Of these three gluteal muscles, gluteus maximus is the one that will be responsible for your buttock shape.

Big buttock muscles originate from a strip running from the pelvic area that people often call hips, down to the coccyx. At the bottom of the muscular bands converge and stick to the top of the femur.

Big buttocks are muscles that control the main stretching of the legs, when we run, climb stairs or need to stand up while sitting … Something, any activity that requires your feet to move quickly or change your posture, your buttocks will be responsible.

That's why sprinting and squats will help you get round and firm buttocks.

Keeping such a heavy task, buttocks have to create a lot of force to make our feet move. But the limited space from the pelvis to the femur bone does not allow it to grow in length.

The gluteal muscles are forced to develop in many horizontal, large, and thick layers. Swept in the direction of gravity, the gluteus maximus muscle bundles flow downwards and create a butt shape for you.

Buttock groups, only in humans, new gluteus maximus

In fact, the human buttocks have the most unique shape compared to all other mammals. As we evolved from gibbons moving on all fours to modern people with two legs, our pelvis undergoes radical changes to help with the weight of the entire body that lies on it.

This requires significant hip orientation, and it also puts big butt muscles in the strange position you are. Under the anatomical snapshot, almost your buttocks hang completely out of your pelvis.

There are a few other mammal species that look superficially, in particular horses. However, the development of their buttocks did not come from large buttocks, but the enlargement of the gluteal muscle group. Pretty many mammals have buttocks, also from the development of this gluteal muscle.

Humans are the only species that develops large buttocks. It is certainly an arrangement of creation, as we evolve into a unique, unique and two-foot walking species.

Some mammals look superficially, but only human butt is unique

Yes, the story will be even more appealing, if we look at the evolution of animals.

About 350 million years ago, the first four-legged animals walking on land began to appear. They all have big tails. One of their tail muscles, called caudofemoralis, connects the tail to the femur.

When underwater, this muscle was used by their ancestors to swim. When going up, the animals used their tails to pull their hind legs backwards, thereby pushing the body forward. Imagine the gait of Tyrannosaurus rex tyrants.

During evolution, the tail muscles are still retained by many later animals, which even persist today in some groups such as reptiles and amphibians. These animals often have long and large tails, as they depend a lot on the tail muscles to move.

Even so, not all animals want to waddle forever like crocodiles. About 300 million years ago, a group of animals called synapsids, the ancestors of mammals, evolved in a way that eliminated the importance of the tail.

The first terrestrial animals use tails to stand and move

They develop a muscle that replaces tail muscles for movement and movement. As you can guess, it's the gluteal muscle. These muscles connect the hips to the femur that are completely unrelated to the tail muscles.

Over millions of years, their tail muscles are getting smaller and smaller. About 200 million years ago, mammals were almost only very small tails. They do not contribute to travel. Instead, the task is shifted to the gluteal muscles, making the buttocks grow, increasing in size and forming blocks.

Until about 6 million years ago, when human ancestors began to stand up straight on their legs, these primates stopped using their forelegs to move. They rely heavily on the hind legs to stand and walk, move.

This transition means all the power needed to push the walking process, now, is placed solely on the gluteal muscle. No other option, the primate's buttocks with two legs must increase in size and float into a mass that is larger than the pelvis.

In addition, a few fat pads are also placed alternately into the buttocks. It keeps the muscles from getting hurt when rubbed against the hip bone. These fat muscles and pads make up your buttocks now.

In parallel with the growth of the brain, our buttocks are also larger after evolution

These are the reasons that you will never see buttocks, as well as many other mammals.

Even in primates they are close to us like gorillas and chimpanzees, their buttocks cannot be as big and charming as humans. The reason is because these animals only move with their legs in shorter periods of time and are still familiar with the whole limb.

Moreover, they don't know squats or sprints like humans. And that's a little trick for you. If you want your buttocks to become bigger and sexier, practice exercises that require posture changes or fast leg movements. That's when your buttocks are used and most developed.
