The evolution human is still a matter to be widely studied by scientists. The discoveries over time have made science, on several occasions, alter in their records the concepts of how our ancestors lived. This information has helped us to understand our origins and to shape our steps towards the future.
Perhaps the most important change was getting up on both feet . Standing up left our hands free to do things that were not possible before. In addition to being a unique feature. Total bipedalism is a unique human characteristic. And even though he was good for evolution he also gave us problems. We show some of them here.
1 – Hemorrhoids
Walking with both feet gave a huge boost to overall health. The average human being is healthier than any of the monkeys. But this also led to health problems that would probably never go away. An example of this is hemorrhoids. They are common in half of all people.
Some people think they are a normal problem, but it is not. They are the direct result of the abnormal pressure made by the vertical structure of the body. And it is just one of several digestive diseases that humans have to walk on two feet .
2 – Back pain
The digestive system is not the only one that suffers from walking on two feet. Another problem, which came with the posture, is back pain. According to estimates, approximately 65 million people in the US alone say they have some type of back problem in a recent period.
Getting up left humans with their backs much more prone to injury, because that is not our natural state of being. Almost all people face back pain at least once in their lives.
3 – Loss of opposing toes
Having your hands free gave the brain an unprecedented cognitive boost. That’s because different levels of dexterity are needed for different tasks. And that gave us the ability to be better at hunting and to exert strength for long periods of time, more than any other predator.
But for that, we had to give up some skills. For example, from the opposite fingers of the feet. Of course, they are not the same, nor are they as versatile as the opposable thumbs, but they did give us some pretty cool skills. As the human being walked on two feet, they became obsolete and, at some point, disappeared.
4 – Easier to be detected by predators
As much as bipedalism has been a beneficial point for humans, the immediate benefits for the first humans are not so clear. One of the most disadvantages seen is that walking in the middle of the grass, surrounded by predators, has made humans much more visible. And that made primitive humans more susceptible to animal attacks.
5 – More prone to foot injuries
Like our back, our feet are more prone to injury, even because of the ease of twisting the ankle doing everyday things. As much as we need data to say that other animals do not also suffer from these pains, science says that this problem is not common to any other animal.
That’s because when humans left their four-legged life behind, their feet were unable to keep up with evolution so quickly. And they still have traces of flexible muscles and ligaments from ancient times. And since the feet are now just a basic structure for the body, they have regular flaws.
6 – Labor pain very high
With a quick look at the animal kingdom, you can see that females about to give birth do not seem to feel pain or discomfort. Most animals give birth as if it were a regular everyday thing. But this is not the case for humans.
And the reason for this is bipedalism. The severe pain that women experience during childbirth is due to the decision to stand, and this required the pelvis to become narrower. And this factor makes childbirth much more difficult for women.
7 – We get slower
In the speed aspect, the human being is worse than most animals. Even herbivores are able to run faster than us. Standing on both feet gave the human being ways to manage energy, such as the ability to cool off during physical exercise. And that made us give up on speed and agility.
