People have not ceased to grow. Although many changes occurring with the man invisible, over time, many of them show up in full force.
We are still subject to natural selection, despite the development of modern medicine and technology.
What sort of features we have in the distant future, based on current trends? Here are the 10 biggest changes that may occur in a few hundred thousand years.
The development of modern vehicles and communication leads to the fact that fewer people are isolated from the others. Increasingly, there is a mixture between the races, whose ancestors came from different parts of our planet.
As a result of the genetic differences between people are beginning to fade, and racial differences become less noticeable . In other words, people are more future alike.
2. Compromised immunity
As soon as people become increasingly dependent on drugs for survival, our immune system starts to weaken.
People of the future will be more susceptible to pathogens . Modern medical technology and the discovery of antibiotics to improve our health and life expectancy, but has led to the fact that our immune system has to work less to maintain health.
From the point of view of biology, our immune system is not as necessary as it used to and we will be even more dependent on medical technology.
3. Muscular Atrophy
Evolution gets rid of those signs that are no longer needed. One of the candidates for elimination in this sense is a physical force. People no longer have to rely on strong muscles to perform time-consuming tasks. We are increasingly dependent on technologies that perform for us this work. Studies have already shown that we are much weaker than our distant relatives , and in the future may become more frail.
Furthermore, if we begin to explore more and more other places in space, then most likely lose most of our muscle mass . Astronauts who have been in long-term space flight, returning to Earth, having lost the capacity for physical work by 40 percent.
4. High growth
Human growth over the past two centuries has increased rapidly. Only in the last 150 years, man has become an average above 10 cm . It is believed that the main reason for this is the abundance of food available to us.
The more child eating, the more energy he has to increase. As long as people are able to have a surplus, we will continue to grow even higher. Is there a limit to our growth, show the evolution.
5. Little Hair
People are already calling hairless apes. However, like all mammals have hair we have, but they are much smaller than our anthropoid ancestors and relatives.
Clothing and modern technology has made warming feature hair out of date. Women are considered to be more attractive without hair in certain parts of the body, and perhaps with time, there will be no hair at all.
6. There is no wisdom teeth
Established reason removed wisdom teeth is that most modern people jaw is too small to accommodate them without interfering with the other teeth. They are considered rudimentary molars that have emerged from the ancient people when their jaw was more food and consisted mainly of hard food.
Not surprisingly, the wisdom teeth begin to fade. Furthermore, 35 percent of people are born without wisdom teeth , others have only one, two or three wisdom tooth (total of 4).
In addition, our teeth will become even smaller. Over the past 100 000 years ago, our teeth are reduced in size by almost half, and this trend may continue in the future.
7. Memory impairment
Technology has affected the way our memory works. The human brain, being a machine that seek to maximize efficiency, usually remembers where information is stored, rather than the information itself.
In the age of the Internet, this feature has become more important. How often have you tried to remember something and instead just watched the answer on Wikipedia or search engine? The habit of checking all the Internet has taught us to use the computer and internet as "external memory" , eliminating the need for our brains store information.
8. Less toes
Before people learned to walk upright, our toes used for grasping, as well as hands. As soon as we began to climb less and walk more, our toes began to decrease to the current size.
At that time, as the thumb support balance and helps with walking, from the little finger there is some special purpose. Perhaps for this reason, over time, people become creatures with four toes .
9. Larger or smaller head size
Scientists are still debating whether a person will in the future have a greater or lesser volume of the skull. Most of the opinion that a person can not develop a large head, since it is impossible to make natural childbirth, and increase mortality in mothers. For this reason, the size of a person's head is likely to remain unchanged, and may even decrease.
But it is worth considering the fact that a growing number of caesarean sections allow children to survive with a large head. Many even believe that over time, a cesarean section will be safer natural childbirth, and children with small head, born naturally, will be less likely to survive than those whose mothers have gone through surgery.
People can reach the stage where they will be able to manage the evolution of man through technology.Bionic organs and genetic selection will allow prospective parents to choose the characteristics of the child before birth.
This can eliminate all defects and undesirable characteristics . Once such a practice becomes common, it can lead to the disappearance of many negative attributes.
How will the people of the future?
That's what some experts to change our body and face thousands of years:
- Height of about 180 -210 cm due to better nutrition and progress in medicine
- Over short gut to absorb less fat and sugar and prevent obesity
- The smaller size of the testes due to lower male fertility.
- Over the long arms and fingers to spare us from having to reach for objects. More nerve endings on the fingers to use various devices such as iPhone.
- The smaller the size of the brain due to the fact that the problem of thinking and memory in computers basically operate.
- Big eyes will compensate for a small mouth. Communication will be based on facial expressions and eye movements.
- Less teeth , as food becomes softer and does not require much chewing.
- Quadruple chin due to the fact that our bodies are designed to eat less and use more energy than it is now.
- the same shape of the nose , as the climate is less effect on the body due to the air conditioning and heating facilities.
- Less hair or baldness due to the use of warm clothes and heating means, but more wrinkles due to the use of electronic devices.
- sagging skin on the neck and bags under the eyes due to the strong influence of the sun.
- darker skin because of miscegenation.
