10 Human evolution which are still in progress!





Historically, the birth process has limited the size of the brain, because the babies have to pass through the birth canal. Today, however, cesarean procedure bypasses this process. Pobiner notes that more than 46 percent of children born in China, are born through caesarean section. What happens with natural selection, taking into account developments in the field of fertility and improve post-natal medicine? The number is constantly growing population of the world, and the people themselves are actively developing. However, with an increase in sea level and decrease the amount of space available for housing, various diseases is much easier to spread.

           The largest virus ever found was a virus that had existed under the permafrost, known as Pitovirus (Pithovirus). While this particular virus is not dangerous to humans, what happens if the "thaw" dangerous to human life parasite? For example, according to the World Health Organization smallpox virus was eradicated in 1979, but some experts say that succeeded him deliver only the surface of the earth, but it could survive in the frozen form. human evolution is saved in other areas, such as sexual selection. A recent study found that beards are becoming more attractive as the number of carriers in the population decreases significantly. Experts have found that when the time period of "peak" their popularity has started to fall. Economic conditions may also influence the desire to wear a beard, because as unemployed or malozarabatyvayuschie men can grow it as a sign of masculinity, they can not emphasize financial security. So what is the answer to a question about human evolution? "As long as man exists, it will evolve," - summed up Pobiner.

 Unnecessary parts of the human body 


1) Goosebumps 


we covered ants, when we are scared, cold, we are excited or angry. Other representatives of the animal world are covered with goose bumps for similar reasons, that's why the cat fur, for example, becomes erect. When it's cold, elevated scalp do not allow air to "go" from the skin, thereby keeping heat. When scared, raised fleece helps the animal look bigger than it actually is. Man does not need these properties, but they haunt us from the past, when people who have been so frightening. That is, the process of natural selection put the wool, and the mechanism has not yet managed to eliminate.

2) The VNO 



This amazing body talks about the evolution of our sexuality. It is located in our nose is the olfactory processes and detects pheromones. With the help of some animals find a mate, as well as calculate the danger. The man still comes into the world with this body, however, it is still at a very early stage of development of people's need for it anymore. Today people use more effective methods of finding your partner.

 3) Junk DNA 


In the human body contains the genetic mechanisms, which at one time to produce enzymes for vitamin C. This DNA works in most animals living today on the planet, however, in the history of human evolution she has been locked at a certain stage. This junk DNA suggests that all species on Earth have a common origin.

 4) Additional ear muscles


 Animals used ear muscles to control their ear. They turn them to concentrate on a certain sound. In humans, these muscles are also present, however, they are almost atrophied. Very good additional ear muscles are developed in cats.

5) Plantaris muscle


This muscle is necessary for animals that pick up and use objects with his feet. This can be observed in monkeys. In humans, it is also there, but it is much less developed. Often it used by doctors when they need tissue for reconstruction of any part of the body. Plantaris muscle - a vestige of the absolute: more than 9 percent of people are born without it.


 6) Wisdom Teeth


 Main food of early human ancestors were of vegetable origin.Plants had to be eaten quickly and in large quantities for the body received the proper amount of nutrients. That is why the ancient man was another set of molars, which accelerates the process of chewing food. This was important, because the body of our ancestor was not able to fully digest cellulose. However, with our food system has changed over time, his jaw dropped, and wisdom teeth were out of work. Some people do not know what it is, while others continue to suffer.

 7) Third eyelid



 Observe how the process of Blink the cat, and you will notice his eyes white membrane, which is the third century. Among mammals, this feature is quite rare, but it is characteristic of many species of birds, fish and reptiles. In humans, the third eyelid is also there, but it greatly reduced in size.

 8) Darwin's tubercle 


This part of the body is in most mammals, man is no exception. Tubercle has been designed in order to better capture the sounds, but people no longer need this feature. This feature has not everyone. According to some reports, it is found in only 10 percent of people.


 9) The coccyx


 Everyone knows that the coccyx is a part of the tail. In the evolution of demand in the wake of the person disappeared, but the need for the coccyx remains, because it works as a supporting some muscle structure, and helps the person to sit down and lean back.

 10) Appendix 



The human body does not need the appendix, so when there begins the inflammatory processes, it is removed. Most experts support Darwin's belief that the body has assisted in the processing of cellulose. However, over time the human diet has changed significantly, and therefore the need for appendix disappeared.
