Chimpanzees and humans are very close relatives by nature
To determine the age of a person, just look at his face. If the skin is covered with wrinkles, and her hair formed a graying — so the age of a person clearly more than 30 years. Scientists have long noticed that the hair on the body and the head monkeys chimpanzees also turning gray. They assumed that the hair of our immediate family also becomes bright because of age, but that there were no scientific confirmation. To completely understand this issue, it was decided to study photography to a variety of monkeys and find out at what age they begin to turn gray. As the duration of the life of a chimpanzee is about 40 years old, they were supposed to be gray somewhere in the 20-year-old. But as it turned out, the scientists are very wrong.
On the conducted research and its results was written on . A group of scientists from George Washington University (USA) studied more than hundreds of photos of the chimpanzees that live in different regions of Africa. They were interested in the amount of gray hair on the bodies of animals and the actual age of individuals — the good, the researchers had previously known of their date of birth. It turned out that the direct dependence between age of the monkey and the intensity of gray hair on their body does not exist.

Gray hair on the body of a chimpanzee can occur anytime. According to the researchers, the monkeys can be covered with white hair in the age of one year and 29 years and more. In most cases, gray hair was observed in individuals aged 30 to 35 years. While some of the older monkeys gray did not exist. It became clear that between the chimpanzee and the occurrence of light hair on their bodies there is no relationship. But what are the causes of graying hair?
Most Likely, the monkeys hair turns gray because of stressful experiences. For example, some individuals have been dealing with predatory animals or poachers — their bodies will clearly be more gray hair. But if the monkey lived a carefree life and most of the time just eating and care of their relatives, even in old age her hair will probably be shiny black. Just like people, you have probably noticed that some of your relatives and friends look much younger than their years? And all because they were able to remain calm in any situation and not worry over trifles.
Keep calm and be healthier
Stress can really cause discoloration of the hair. Recently, it was proved in a completely humane in my opinion the experiment. In the framework of scientific work, the scientists subjected the mice to stress — they worked hard causing severe pain in the body substances and simply shook their cage. Rodents who are not lucky enough to participate in this experiment, do covered with white wool. About this research and its results, I wrote extensively — if you're interested, be sure to read.

In Addition to the stress, the appearance of gray hair can contribute to the surrounding conditions. For example, if monkeys live in extremely hot regions of Africa, their body can become lighter so as not to draw warm sunbeams. Besides, gray hair can be hereditary factor — if the father or the mother monkey was gray, this can be transferred to him. In General, the causes of gray hair can be a lot, but age here is clearly not with it. At least in the example with the monkeys, it really is.

Clearly, Scientists will continue to study the gray hair in monkeys, because it is already clear in which direction to move. Take, for example, the assumption about the growth of gray hair in response to hot environmental conditions. Scientists can explore the photos of chimpanzees from different regions of our planet — if most individuals from hot spots with white hair, then the assumption is true. If you follow this logic, it turns out that "black" monkeys live in relatively cool areas.
In General, chimpanzees and humans have a lot in common — we and they are considered the closest relatives. But while scientists often hold them over cruel experiments, exposing them to radiation and even damaging organs. Even in the world there is a man who has dedicated his life to fighting for the rights of chimpanzees and other animals — read about it .
