Evolution did not stop about 4 million years, people continue to evolve. So far, the changes seem invisible, but after a few million years of the Earth future residents will see much more differences between those people who lived in the twenty-first century, and those who live a few million. In the future, at least the eye is always interesting to look at. Here's how distant future might look like Homo sapiens .
12 hypotheses about how people change over a few million years ago:
Height. Over the past 200 years, the population of the developed world people's height increased by about 10 cm due to improved living conditions and food quality. If you continue to be such a condition, the average height of a man will be about 2 meters, but no more. Women - about 180 cm.
Skin. The skin will become darker as the race continues, the more mixed. Dark skin also becomes more resistant to harmful UV rays, which in the future through the Earth's atmosphere to penetrate very much.
Body. Decline of human effort, because most of the work was done by machines and robots. Physical strength will not be seen, so the muscles will decrease. Technology is an integral part of the body: the human body to be implanted in a variety of microprocessors and other high-tech devices.
Hands. The regular keyboard and a touch-screen use of human hands and fingers become thinner and longer.
Legs. The human body will eventually adapt to a sedentary way of life: long, strong and muscular legs will become obsolete. Fibula fall, what are the usual terrestrial animals. The main function of bone - turn leg - was a very important human ancestors who climb trees. However, modern people's ability to move the ankle to the sides became more harmful than useful, because the risk of dislocation risk.
Toes. Our ancestors toes were required for climbing trees. From the Australopithecus genus of human toes greatly reduced, and it is believed that this is not the end. There may be a reduction in the number of fingers and toes. Terrestrial animals the toes of the course of evolution dropped one of these examples: horses and horses.
Chest. As long run more difficulty in accessing the oxygen from the atmosphere, the lungs increases, and the chest.
Head. So far it is not clear whether the man after a few million years will be higher or lower than the skull now. On the one hand, compared with the first Homo sapiens sapiens skulls, future human brain will become smaller. On the other hand, due to a higher incidence of Caesarean sections more children with big heads will be able to survive. In the long run this on the average head size. For this reason, natural childbirth will disappear in the future.
Teeth. People will adapt to eat softer foods. Dental quantity and size of the decrease, resulting in the decreased jaw and mouth.
Digestion. Due to the abundance of easily digestible food, and easy availability of human intestine shorter. DELTA shorter and lumbar spine.
Eyes. If the mouth is lower, the eyes become larger and this offsets the lack of facial expressions.
Body hair. Body hair need has long been extinct, so it is natural that after a few million years of the human body wont have hair. What will happen with the hair on the head, it is difficult to predict.
