Physical and Brain of Modern Human is Shinking

Scientists from the University of Cambridge said the man had passed their peak periods and modern humans are smaller and shorter than their ancestors.

And if that is not pathetic enough, our brains was also smaller. The findings reverse the assumption that human beings have grown taller and bigger.

The decrease was, say scientists, have occurred during the last 10 thousand years. They blame the farm with a limited diet and urbanization at the expense of health and lead to the spread of disease.

This theory comes from studies of human fossils found in Africa, Europe, and Asia.

The earliest human fossil from Ethiopia, 200 thousand years ago, bigger and stronger than modern humans. This was disclosed by Dr. Marta Lahr, an expert on human evolution.

Fossils found in the caves of Israel and come from 120 thousand to 100 thousand years ago it was revealed that people high and muscular, a pattern that persisted until relatively recent times.

Human beings 10 thousand years ago has a weight of 12st 8lb (79.8 kg) and 13st 6lb (85.7 kg). Currently, the average is between 11st (69.9 kg) and 12st 8lb (79.8 kg).

Dr. Lahr, who last week presented its findings to the Royal Society, Britain's most prestigious scientific institute, described the changes as something that is 'appalling'.

"We can see that humans evolved continuously, but in this body size did not happen until 10 thousand years ago in which they have been changed substantially so that the question is why this should happen," he said.

Points when the transition from hunter-gatherer lifestyle to agriculture began 9,000 years ago. Meanwhile, agricultural produce abundant food, focus on a small number of foods that cause deficiencies of vitamins and minerals that inhibit growth.

In China, farmers are beginning to rely on cereals such as wheat, rice, and corn, all of which lack of niacin, vitamin B is essential for growth.

However, the emergence of agriculture do not explain why the brain is also shrinking.

Male brains 20 thousand years ago measuring 1500 cubic centimeters. The brain of modern man's average of only 1350 cubic centimeter - a decrease equivalent to the size of tennis balls. Female brain has shrunk with the same proportion.

That does not mean we are less intelligent and otherwise we have learned to make the best use of our resources.

Dr. Lahr said, "During the time evolution is a big energy savings that make the brain is smaller, but more efficient as we see now with the computer processor."
