People should only be as big as ... chickens in the future

In most of human history, large body sizes always have many advantages. Can be seen from our ancestors, they grow taller, faster, healthier to support the hunting and defense process.

In the future - People should only be as big as a chicken

But according to research by Arne Hendriks - a Dutch artist who is knowledgeable and passionate about science - in today's world, rising is not much meaningful in survival.

Humans should only be about 50cm high.

And according to what he learns, the size of the human body today should only be about . 50cm (equal to the height of a chicken). Hendriks said that, with such size, people only need 2% - 5% of resources and food for an adult today.

Specifically, he explored historical documents and said, reality - the human body once had a shrinking period. Our ancestors of the past - Hominid people - have a very fast growth height. About 500,000 years ago, the human species moved from climbing species to the ground, so the body had to be bigger and stronger.

But Professor Christopher Ruff of Johns Hopkins University, by the time of 50,000 years ago, human body size had shrunk. It is thanks to the appearance of powerful weapons and high damage, like spears and marks . making fighting more effective.

However, in the technological age, nutrition is growing, people are again . big. According to statistics from 1900, the average adult male is 1.67m, the average height is now 1.77m. This figure for women is 1.6 - 1.62m.

For many people, such a growing body size is considered a good signal. But according to Hendriks, we need to remember that the world population is still growing strongly, along with the decline in resources. Therefore, the large size in this case is not beneficial. In addition , tall people often have a lower life expectancy because the skeleton is under pressure.

A chicken can eat enough for a hundred people.

Hendriks said: "When the body gets smaller, we will consume less resources. At this time, a tomato is enough to have a good soup and a chicken is enough to feed hundreds of people."

To shrink the body, Hendriks believes that in the future, scientists can think of a drug that suppresses growth in size , or uses genetic modification.

People today are even able to "rewrite" genes, so this is possible.

Some people have concerns that when the brain shrinks, the brain is also small, and we can get smart. But according to Hendriks, brain reduction does not mean we will be less intelligent. Evidence is that in the last 20,000 years, human brain has shrunk, but we are much smarter than our ancestors.

Although the idea of ​​Hendriks is somewhat . unrealistic, but receives a lot of approval from many people. Many people even think that this is the only way to rescue this planet.
