The human body consists of only forty-three percent human cells. Such an incredible conclusion was made by researchers from the United States of America, who found that people are mainly composed of bacteria.
Microorganisms that live in the human body occupy a large part of it, because there are more cells of microorganisms in a quantitative ratio than cells, in fact, of a person. Although a serious philosophical question arises here, which sounds like: "What can generally be considered human cells?"
Fifty-seven percent of microbes is, by the way, not bad, because earlier scientists believed that the cells of microorganisms predominate with a ratio of ten to one.
Then the researchers decided that in the human body there are approximately the same human and microbial cells, and now, after a series of specialized experiments, it was decided that the ratio is fifty-seven to forty-three.
The microbes living in the human body have, as you might guess, their own genes, the totality of which is much more voluminous than human DNA. In general, now scientists are trying to understand what a person is. It turns out that we are a collection of organisms living in separate functional shells.
