In the News (Chen-Yu Zhang’s group at Nanjing university, China, from gazeta.ru): “Scientists have discovered that plants and mammals exchange their genetic codes. With food, we consume not only nutrients but also information…
“The detection of plant miRNAs in human tissues surprised biologists. After all, alien plant genes taken with food must be broken down during digestion, metabolism, and molecular decomposition in our internal tissues and fluids, which are under control of the human DNA.
“As it turned out, ‘plant’ genes can reprogram certain human genes, change their function, and thus regulate the physiology of the person who consumed them.
“The formula ‘you are what you eat’ makes sense not only in metabolism, but also in the exchange of genetic codes. Food, it turns out, is the chain of communication between all parts of nature.”
My Comment: There is nothing astonishing in such discoveries. We initially consider nature as a single whole divided into parts and levels only in our imagination.
Likewise, there are no physics, chemistry, biology, mineralogy, and so on in nature, but only one nature, and only our limited abilities to study it in its entirety, as it is, as a single whole, compels us to divide it into parts we can analyze.
But gradually, we come to realize its full picture, and that is one of the examples: Everything is interconnected at the level of transmitting genetic information between the levels of nature (as we conventionally divide it).
