The Path of Evolution.

An international team of researchers, mostly from Germany, although with members from the USA, Italy and France have created, developed, cultivated, I don't know what term to use, let's say they have achieved with the help of stem cells, which are those that they can divide into generating any other type of specialized cell, because with these stem cells what they have made is a mini brain.

A small mass that mimics brain functions but at a very basic level, however, the mass continued to develop and after a month it created its own optical structures capable of reacting to light, is what you see above.

Scientists believe that it is the most similar to what happened with the origin of the first animals, within these primitive eyes networks of electrically active neurons that reacted to light were formed, a lens was also developed and corneal cells are like in an eye real and this not only happened once, researchers have created 314 mini brains and in 73% of them they developed optical structures like the ones you have seen in the image.

Researchers are now looking for a way to keep these organs alive for longer to carry out longer-term research, but why grow mini brains in a laboratory? It is a common practice that is done with other organs to allow The researchers experiment with different techniques or with drugs that are later applied in humans. In the present investigation, what was wanted was to better understand how the eyes are formed and how to prevent diseases from the beginning of their growth.
