The animal world is beautiful and diverse, and the deeper a person looks into the processes taking place in it, the more amazing views open to him. Thanks to new technologies, not only scientists, but also ordinary people can look at these beauties. Such an opportunity, for example, was recently provided by the Dutch director Jan van Eycken, who made a short film about the transformation of a tiny cell into a living salamander.
The film is called "Becoming" and only lasts about six minutes. During this time, the director shows the whole process of development of the salamander from the moment of fertilization to the state when it finds the strength to escape from the field of view of the camera. It would be impossible to see all the beauty of the development of a living organism in real time, since this process lasts about three weeks. The author has simply compressed this time to six minutes.
In the video, you can contemplate all the processes that occur with living organisms in the embryonic period. After the formation of the embryo, the process of its cleavage begins, in which its volume does not change, but it divides into smaller cells. The next stage of development is gastrulation, during which the moving cells form germ layers. From them, in the course of organogenesis, body tissues are formed: nerves, skin, mucous membranes and muscles.
Recall that with the help of embryos, scientists are able to save rare animals from complete extinction. For example, at the end of 2018, an international team of scientists decided to revive the population of endangered northern white rhinos. They created hybrid embryos and raised them to the point where they could be transplanted into live females.
