This happens once in ages! Two life forms combined into one

An international team of scientists includes experts from the Massachusetts Institute of Technology (MIT), the University of Rhode Island, the University of California at San Francisco, the University of California at Santa Cruz, Lawrence Berkeley National Laboratory, the Instituto de Ciencia de Barcelona, ​​the National Taiwan Oceanic University, and the University of Kochi in Japan, I observed an incredible evolutionary event.

If the researchers are right and Between a type of algae commonly found in the oceans and bacteria, as a result of which these two life forms merged into one, the initial endosymbiosis actually occurredThis is only the third time in Earth's history. Firstly, through the evolution of mitochondria, it gave rise to all complex life as we know it, and secondly, plants appeared on our planet.

This process involves algae ingesting bacteria and providing them with nutrients, energy, and protection in exchange for functions they were unable to perform before — in this case, the ability to fix nitrogen from the air. then Algae house bacteria as an internal organ called an organelle, which becomes essential for the functioning of the host.
