A multitude of religions from all over the planet agree on the same story of the creation of the human being, in which an all-powerful god creates women and men from nothing with a brain already well furnished. The reality is much less lyrical, as suggested by placozoans, animal creatures smaller than a millimeter that float in seawater like grains of sand. They go unnoticed, but they are extraordinary. Under the microscope, they are like tiny pancakes, without any organs, much less a brain. However, these strange animals are capable of coordinating to attack in group to their prey. The Spanish biologist's team Arnau Sebé Pedros reveals this Tuesday that in the cells of these unusual beings the origin of the neurons, responsible for human thought, can already be sensed.
