Salván. The active role of cyanide in the geochemistry of phosphorus more than 4 billion years ago completes a model in which urea is the key component in the generation of the first phosphorylating agents (which transfer phosphate to organic molecules), which made possible the evolution towards life. The slurry inspiration – struvita This research emerged with a curious connection: the formation of large crystals in the slurry pit of a pig farm in Gerona. His owner, surprised by his training, contacted Menor-Salván and sent him samples for study. He found that it was the mineral struvite (magnesium ammonium phosphate). Its formation in a medium rich in urea, an essential precursor to the origin of life, inspired the solution to the

“phosphate problem”: struvite (and a Germany Phone Number List related mineral, newberyite) is a good phosphorylating agent and could have been formed as mineral before the origin of life, something that many scientists thought was not possible. The combination of urea and cyanide with the formation of new minerals inspired research on early phosphorylation in CCE. The scientific results within which this study is framed are part of NASA’s Astrobiology program and are “a critical part of the agency’s work to understand the Universe, advance human exploration, and inspire the next generation.” A new study, published in Science Advances , proposes that the BAZ1B gene regulates the appearance of the modern human face by affecting the cells of the neural crest, which are
involved in tissue development. Therefore, it could have influenced the facial changes that have occurred throughout human evolution. These results support for the first time in an experimental way the theory of human self-domestication, a hypothesis which explained that the first humans selected couples who were willing to behave for the benefit of society, giving rise to modern humans less aggressive than human beings. of their ancestors, with slender facial features and better suited to non-verbal communication. The idea of self-domestication dates back to the 19th century. It is believed that the anatomical and cognitive behavioral traits of modern humans, such as docility or a graceful physiognomy, may come from an evolutionary
