British scientists from Northumbrian University and their international colleagues have studied ancient stromatolites in Zimbabwe to understand how the nitrogen cycle can affect the development of life in the oceans first. Tien. The study was published in the Journal of Natural Communication Science (NATCOMS).

The bald sheet is fossil structures formed by ancient microorganisms. Their age exceeded 2.75 billion years old. Experts find abnormal nitrogen prints that show the accumulation of ammonium (biological nitrogen form) at the depth of ancient oceans. Ammonium can increase to surface due to rising – the process of deep water lifts to the surface.

Scientists believe that volcanic activity and heat springs play a major role in providing nitrogen in the first form of life. Nitrogen, accumulated in the form of ammonium, can become an important resource for microorganisms, contribute to their development and prepare the platform for the appearance of oxygen in the atmosphere. “The volcano was extremely positive 2.75 billion years ago and had a long -term impact on the evolution of life,” the authors of Discovery noted.
