NewsRecreation of ancient seawater reveals which nutrients shaped the evolution of early life
Scientists know very little about conditions in the ocean when life first evolved, but new research published in Nature Geoscience has revealed how geological processes controlled which nutrients were available to fuel their development. All life uses nutrients such as zinc and copper to form proteins. The ...
