Formation of Planet Earth: S. Eva Nessenius found new answers to the big questions about the origin of planets and life. Her unique findings show the ancestry of today´s living beings from the Precambrian biosphere and a biogenously formed Pangea. A new understanding of earth-formation on the basis of hydrous accretion, very early chemical evolution and biomineralisation as fundamental processes is the key to understand the early formation of planets from slowly rotating gas-giants. It is recommended to read the free PDF: Planet Formation and Evolution - The Biogenic Origin of the Early Continents. You find it with Google.
