Origin and evolution of life has been of particular interest to mankind. Life on Earth is a cellular system that is self-sustained based on the genetic information it contains and capable of undergoing Darwinian evolution. The genetic information is stored and maintained in the genomes, but it remains a mystery how the genome evolution is related to the organismal evolution and to the environmental changes. In this session, we discuss the interrelationships among the ancient genome sequence (reconstructed from comparative genomics of living organisms and direct characterization of ancient DNA), the phenotypes inferred based on the encoded biological functions (metabolic pathways, metallo-proteins, developmental programs, etc.), and the environments in which those ancestral organisms inhabited, from a wide variety of viewpoints, including geohistory and biohistory studies, geometallomics, microbial ecology, organic geochemistry, developmental genetics, and genome sciences.
