Universal Ancestor * DNA as Genetic Storage * Ester Bonds in Cell Membranes

The text explores the evolutionary lineage and key characteristics of various life forms, starting from the universal ancestor. It highlights the role of DNA as genetic storage and contrasts the structural differences in cell membranes, such as ester bonds in bacteria and ether bonds in archaea.
