The Universe Structure, Function, Origin of Life up to Homo sapiens - Jose O'Daly - Bog

Eight planets: Mercury, Venus, Earth, Mars, Jupiter, Uranus, Neptune and Pluton are part of the Solar System of a galaxy, the Milky Way with 200 billion stars. The Galactic Center has a massive black hole. The Universe is expanding after the Big Bang. Lightning provided the energy for life to begin, generating amino acids and sugars from an atmosphere. The DNA store information for other molecules. Life on Earth began > 3 billion years ago. RNA, created DNA and proteins. Panspermia: Life came to earth from space. Abiogenesis is a process by which life has arisen from 4 key chemicals: lipids for cell membranes, carbohydrates for sugars, amino acids for protein metabolism, and nucleic acids DNA and RNA for heredity. Polycyclic aromatic hydrocarbons (PAH) are precursors to the RNA world. A protocell is a self-organized, spherical collection of lipids a stepping-stone to the origin of life which requires a loss of entropy, when molecules organize into living matter. Chemiosmosis is a cell's primary system of energy conversion. Mitochondria produce adenosine triphosphate the energy currency of the cell. Theories of Origin of Life: 1. Living organisms were formed on our planet by God..
