1.Characteristics of Early Earth: Earth formed about 4.6 billion
years ago Produced very simple cells through a sequence of
stages
1.abiotic synthesis, small organic molecules
2.joining of these small molecules into macromolecules
3.packaging of molecules into protocells
4.origin of self-replicating molecules
