Answer 1

Four major stages that are thought to be required for the origin of life are :

1.The abiotic (nonliving) synthesis of small organic molecules, such as amino acids and nucleotides.
2. The joining of these small molecules into macromolecules, including proteins and nucleic acids.
3. The packaging of these molecules into "protobionts", droplets with membranes that maintained an internal chemistry different from that of their surroundings.
4. The origin of self-replicating molecules that eventually made inheritance possible.
