Which of the following evolved first on the primitive earth?
- Viroids
- Coacervates
- Cyanobacteria
- Mycoplasma
The correct answer is: Coacervates
Origin of Coacervates The large organic molecules, which were synthesized abiotically on the primitive earth later come together, and due to intermolecular attraction, they formed large colloidal aggregates. Such water bound aggregrates have been named microspheres by Sydney Fox. Later these colloidal bodies were named coacervates by Oparin
