Introduction
There are several possible theories about the Origin of Life. This website aims to explore and explain some of these theories. Each page will introduce and new theory and describe the key points of it, explaining the likelihood of this being the environment in which the first life on Earth appeared. These theories are RNA world, hydrothermal vents, cold seeps and meteorites.
There is some debate as to what is considered the first life on Earth.
Some scientists state that to be considered alive, living things must have four characteristics; be able to eat, reproduce, respond to the environment and demonstrate an organised body structure. Therefore it is difficult to define whether it was the first RNA, amino acids, cells or multicellular organisms that classify as the first life.
The four main theories of the origins of life on Earths are the RNA world beginning with the primordial soup, hydrothermal vents, cold seeps and meteorite impacts. There is also the creationist theory that God created all life and some believe that all life was created as it is in the present and that no process of evolution has lead to the diversity of life on Earth.
