Origin of Life on Earth
Life is: “A self-sustained chemical system capable of undergoing Darwinian evolution”
– Gerald Joyce, NASA scientist, 1994
There are three possibilities with regards to the origin of life:
1.
Life arose from non-life through natural processes on Earth
2.
Life arose elsewhere in the Universe and was transported to earth
3.
Life arose on Earth through supernatural intervention
This article explores the possibility and evidence for the tantalizing idea that life arose and evolved from nonlife and through natural processes.
