How did life originate? Most people believe that it began with a process called abiogenesis, the development of living organisms from nonliving mater. According to this belief a very simple life form came into existence and over millions of year its descendants changed through the process of evolution to produce the large variety of life that exists today.
Not everyone believes in abiogenesis and evolution. Some people believe the Bible’s account of how life originated; it was created by God only a few thousand years ago.
Believers in abiogenesis and creation both agree that new varieties of life are constantly being produced by a process called natural selection. An examination of how this process works might show whether abiogenesis or creation is the most likely starting point for it.
