How Life Began: Evolution's Three Geneses

Alexandre Meinesz

Abstract

The origin of life is a hotly debated topic. The Christian Bible states that God created the heavens and the Earth, all in about seven days roughly six thousand years ago.

Keywords: origin of life, natural selection, bacteria, unicellular organisms, evolution, nucleated cells, multicellular organisms, biodiversity, mutation, recombination
