Thomas Brasier Cavalier-Smith, Philosophical Transactions of the Royal Society B: Biological Sciences


This is a review article published in Philosophical Transactions of the Royal Society B. It summarizes the current consensus and points of debate regarding the age and history of life on Earth. It covers biogeochemical, fossil, and phylogenetic data bearing on two primary questions - the earliest life on Earth, and the process of atmospheric oxygenation. This article is very technical, but would make good background reading for teachers from the secondary level upward. The bibliography is also an excellent resource for reading materials on early microbial evolution.
