Lenton has taken an interest in the Gaia hypothesis for much of his career. Early in his career, in the journal Nature,[4] Lenton addressed a concern that the Gaia hypothesis was incompatible with the theory of natural selection by demonstrating that a model based on Daisyworld was strengthened by incorporating natural selection. Lenton, with Andy Watson, co-authored the book Revolutions that Made the Earth;[5] it expands on the ideas of James Lovelock on the Gaia hypothesis, by highlighting mechanisms by which the Earth system has been stabilised by negative feedbacks throughout Earth history.
