 Life, according to Denton, did not exist until the initial conditions of the universe were fine-tuned (see Fine-tuned universe).Denton was influenced by Lawrence Joseph Henderson (1878-1942), Paul Davies and John D. Barrow who argued for an anthropic principle in the cosmos (Denton 1998, v, Denton 2005).His second book "Nature's Destiny" (1998) is his biological contribution to the anthropic principle debate, dominated by physicists.
