“Scientists are slowly waking up to an inconvenient truth – the universe looks suspiciously like a fix. The issue concerns the very laws of nature themselves. For 40 years, physicists and cosmologists have been quietly collecting examples of all too convenient “coincidences” and special features in the underlying laws of the universe that seem to be necessary in order for life, and hence conscious beings, to exist.”
—Paul Davies
The illustration above shows one of these anthropic coincidences.  There are many others in cosmology, laws of physics, chemistry and molecular biology.   These are discussed in ESSAY 4: Are We Special, The Anthropic Coincidences.
