I have no philosophy to sell. No preconceived idea about how the
world works, or who we really are, or which is the one true religion.
All I do is look, listen and try to make sense of what I find,
in biological terms. Which means asking, again and again, the three
essential questions that put discoveries and insights into evolutionary
perspective: "Where did it come from?", "Does it have survival value?",
and "What happens next?".
