Evolution

Organic chemistry is just carbon chemistry, no more mysterious than any other chemistry, just immensely richer because of the unique associative properties of the carbon atom. Organic carbon compounds are everywhere. They make up 20 percent of interstellar dust, and interstellar dust makes up 0.1 percent of galactic matter. In this organic cloud, which pervades the universe, life is almost bound to arise, in a molecular form not very different from its form on Earth, wherever physical conditions are similar to those that prevailed on our planet some four billion years ago. This conclusion seems to me inescapable.
