One Voice in the Cosmic Fugue
While reading Chapter 2, “One Voice in the Cosmic Fugue,” where he’s talking about evolution using his work with Nobel laureate H.J. Muller (discoverer of X-ray mutagenesis) and Drosophila melanogaster fruit flies as an example, a paragraph just jumps out at you:
The secrets of evolution are death and time — the deaths of enormous numbers of lifeforms that were imperfectly adapted to the environment; and time for a long succession of small mutations that were by accident adaptive, time for the slow accumulation of patterns of favorable mutations. Part of the resistance to Darwin and Wallace derives from our difficulty in imagining the passage of the millennia, much less the aeons. What does seventy million years mean to beings who live only one-millionth as long? We are like butterflies who flutter for a day and think it is forever.
What a magnificent turn of phrase. It sums up what we know of artificial and natural selection, underlines the breakthrough of its realisation, and wraps it into a beautiful philosophical illustration.
Knowing the TV series as I do, I’m looking forward to many more stand-out pieces such as this during my journey through the Cosmos, as it were. If you’re good, I may even share them with you…
