As author George R.R. Martin would attest, good writing takes time. For eons, DNA has been writing genetic scripts for “survival machines,” evolutionary biologist Richard Dawkins’s term for living organisms—their primary purpose being to live long enough to propagate their DNA. As author Samuel Butler recognized in 1877, “A hen is only an egg’s way of making another egg.”
But our planet has limited resources, so survival machines that had a leg up on the competition won the DNA replication relay. Selfish genes were locked in an arms race to craft survival machines that were better, stronger, faster. About 600 million years ago, an ancestral neuron emerged that heralded a new weapon: intelligence. It took nearly 4 billion years, but DNA has finally built a survival machine intelligent enough to expose DNA’s game. We are the first species to meet our maker.
The realization that we’re an apparatus for the ...
