In popular discourse, the theory of evolution has become a victim of its own success, reduced to sound-bites such as “survival of the fittest”. Biologists will of course quickly point out that this is an oversimplification, though philosopher Daniel S. Milo takes things a few steps further. Good Enough is a thought-provoking critique of the dominance of adaptationist explanations. He argues that, while natural selection is important, it is not the only, possibly not even the default mechanism, in evolution. No, Milo claims, the mediocre also survive and thrive.
From the perspective of biology, the rules for the game of life are simple: acquire energy, avoid becoming food for someone else in the process, and pass on your genetic information. This simple theme has given rise to an incredibly rich and diverse panoply of approaches and solutions. Strange Survivors, written by Puerto Rican biologist Oné R. Pagán, is a love letter to the many wonders that biology has to offer. I am sure he would approve if I said: “Prepare to be amazed!”
