Good Enough: The Tolerance for Mediocrity in Nature and Society

The book "Good Enough" challenges the dominance of Darwin's concept of natural selection and argues that the world is full of "good enough" organisms that persist despite not being the fittest. It suggests that traits that exceed the optimal configuration can be essential for survival and that optimization, competitiveness, and innovation are overrated in Western societies.

Why is the genome of a salamander forty times larger than that of a human? Why does the avocado tree produce a million flowers and only a hundred fruits? Why, in short, is there so much waste in nature? In this lively and wide-ranging meditation on the curious accidents and unexpected detours on the path of life, Daniel Milo argues that we ask these questions because weve embraced a faulty conception of how evolution—and human society—really works.
Good Enough offers a vigorous critique of the quasi-monopoly that Darwins concept of natural selection has on our idea of the natural world. Darwinism excels in accounting for the evolution of traits,but it does not explain their excess in size and number. Many traits far exceed the optimal configuration to do the job,and yet the maintenance of this extra baggage does not prevent species from thriving for millions of years. Milo aims to give the messy side of nature its due—to stand up for the wasteful and inefficient organisms that nevertheless survive and multiply.
But he does not stop at the border between evolutionary theory and its social consequences. He argues provocatively that the theory of evolution through natural selection has acquired the trappings of an ethical system. Optimization,competitiveness,and innovation have become the watchwords of Western societies,yet their role in human lives—as in the rest of nature—is dangerously overrated. Imperfection is not just good enough: it may at times be essential to survival.
