"IF asked to identify the intellectual founder of their discipline, most economists today would probably cite Adam Smith.
But that will change. Economists’ forecasts generally aren’t worth much, but I’ll offer one that even my youngest colleagues
won’t survive to refute: If we posed the same question 100 years from now, most economists would instead cite Charles Darwin. ..
The central theme of Darwin’s narrative was that competition favors traits and behavior according to how
they affect the success of individuals, not species or other groups.
As in Smith’s account, traits that enhance individual fitness sometimes promote group interests.
For example, a mutation for keener eyesight in hawks benefits not only any individual hawk that bears it,
but also makes hawks more likely to prosper as a species.
In other cases, however, traits that help individuals are harmful to larger groups",
