What I Learned About Investing from Darwin

Convergence is ubiquitous and not limited just to the external appearance or morphology of animals. It is also widely observed and documented in animal behavior and in plants, fungi, and even bacteria. Let’s start with behavior. What do you think these four species—a cobra, a stickleback fish, an octopus, and a spider—share? There is no convergence in body form here, unlike the Caribbean anoles. But a behavior has converged among them that has led to the success of each of their species: the females of the species guard their eggs. One of the best examples of convergent behavior is observed in humans and—hold your breath—ants! And I have witnessed this convergence with my own eyes. When I was on a family vacation in the stunningly beautiful Peruvian Amazon, I stumbled upon the tiny creatures that had beaten our human ancestors to the discovery of agriculture by many millions of years: the leafcutter ants. I had waited years to witness the miracle, and there it was in its full linear glory. A long single column of thousands of large green leaves appeared to be miraculously moving in perfect synchrony of their own volition on the forest floor. Each large leaf was being carried by a single tiny ant, who purposefully disappeared underground to pass on the booty to her specialist sisters. These ants chew the leaves to grow a fungus garden used for food for the entire colony. Not unlike human farmers, these ants produce fertilizers (amino acids and enzymes) to aid the fungal gro...
