Mutations are essentially random, while selection pressures work to prefer certain outcomes over others. There is tremendous divergence of species over time, but also repeated convergence to forms and mechanisms that are unmistakably useful. We see this clearly in eyes and fins, but the basic pattern also holds for brains and forms of social organization. I talk with philosopher Rachell Powell about what these ideas mean for humans, other terrestrial species, and also for forms of life we have not yet encountered.
