Is there an evolutionary advantage in being religious? | Skeptic Society Magazine
For a biologist like me, the interesting questions about religion have always been where did it come from and why did it evolve? I taught evolutionary biology in a Catholic University in the most Catholic country in the world – Brazil. Some of my colleagues here in the UK thought that must have been very challenging, but it wasn’t. The Brazilian population is unusual in that 60% of the population are religious and also believe in evolution by natural selection.
