How Religion--And Darwinism--Evolved

According to the headline: Religion is a product of evolution, software suggests. Of course, the fact the software was written by an evolutionary anthropologist may have helped:

By distilling religious belief into a genetic predisposition to pass along unverifiable information, the program predicts that religion will flourish. However, religion only takes hold if non-believers help believers out – perhaps because they are impressed by their devotion.

"If a person is willing to sacrifice for an abstract god then people feel like they are willing to sacrifice for the community," says James Dow, an evolutionary anthropologist at Oakland University in Rochester, Michigan, US, who wrote the program – called Evogod (download the code here).

Dow is by no means the first scientist to take a stab at explaining how religion emerged. Theories on the evolution of religion tend toward two camps. One argues that religion is a mental artefact, co-opted from brain functions that evolved for other tasks.

Another contends that religion benefited our ancestors. Rather than being a by-product of other brain functions, it is an adaptation in its own right. In this explanation, natural selection slowly purged human populations of the non-religious.

...To simplify matters, Dow picked a defining trait of religion: the desire to proclaim religious information to others, such as a belief in the afterlife. He assumed that this trait was genetic.

The model assumes, in other words, that a small number of people have a genetic predisposition to communicate unverifiable information to others. They passed on that trait to their children, but they also interacted with people who didn't spread unreal information. [emphasis added]

Ah, and so evolved the Darwinists--and stockbrokers.
