At least one scientist seems to think religion gives people an advantage when it comes to long term survival.. But I am not so sure they should be happy about the traits he lists:
Rowthorn contended that scientists widely agree that religion has biological foundations. Belief in the supernatural, obedience to authority, and affinity for ceremony and ritual depend on genetically based features of the human brain, he wrote, citing several influential studies.
He also goes on to talk about how shared myths can bring people together. I am pretty sure nothing he mentions is really a good thing.
