Natural selection for supernaturalism. One altered state of consciousness that seems to exist universally across time and cultures is religious experience - experiences that are perceived to have a supernatural origin or explanation. It seems that we are hard-wired to be religious (or superstitious). From the perspective of evolutionary psychology, what adaptive function might it serve for us to have evolved this tendency?
Note that the truth or falsity of any particular religious beliefs are not at issue here (and are not relevant to the question). The question is, why, from an evolutionary perspective, did we evolve the tendency to believe in the supernatural? The fact that we evolved to believe it does not make it true (we also evolved to experience all sorts of perceptual illusions), nor does being able to explain in evolutionary terms why we believe it make the belief false. So please refrain from expressing any opinions about the truth or falsity of religious beliefs, and focus instead on how the tendency to have such beliefs might have increased our ancestors' reproductive fitness - how it could have made them more likely to leave lots of descendants (who would also have that trait)

For example, the belief in a benevolent God can provide comfort and hope in times of difficulty. The belief in an afterlife can provide a sense of meaning and purpose to life, even in the face of death.
Promoting social cohesion and cooperation
Religious beliefs can also promote social cohesion and cooperation. Shared religious beliefs can provide a sense of community and belonging, and they can also motivate people to work together for common goals.
For example, many religions teach the importance of helping others and caring for the community. These beliefs can motivate people to volunteer their time and donate to charitable causes. Religious beliefs can also promote peace and understanding between different groups of people.
Coping with anxiety and uncertainty
Religious beliefs can also help people to cope with anxiety and uncertainty. The belief in a higher power can provide a sense of security and comfort in times of stress. Religious rituals and practices can also help to reduce anxiety and stress.
For example, prayer can be a way to express worries and concerns to a higher power. Meditation can be a way to calm the mind and focus on the present moment. Religious rituals such as going to church or celebrating holidays can provide a sense of community and belonging.
Natural selection for supernaturalism
It is possible that religious belief evolved due to natural selection. Religious beliefs can provide a number of benefits, including explanations for the natural world, social cohesion and cooperation, and coping with anxiety and uncertainty. These benefits may have given people with religious beliefs a selective advantage over those without religious beliefs.
For example, people with religious beliefs may have been more likely to survive and reproduce in times of hardship. They may also have been more likely to form strong social networks and cooperate with others.
Conclusion
The adaptive function of religious belief is a complex and controversial topic. There is evidence to suggest that religious belief can provide a number of benefits, including explanations for the natural world, social cohesion and cooperation, and coping with anxiety and uncertainty. It is possible that these benefits gave people with religious beliefs a selective advantage over those without religious beliefs.
However, it is also important to note that religious belief is not without its drawbacks. Religious beliefs can be used to justify violence and oppression. Religious beliefs can also lead to conflict and division between different groups of people.
Overall, the adaptive function of religious belief is a complex and nuanced issue. There is evidence to suggest that religious belief can provide a number of benefits, but it is also important to be aware of the potential drawbacks of religious belief.
Sample Answer
From the perspective of evolutionary psychology, the adaptive function of religious belief may be to provide explanations for natural phenomena that are otherwise difficult to understand, to promote social cohesion and cooperation, and to cope with anxiety and uncertainty.
Explaining the natural world
Religious beliefs can provide explanations for natural phenomena that are otherwise difficult to understand, such as the origin of life, the existence of suffering, and the inevitability of death. These explanations can help to reduce anxiety and uncertainty, and they can also provide a sense of meaning and purpose in life.
