Whenever a belief or an attitude is shared by all (or most) of humanity, it must have offered us a significant survival advantage in our evolutionary past. After all, people without this belief/attitude were wiped off from the gene pool!
In an earlier post, I discussed about how our sense of spirituality is suspected to be an evolutionary by-product. Scientists working on evolution suspect that our compulsion to subscribe to concepts like God and Life-Purpose might have similar evolutionary origins.
Take, for example, an animal which sees a movement in the bush. The animal must quickly decide if it is a fake alarm (say, rustling of the wind) or a predator. An animal which mistakes a predator for rustling of the wind will get eaten up. Whereas, an animal which wrongly concludes the rustling of the wind to be a predator lives to see another day. Over a period of time, the “better safe than sorry” animals, the ones who see an agent in the rustling of the wind, dominates the gene pool.
This compulsion to err on the safe side has endowed all of us with a bias. Because of this bias, we (and all other animals) often see an agent/pattern in most random noises. Social biology thinks that we may have invented God and Life-Purpose because we have this compulsion to imagine an invisible hand in everything.
Of course, this doesn’t disprove the existence of God. But it certainly puts a strong argument that our internal compass might be always stuck towards the North.
