I wandered into the New Scientist website earlier, as you do, and came across an interesting piece on primate behaviour. In fact, I’ll post a link to it here.
The interesting bit is the third section “No Reward”, it seems that the chimps will help out without expectation of reward. From the article: “Such altruistic helping behaviour is common in humans, but had never been documented in other animals before.”
It seems to me that there are people who like to make out that followers of their given religion are the only source of good. I wonder what they’d make of this? I personally find it reassuring tht altruism seems to be built in to animals to some degree, that it’s not just a thing contrived by humans.
