More on semi-altruism: Darwin’s Unfinished Symphony argues that what sets humans apart is our ability to reliably teach (review here).
If we consistently teach well, it seems to me it must consistently yield rewards for the teachers. As with the argument for storytellers in the example above, this may be in the form of benefits from social connections. But, because we know time discounting is a thing and it takes time to teach people something, it seems likely to me that there is an intrinsinc reward for teaching. A reasonable way to describe teaching would be mutualizing information.
