I think on a higher level the ability to fast might be the most important trait here (combined with the capability to innovate). At least Robinson Crusoe type economics has me belive that one of the important things for a civilization to advance is the ability to save and invest. So (simplified) the human can catch some fish, take some time of from the day to day grind of catching fish and try to build some device to catch even more fish (so basically investing the initial fish). With the ability to fast, this process can be sort of forced more (you can still gamble on building a better net even if you don't catch enough fish in the first place). Rinse and repeat in other areas and slowly "wealth" is built up. The longer you can go "save" without being forced to do something else, the more you can advance and that's exponential gains.

I'd be very curious if there's any studies on time sensibility accross species. Obviously it varies even among humans (cue children with candy experiment here). My hypothesis would be that the ability to delay satisfaction is quite vital for the development of a species. On a completely tangential note, I'd also be curious how it relates to "procrastination". Anecdotall, I fell like people who need everything "right now" struggle a lot less with procrastination.
