Can Intelligence be used more than once in a turn or round, to feed the same species repeatedly?
The designer said Intelligence is independent of feeding and can be used as often as cards allow, and noted the once-per-turn wording was from the first print.
Yes. Intelligence can be used as many times as you have cards to discard, on different feeding actions across the turn and the round. Each use that feeds a species also triggers Cooperation again. The once-per-turn limit comes from the first print run and was reworded in later printings.
