TK, I have also been thinking of brood parasitism or social parasitism and how it applies to our current situation. Its interesting that a lot of brood parasites are from the same or closely related species especially in bees and wasps. There is an interesting behavior called “mafia hypothesis” which has been observed in cuckoos. They attack the nest of the host bird if it rejects the parasite egg. Destroy the nest! This shit is not learned, it is genetic.
