May I make a suggestion? We might all try to have a look at what the modern consensus among evolutionary biologists actually is, with regard to group selection.

By all means let's do so. The modern consensus among evolutionary biologists is that organisms work to maximise their inclusive fitness, as explained by the late W D Hamilton. If you actually read the modern literature on evolutionary biology, you will find that Hamilton's theoretical framework is overwhelmingly what guides field workers in ecology, ethology, behavioural ecology, sociobiology, evolutionary psychology . . . I can't see what else 'consensus' might mean. One thing is for sure, D S Wilson, to whom Helga Vierich bizarrely refers us, does not represent a consensus of anybody but himself.
