Caledonian, Those conditions weren't created in the laboratory, because the individual strategy dominated over the group; ergo, the conditions necessary for that to happen were not met.

I am not sure how to interpret this. When we remove whole groups from the gene pool because of some group characteristic (i.e. averaged over the population of that group), it sounds for me natural to call that a group selection. Do you have some different meaningful definition of group selection? What does it mean in general when you say that the individual strategy dominates?
