Ahh, I see.

in the first context it was 'group selection' that the researches intended to facilitate but not what actually occurred. The resulting outcome was instead individual selection being the dominant factor in how the groups evolved. This is to say that 'group' and 'evolution' are used correctly as independent terms, not as a phrase referring to a single construct.

The latter two should be 'group selection' so I corrected my follow up there, and the Matt quote with suitable edit-brackets to maintain the consistency in reply.
