I do think that acting towards group goals is important for humans, but, I don't buy that it is exclusive to humans. One example that comes to mind is the bubble net feeding practice of humpback whales. In this process there is division of labor: some blow bubbles, some herd the deep fish. Then, after the fish are corralled, the whales take turns eating the fish. I had a hard time understanding what the author meant by (what I understood as) 'group goals' versus 'group goals where the group acts as a unit'. They seem the same to me, and the bubble net fishing practice seems to show that cooperation extends beyond humans.
