And when we take that, we take this idea of what culture is doing and add it to what the long-term trajectory -- again, in life's evolution -- we find that each case -- each of the major transitions in life -- what they're really about is accelerating and changing the way in which evolution happens.
I kad uzmemo to, uzmemo ovu ideju toga što kultura čini i dodamo ju dugoročnoj putanji -- ponovo, u evoluciji života -- nalazimo da svaki slučaj -- svaka od glavnih izmjena života -- ono oko čega se sve vrti je ubrzavanje i mijenjanje načina na koji se evolucija događa.
