mmmm it's equally likely that mitochondria's precursors were self interested parasites or predators, whose negative effects were competitively neutralized by defensive host adaptations that exploititively colonialized them. No intelligence or cooperation is required for co-opt-ation to evolve. It's a straightforward consequence of game theory.

That is in no way at odds with what I said.
