  16. 16. Hierarchy Theory of evolutionEldredge 1986 “The clue to unravelling the evolutionary consequences of interactions [between ecosystems and species] derives from the observation that organisms seem to be both energy conversion machines and reproducing ‘packages’ of genetic information. As such they are integrated simultaneously into two largely separate, but interacting kinds of general systems” (1986, p. 351) 9

  20. 20. Hierarchy Theory of evolution It is what takes place inside matter-energy transfer systems that determines, in large measure, the patterns of stability and change in genetic systems that we call evolution.
