In the re-imagined series, Cylons have reincarnation technology which allows them to be reborn after death. Could this be considered a form of Lamarckian evolution? I realize that they're technically not passing their adaptations to their 'children', but if we consider their reborn self as a 'child' it might work.
Evolution, whether Lamarckian or Darwinian, would require that its direction and course be determined by the blind forces of an external environment, without any purpose. Cylon evolution in that sense is not even evolution, because it is a conscious and purposeful process that is implemented according to a plan.
