He developed his arguments in a geological context based, in part, on the fossil faunas of the Burgess Shale (which are described in section 11.3). Although most palaeontologists now think he pushed these ideas too far, they are still good illustrations of the potential for historical contingency to have a major role in the history of a planetary ecosystem.
