Drawing on Darwin's theory of natural selection, he laid the foundations for a response to urban growth that drew loosely on ideas of evolution, but which ultimately became established through the imposition of a top-down 'Organic' order in city and regional plans associated with the work of Patrick Abercrombie, one of Geddes' best-known followers.
