Do not fill this in! === Pre-Darwinian === The [[Scientific revolution|"New Science"]] of the 17th century rejected the Aristotelian approach. It sought to explain natural phenomena in terms of [[physical law]]s that were the same for all visible things and that did not require the existence of any fixed natural categories or divine cosmic order. However, this new approach was slow to take root in the biological sciences: the last bastion of the concept of fixed natural types. [[John Ray]] applied one of the previously more general terms for fixed natural types, "species", to plant and animal types, but he strictly identified each type of living thing as a species and proposed that each species could be defined by the features that perpetuated themselves generation after generation.<ref>{{harvnb|Mayr|1982|pp=256–257}} * {{harvnb|Ray|1686}}</ref> The [[biological classification]] introduced by [[Carl Linnaeus]] in 1735 explicitly recognised the hierarchical nature of species relationships, but still viewed species as fixed according to a divine plan.<ref>{{cite web |url=http://www.ucmp.berkeley.edu/history/linnaeus.html |title=Carl Linnaeus (1707–1778) |last=Waggoner |first=Ben |date=7 July 2000 |website=Evolution |publisher=[[University of California Museum of Paleontology]] |location=Berkeley, California |type=Online exhibit |access-date=11 February 2012 |url-status=live |archive-url=https://web.archive.org/web/20110430160025/http://www.ucmp.berkeley.edu/history/linnaeus.html |archive-date=30 April 2011}}</ref> Other [[naturalists]] of this time speculated on the evolutionary change of species over time according to natural laws.

In particular, [[Georges Cuvier]] insisted that species were unrelated and fixed, their similarities reflecting divine design for functional needs. In the meantime, Ray's ideas of benevolent design had been developed by [[William Paley]] into the ''[[Natural Theology or Evidences of the Existence and Attributes of the Deity]]'' (1802), which proposed complex adaptations as evidence of divine design and which was admired by Charles Darwin.<ref name="Darwin91">{{harvnb|Burkhardt|Smith|1991}} * {{cite news |url=http://www.darwinproject.ac.uk/letter/entry-2532 |title=Darwin, C.
