The Greeks developed -or perhaps only broached- the major fields of philosophy. However, if there is a field of knowledge that is genuinely new, it is that of evolutionism.

Since Lamarck’s Philosophie Zoologique, and especially since Darwin’s On the Origin of Species, all knowledge pertaining to life is in debt with the Englishman’s main idea that all life forms come from common ancestors and that they are selected in a hazardous way by nature.
