1650-Irish archbishop James Ussher calculates the date of creation, based on the ages of biblical prophets. Using his calculations, theologians will identify the date of creation as on October 26, 4004 BC.
1778-Buffon publishes Les Epoques de la Nature, asserting that the Earth is a staggering 74,832 years old, and has existed long before the arrival of humans or any other form of life.
1804-Georges Cuvier suggests that fossils found in the area around Paris are "thousands of centuries" old. This casual observation pushes the age of the Earth well beyond its commonly accepted limits. Cuvier also publishes a paper explaining that the fossil animals he has studied bear no resemblance to anything still living, an unambiguous endorsement of the theory of extinction.
1953-Fiesel Houtermans and Clair Patterson publish independent estimates inferring the age of the Earth through radiometric dating of meteorites. Both estimates are over 4.5 billion years.
Things you should know about this site
This is not a comprehensive history of paleontology or biology, nor is it the result of systematic research. It's not the work of a professional scientist, educator or historian. It's just an eclectic collection of old illustrations and information.
Although this site focuses more on the history of science than on evolution, it treats evolution as a scientific fact, not "just a theory."
