Document Summary

Natural theology belief of god and divine creation. Natural theologists believed in intelligent design/divine creation: somebody is in charge of life and nature. They believed the earth to be only a few thousand years old. God had formed all species exactly the way they are. Organisms were separate entities and had no relationship to each other whatsoever. Extinct species seen in the fossil record were the results of catastrophes such as floods. Belief in the great chain of being: species were ordered from most simple to most complex and perfect, this resembled a ladder. No way nature resulted in the complexity of organisms. Their presence can only be explained by purpose and design known as teleology. Evolutionary theory natural world is steadily changing and organisms have diverged from common a(cid:374)(cid:272)estors, a(cid:374)d that the(cid:455)"(cid:448)e (cid:271)ee(cid:374) tra(cid:374)sfor(cid:373)ed i(cid:374) geologi(cid:272)al ti(cid:373)e. Thus, all organisms are related and their relationships resemble a branching tree rather than a ladder.
