Document Summary
Evolution- gradual change of populations or organisms over time. Changes that happen in a lifetime are not evolutionary. Proposed that plants/animals follow a specific organization and have fixed characteristics. Created ladder like classification system (scala naturae) , cannot move up or down the ladder. Leonardo da vinci drawing of human body, how it was divinely created. During these discoveries, new cultures and resources discovered, as well as new species. Some of these organisms were familiar, but something was different. As this occurred, it put into question about the different types of life. 18th century life might not have been fixed since creation. Linneaus- organized the organisms, for the greater glory of god. Leclerc if organisms are perfectly created, why are there vestigial structures? (parts of the body that do not have function) e. x. tailbone. Argued that ancestor must have used these vestigial structures at one point in time.
