Document Summary
Linnaeus was a creationist and an advocate of the principle of fixity of. Species: god created all species, and species were immutable and unchangeable after the creation. Theory of inheritance of acquired characteristics (first explanation of how a species can change over time) Continued use of an organ leads to an increase in its size and functional capacity, whereas disuse leads to its degeneration and loss. Changes in an organ that occur during ones lifetime are inheritable and can be passed to ones offspring. All organs in the body were harmonious and by changing one of the organs in the body it would have a negative effect. In the past, there were a series of sudden, violent geological and climatic changes that led to the extinction of animals in the affected region. After the cataclysm subsided, the region was repopulated by animals from neighboring areas that were similar in appearance- but not identical with-those that went extinct.
