Study Notes
The Theory of Evolution and its Historical Background
- In science, the word "theory" refers to a large body of work that underlies the basic understanding of a scientific phenomenon, such as the theory of evolution.
- The theory of evolution refers to the totality of our understanding about the mechanisms of evolution and has been thoroughly tested and widely accepted as valid.
- Historically, ancient Greeks, including Aristotle, and Judeo-Christians believed that species were fixed and did not change, while Carolus Linnaeus believed in a divine order and rejected evolution.
- The theory of natural selection was preceded by mounting evidence supporting evolution and refuting the traditional viewpoint that species were fixed and did not evolve.
- Evidence supporting evolution includes biogeography, comparative morphology, and geological discoveries.
- Biogeography evidence includes the discovery of species with similar forms in different regions and the development of similar traits in organisms due to similar environmental pressures (convergent evolution).
- Comparative morphology evidence includes similarities and differences between body plans and body parts of different animal groups, such as homologous structures and vestigial features.
- Geological discoveries, such as fossil layers and gradual geological changes proposed by James Hutton and Charles Lyell, also pointed toward a relationship between different animals.
- Charles Darwin developed a theory of evolutionary adaptation by studying Galapagos finches and correlating variations in traits with environmental challenges.
- In the 1830s and 1840s, Darwin developed a theory of natural selection, which he co-published with Alfred R. Wallace in 1858.
- The breakthrough that changed the world came in 1859, when Darwin published his book "The Origin of Species," which introduced the theory of evolution to the public.
- Alfred R. Wallace independently developed a similar theory of natural selection and co-published it with Darwin in 1858.
