The Evolution of the Evolution Theory
The Theory of Evolution according to the Scientific Method
1.. Observation and Questioning
1831: Darwin joined a 5 year expedition and begins developing ideas as a result of his experience. He is already aware of adaptations of life for different environments.
1835: The HMS Beagle reaches the Galapagos Islands.
1836: Darwin returns back to England.
2.. Hypothesis and 3.. Experimentation
1837: Hypothesises that the environment evokes adoptive changes in species tested. Darwin starts his first notebook on evolution. He finds evidence from his study of the fossil record: he observes that the fossils of relative ages are more closely similar then those of wildly different ages.
4.. Sharing findings with others
1858: Alfred Russell Wallace concurs with Darwin’s findings.
1859: Darwin publishes – ‘On the origin of species by means of natural selection’.
1871: Darwin publishes – ‘The decent of man’ where Darwin applies the theories of evolution to humans.
1872: Darwin publishes – ‘The expression of emotions in man and animals’
1873: Darwin publishes a book about human evolution, sexual selection and the decent of man. Professional and public anger starts decreasing.
1876: Darwin publishes – ‘The effects of cross and self fertilisation in the vegetable kingdom’.
1881: The last book written by Darwin is published – ‘The action of worms’.
5.. Verification by others.
Scientific advances helped to provide more testing after Darwin’s death in 1882. Mendel and De Vries continued to work on gene mutation. Biochemistry and molecular biology advances provided supported evidence for Darwin’s Hypothesis.
6.. Production of theory.
20th Century: The evolution theory had enormous difficulty, winning acceptance from the scientific community, but by the middle of this century it’s updated version “modern synthesis” was accepted as a valid theory.
