Study Notes
Early Theories
- Aristotle proposed an evolutionary concept in the 4th century BC.
- He believed that living things evolve towards a higher form.
- The idea of immutable species, that species are unchanging, was widely accepted after Aristotle.
Lamarckism
- Jean-Baptiste de Lamarck developed a theory of evolution called Lamarckism.
- It suggested that acquired characteristics are passed on to offspring.
- This theory is now understood to be incorrect as acquired characteristics are not heritable.
Darwinism
- Charles Darwin was a British naturalist who developed his theory of species origins while traveling to South America, the Galapagos Islands, and other regions.
- Observed that populations increase exponentially until limited by the environment.
- He saw the struggle for survival, a competition for resources.
- Darwin proposed that organisms with beneficial traits are more likely to survive and reproduce.
- These advantageous traits are then passed on to offspring.
- Unfavorable traits tend to be eliminated.
