Study Notes
The Theory of Evolution by Natural Selection
- Charles Darwin and Alfred Russel Wallace independently conceived the theory of evolution by natural selection.
Evolutionary Processes
- Mutation: changes in DNA sequence
- Genetic drift: random changes in gene frequency
- Gene flow: movement of genes between populations
- Natural selection: differential reproduction of individuals with favorable traits
The Main Idea
- The theory of evolution by natural selection proposes that populations evolve over time through the accumulation of adaptations that enhance survival and reproduction.
Darwin's 'On the Origin of Species'
- The book primarily discussed the idea of evolution through natural selection, providing evidence from various fields including biology, paleontology, and geology.
Observable Facts Supporting Evolution
- The fossil record: showing a pattern of gradual changes in life forms over time
- Comparative anatomy: similarities and homologies between different species
- Biogeography: distribution of species across different regions and continents
- Molecular biology: similarities in DNA and protein sequences between different species
