Study Notes
Darwin's Theory of Evolution by Natural Selection
- Proposed by Charles Darwin in 1859 in "On the Origin of Species"
- Revolutionized understanding of species origin and change over time
Key Components of Darwin's Theory
- Variation: diversity of traits within a population due to genetic mutations, recombination, and other processes
- Heritability: traits passed from parents to offspring
- Differential Reproductive Success: individuals with advantageous traits are more likely to survive and reproduce, spreading their traits within the population
Process of Natural Selection
- Organisms with traits better suited to their environment are more likely to survive and reproduce
- Passing advantageous traits to their offspring
- Gradual accumulation of favorable traits within a population over successive generations
- Leading to adaptation of species to their environment and diversification of life forms
Implications of Darwin's Theory
- Provides a unifying framework for understanding the diversity of life on Earth
- Has profound implications for fields including ecology, genetics, medicine, and conservation
