Introduction
- Charles Darwin (1809–1882): A British naturalist who proposed the theory of evolution by natural selection, which became the foundation of modern evolutionary studies. His work On the Origin of Species is a landmark in biology.
Task
- Task: To understand why species vary across different environments and how life forms change over time.
Process
- Process: Conducted 5-year field research on the HMS Beagle (collecting specimens, observing ecosystems in South America, Galápagos Islands, etc.); analyzed data for decades, studied breeding practices, and synthesized ideas from geology and economics.
Evaluation
- Evaluation: Initially controversial, but his theory of evolution by natural selection is now widely accepted as the unifying framework of biology, supported by fossil records, genetics, and comparative anatomy.
Conclusion
- Conclusion: All living organisms share common ancestors, and traits that enhance survival and reproduction are passed on through generations (natural selection drives evolutionary change).
Credits
- Other Works: The Descent of Man (1871) explored human evolution and sexual selection, while The Expression of the Emotions in Man and Animals (1872) linked human and animal behavior.
