Introduction to an Evolutionary Breakthrough
In the mid-19th century, Charles Darwin proposed a radical idea that transformed our understanding of life on Earth: the theory of natural selection. This theory, first detailed in his seminal work, On the Origin of Species, suggests that species evolve over time through a process of natural selection, where individuals with advantageous traits are more likely to survive and reproduce.
Key Concepts
- Variation: There is a natural variation in traits among individuals within a species.
- Inheritance: Some of these traits are heritable and can be passed on to future generations.
- Selection: Individuals with traits that provide a survival or reproductive advantage are more likely to pass these traits on to their offspring.
Impact on Science
Darwin's theory has had a profound impact on biology, influencing diverse fields such as genetics, ecology, and behavior. It provided a framework to understand the complexities of life, pointing to common ancestors and the branching tree of life.
