Charles Darwin's theory of evolution is primarily encapsulated in the concept of natural selection, but it can be expanded into several key ideas:
-
Variation: Individuals within a species exhibit variations in traits.
-
Inheritance: Traits can be passed down from parents to offspring.
-
Overproduction: Organisms tend to produce more offspring than can survive.
-
Survival of the Fittest: Individuals with advantageous traits are more likely to survive and reproduce.
-
Descent with Modification: Over time, these advantageous traits become more common in the population, leading to evolutionary change.
These concepts collectively explain how species adapt and evolve over generations.
