About Charles Darwin’s Theory of Evolution:
- Darwin in his Theory of Evolution describes how organisms evolve over generations through the inheritance of physical or behavioral traits.
- The mechanism that Darwin proposed for evolution is natural selection.
- How Natural Selection Happens?
- Individuals with traits that enable them to adapt to their environments will help them survive and have more offspring, which will inherit those traits.
- Individuals with less adaptive traits will less frequently survive to pass them on.
- Over time, the traits that enable species to survive and reproduce will become more frequent in the population and the population will change, or evolve.
- Natural selection depends on the environment and requires existing heritable variation in a group.
- Through natural selection, Darwin suggested, genetically diverse species could arise from a common ancestor.
