- Natural selection
- Use and disuse of organs
- Inheritance of acquired characters
- Species change over time
Hint:
The concept that states that inheritable characters that help an organism to survive and produce offspring become more common among a population over time.
The correct answer is: Natural selection
- Natural selection was proposed by Charles Darwin and not Lamarck
- Natural selection as stated by Darwin is "heritable traits that help organisms survive and reproduce become more common in a population over time"
- According to the concept, the species that adapts itself to the changing environment is considered fit to survive
- This helps in creating variations among living populations
