It is one reading of the quote, not the author's own explanation. Fitness rises proportionally to how much genetic variation exists in a population at a given moment. **In simple terms:** More genetic variation means faster fitness improvement. Key Takeaway Preserve genetic diversity. Themes evolution genetics population dynamics Mood analytical objective Type scientific educational When to use this quote - conservation breeding - crop improvement - medical genetics - environmental change Key Concepts natural selection genetic variance fitness landscape Questions to Reflect On - How does maintaining diversity affect long‑term adaptation? - What limits the rate of fitness increase?
