Study Notes
Accumulation of Variation During Reproduction
- Reproductive processes produce new individuals with subtle differences, even in asexual reproduction.
- Sexual reproduction maximizes the number of successful variations.
Creation of Diversity over Succeeding Generations
- A single organism can give rise to multiple individuals with subtle differences in each generation.
- Each individual in the next generation inherits differences from their parents and introduces new differences.
- The number of variations increases exponentially over successive generations.
Inheritance
- Inheritance provides a common basic body design and subtle changes from the previous generation.
- The next generation inherits differences from the previous generation and introduces new differences.
Figure 8.1
- Asexual reproduction results in minimal differences between offspring, with only minor variations due to DNA copying inaccuracies.
Variation and Survival in the Environment
- Not all variations have equal chances of surviving in their environment.
- The nature of variations determines an individual's ability to survive and thrive in their environment.
