Study Notes
Dr. Kettlewell
- British geneticist known for studying the peppered moths' adaptation to environmental changes.
Impact of the Industrial Revolution
- Industrial revolution increased the frequency of dark 'carbonaria' moths due to pollution.
- Light 'typica' moths became more visible to predators, leading to a decline in their population.
Predation on Moths
- Moths are primarily preyed upon by birds, which impact their population dynamics.
Causes of Color Variation
- Natural selection drove the transition from light to dark moth varieties.
- Air pollution darkened tree bark, making dark moths better camouflaged and thus less vulnerable to predation.
Moth Varieties
- 'Typica' moths: light-colored, typically white, more visible against darkened environments.
- 'Carbonaria' moths: dark-colored, ranging from brown to black, evolved for better survival.
Survival Strategies of Adult Moths
- Adult moths avoid predators by being nocturnal and seeking refuge in trees.
- Camouflage plays a critical role in their survival, allowing them to blend into their surroundings based on their color.
Natural Selection Explained
- Natural selection is the process by which the fittest individuals survive, reproducing and passing advantageous traits to their offspring.
