Adaptations: How Species Evolve to Fit Their Environment

The video explains how living things adapt to their environments through natural selection. It uses examples like mangoes, bananas, and penguins to illustrate how species develop traits to survive in specific climates. The peppered moth is highlighted as a case study, showing how industrial pollution led to a shift in moth populations. The video concludes with a review and questions to reinforce learning.

Why do mangoes and bananas not grow in Antarctica?

• They require cold temperatures.

• They need warm, tropical conditions.

• They grow best in shaded areas.

• They thrive in dry environments.

What happens to traits that help species survive in a new environment?

• They become less common.

• They become more common.

• They remain unchanged.

• They disappear completely.

What is a key factor for the long-term survival of a species?

• Migration to new areas

• Development of adaptive features

• Increase in population size

• Reduction in food sources

What was the primary environmental change affecting the peppered moth during the Industrial Revolution?

• Increase in rainfall

• Deforestation

• Pollution from coal burning

• Rise in temperatures

How did the dark peppered moths benefit from the environmental changes during the Industrial Revolution?

• They migrated to a new habitat.

• They blended in with the polluted trees.

• They developed new feeding habits.

• They became more visible to predators.

What percentage of the peppered moth population was dark-colored by 1895?

• 75%

• 95%

• 10%

• 25%

What is causing the rise in the light-colored moth population today?

• New tree species

• More predators

• Reduction in pollution

• Increased rainfall
