Behavior and Natural Selection

Mr. Anderson discusses how behavior affects natural selection, using examples from plants and animals. He explains innate and learned behaviors, phototropism, photoperiodism, courtship in animals, and cooperation in pollination. The video highlights Darwin's contributions and the importance of measuring natural selection.

What was a significant limitation in Darwin's study of natural selection?

• He did not have access to modern technology.

• He lacked empirical data to support his theories.

• He focused too much on animal behavior.

• He ignored the role of environmental factors.

Which of the following is an example of a learned behavior?

• A plant's growth towards light.

• A baby chimpanzee's grabbing reflex.

• A bird's instinct to migrate.

• A chimpanzee using a tool learned from its mother.

How does phototropism benefit plants in a forest environment?

• It enables them to maximize light absorption.

• It allows them to grow taller than other plants.

• It protects them from herbivores.

• It helps them conserve water.

What is the primary factor that influences photoperiodism in plants?

• Amount of water

• Soil quality

• Length of daylight

• Temperature

What is the main purpose of a bowerbird's bower?

• To attract a mate

• To store food

• To shelter from the rain

• To protect from predators

How does co-evolution between flowers and insects benefit both parties?

• Flowers get protection from insects.

• Insects receive shelter from flowers.

• Flowers get pollinated, and insects get food.

• Insects help flowers grow taller.

What did Darwin predict about the orchid with a long nectar tube?

• It would adapt to have a shorter tube.

• It would eventually become extinct.

• It would attract a specific insect with a long proboscis.

• It would not be pollinated effectively.
