Question

task card 4: the architects progress
scenario: a bird builds its very first nest using small twigs. the next year, after experiencing a heavy storm that blew the first nest away, the bird uses mud and stronger grass to build a better nest in a more sheltered spot.

1. question a: explain how this scenario shows a combination of both inheritance and the environment.

Explanation:

1. Inheritance component: The bird's instinct to build a nest at all is an inherited, species-specific behavior—this innate drive is passed down genetically, allowing it to construct its first nest without learning.
2. Environment component: The heavy storm (an environmental event) destroyed the first nest, creating a selective pressure. The bird's subsequent choice of stronger materials (mud, sturdier grass) and a more sheltered spot is a behavioral adjustment directly influenced by this environmental challenge, demonstrating learning from environmental feedback.
3. Combination: The bird relies on inherited nesting instincts to initiate behavior, but modifies that behavior based on environmental experience to create a more successful nest.

Answer:

This scenario combines inheritance and environment as follows:

• Inheritance: The bird has an innate, genetically passed-down instinct to build a nest, which allows it to construct its first nest using twigs without prior learning.
• Environment: The destructive heavy storm (an environmental factor) acts as a stimulus. The bird responds by adapting its nesting behavior—using stronger materials (mud, sturdy grass) and choosing a more sheltered location—to improve the nest's durability, showing it learned and adjusted based on environmental feedback.
• Together, the inherited nesting drive provides the foundation, while environmental experience shapes the improved nest-building strategy.
