Question

Which one of the following is a proximate explanation for grouping in animals?

• A. Animals in groups face a lower risk of predation.
• B. Animals form groups to forage efficiently.
• C. Groups can navigate their environment better.
• D. Groups form when individuals show attraction to others.

Hint:

Proximate explanations focus on the immediate cause of behavior, such as individual attraction or efficiency, while ultimate explanations address the evolutionary advantage of that behavior.

Answer 1

The Correct Option is B

Step 1: Understand proximate explanations.
Proximate explanations refer to immediate, mechanistic factors that explain behavior. In the case of animal grouping, the proximate cause often includes behaviors such as attraction to others or benefits in foraging efficiency.

Step 2: Evaluate options.
Option (A): This is a more ultimate explanation, explaining why grouping may be advantageous in terms of evolutionary fitness, rather than a proximate cause.
Option (B): Correct, animals often group together to increase foraging efficiency, a proximate behavior.
Option (C): This is more of a consequence or benefit of grouping, not the proximate cause.
Option (D): Correct, animals may form groups due to attraction to others, which is a proximate explanation for grouping.
Hence, the correct answers are (B) and (D).
