Question

Pheasants do not feed their chicks. Immediately after hatching, a pheasant chick starts pecking at seeds and insects on the ground. Based on your understanding of animal behavior, what is a reasonable explanation for these observations?A. Pecking is an example of associative learning.B. Pecking is the result of imprinting during a critical period.C. Pheasants learned to peck, and their offspring inherited this behavior.D. Pheasants that pecked immediately after hatching had the highest survival and reproductive success

Answer 1

D. Pheasants that pecked immediately after hatching had the highest survival and reproductive success

Step-by-step explanation:

This means that behavior of pecking increased their survival and reproductive success and become favorable by natural selection.

Natural selection is evolutionary mechanism which favours traits (structures, behavior) of an organism that help him survive and reproduce. In the example, above, pheasants that pecked survived and that was the favorable trait by natural selection.
