Give examples of structural and behavioral characteristics that might give selective advantages to an organism.
What will be an ideal response?
The principle of natural selection suggests that certain characteristics of an organism offer an advantage that allows the organism to survive and reproduce and to pass on that characteristic to its offspring. The coloring of an organism may allow it to blend into the background, thus escaping detection by predators. The capacity to remain still (i.e., freeze) may similarly allow an organism to avoid predation.
