Question

in several species of birds, the males show off their bright colors and long feathers. the dull - colored females usually pick the brightest colored males for mates. male offspring inherit their father’s bright colors and long feathers. which statement best explains how this behavior will likely influence future generations of male birds?
a. the traits of future male birds will vary randomly, since mate selection is unrelated to inherited physical characteristics.
b. males birds will likely lose these bright colors and long feathers, because these traits attract predators and reduce survival.
c. more generations of male birds will likely become by brighter and have longer feathers, because these traits increase mating success and are passed on to offspring.
d. future generations of male birds will become duller in color, since females are less likely to be influenced by appearance over time.

Explanation:

The question is about how the mating behavior (females picking brightest males) influences future male bird generations. The key concept is sexual selection: traits that increase mating success (bright colors, long feathers) are passed to offspring. Let's analyze options:

• First option: Claims mate selection is unrelated to inherited traits, which is wrong (traits are heritable).
• Second option: Says bright traits attract predators (not supported here; the focus is mating, not predation).
• Third option: States males with brighter, longer feathers (traits increasing mating success) will be more common as these traits are passed on. This matches sexual selection.
• Fourth option: Says males will become duller, but females pick bright males, so bright traits should increase, not decrease.

So the third option is correct.

Answer:

The option "Human generalizations of male birds will likely become by brighter and have longer feathers, because these traits increase mating success and are passed on to offspring" (assuming this is the third option in the list, with the correct reasoning as above).
