Question

which best illustrates a result of natural selection?
o a bat that is born with a wing that is missing the web
o dark - colored hares living in a snowy area
o mosquitoes that transmit disease to humans
o giraffes having increasingly longer necks over time

Explanation:

Natural selection is the process by which organisms better adapted to their environment tend to survive and reproduce more offspring. Giraffes having increasingly longer necks over time is a classic example. Longer - necked giraffes had an advantage in reaching food sources that others couldn't, so they were more likely to survive and pass on their genes for long necks. A bat with a missing web in its wing is a genetic defect, dark - colored hares in a snowy area are less likely to survive due to predation (not a positive result of natural selection), and mosquitoes transmitting disease is a description of their function rather than a result of natural selection in the context of adaptation for survival.

Answer:

giraffes having increasingly longer necks over time
