which best illustrates a result of natural selection?\no a bat that is born with a wing that is missing the…

Brief Explanations:

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 an example of natural selection as giraffes with longer necks had an advantage in reaching food and were more likely to survive and pass on their genes. A bat with a missing - web wing is a genetic defect, dark - colored hares in a snowy area are less adapted (not a result of successful natural selection), and mosquitoes transmitting disease is about their role in disease spread, not a classic example of natural selection.

giraffes having increasingly longer necks over time
