which best illustrates a result of natural selection?\n 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. Giraffes with longer necks had an advantage in reaching food, so over time, the trait of longer necks became more prevalent through natural selection. A bat with a missing - web wing is a genetic defect, dark - colored hares in a snowy area are less adapted, and mosquitoes transmitting disease is not a direct illustration of natural selection's result in terms of adaptation and trait prevalence change.

Answer:

giraffes having increasingly longer necks over time
