How does Dawin's theory of natural selection explain giraffes' long necks?
Something along the lines of:
Due to natural variation, the ancestors of modern giraffes would have had necks of different length. Giraffes with longer necks would have been able to reach more food than those with shorter necks.
As a result, the long-necked giraffes were more likely to be healthy and live to produce more high-quality offspring.
This, in turn, would increase the chances of their long-necked characteristic (an adaptive trait) being passed on to future generations.
