Explanation: Darwin was the first to propose that long necks evolved in giraffes because they enabled the animals to eat foliage beyond the reach of shorter browsers. Darwin himself wrote %it seems to me almost certain that an ordinary hoofed quadruped might be converted into a giraffe.' He speculated that four-legged animals with longer and longer necks would be capable of reaching higher leaves and vegetation. |
