The giraffe has often been made the object of jokes. The giraffe is in fact the tallest animal on our planet earth. They can reach up to 5.5 metres tall, and their long legs carry them at speeds of up to 20 mph. Many biologists believe that the giraffe slowly developed by a gradual process of evolution. Let's think about some of the facts, to help us make up our minds.
Giraffes are browsers.
They nibble thorny branches well beyond the reach of other animals. The trouble with this idea is that the young giraffes are much shorter than their parents, and so if they could not reach the higher leaves, they would die. There would be no giraffes left in the world today. Yet it is surviving reasonably well with only a short neck. It shows no sign of evolving a longer one.
