THE GIRAFFE'S NECK

In the past, the head of the giraffe was very short. One day, some animals in the jungle decided to play hide-and-seek. The monkey said he would look for all animals

Every animal ran to hide, but Kirin could not find a suitable place to hide. He tried to get in by seeing the dent in the tree. But his neck was hit there. He tried to free himself, but everything was in vain. Giraffe begins to shout

Listening to the scream, all the animals came out of their hiding place. They pulled out the giraffe around the neck and extended it. Since then, the head of the giraffe is very long

Kirin's head: "At some point in the past, the giraffe needs to be in an environment hard to reach the top of the tree, you have to stretch his neck to eat.This will stretch your body. Will be handed down to the descendants of the next generation, which in turn will extend the head further and lengthen the head of the giraffe "The eagle's view is sharp." In the hawk group there are individual differences in visual forces. As well as the difference in feather color, in their food competition, people with sharper eyes can more easily find their baits (small mouse and mouse) and therefore it is better to get food successfully it can. A hawkian who saw sharp eyes tells this descendant to their descendants.

There are some assumptions about the origin of evolution and maintenance of the giraffe neck elongation. "Competitive browser hypothesis" was originally proposed by Charles Darwin and has just been questioned recently. This suggests that competitive pressures from small browsers such as kudu, steenbok, impla, etc. will lead the girls to gain access to food that impossible competitors can. This advantage is true because giraffes can feed up to 4.5 meters (15 feet) and even very large competitors like Kudu can only feed up to 2 meters (6 feet 7 inches). In a study by height, at a lower level, competition for browsing becomes more intense, and it is shown that giraffe becomes more efficient in the canopy (there are many leaves biomass per mouth). This study shows that maintaining a longer neck requires more nutrients, which endanger the long neck giraffe during food shortages.
