Why do giraffes have long necks?

Many giraffe observers have noticed their extremely long necks, which led to a great speculation about why giraffes had long necks. There are a number of theories, but the most likely explanation is that giraffes with longer necks are more successful in the fighting and the giraffes that win fighting are able to reproduce. Obviously, the famous giraffe neck developed from the desire to win the battle and centuries of natural selection for a longer, stronger necks led to a modern giraffe. As a result of the development of long necks, the giraffes had to perform several adaptations to survive, including the development of a very strong circulatory system that pushes blood from the heart into the brain. Given the physical stress created so that it has such a long neck, there is no clear biological advantage for giraffes as demonstrated by the general lack of animals with a long throat in the world.

Some people claim that giraffes have long necks to reach high leaves on trees and shrubs,Under the argument that the ability to achieve high leaves would allow giraffes to access food during the dry period when the leaves are rare. Scientists who studied giraffe feeding found that giraffes actually tend to go low, reduce their heads to eat. In wet seasons, when there are a large number of leaves, giraffes can pass on high leaves.

other people suggested that giraffes have long necks to clearly see the upcoming predators. Biologists largely rejected this theory to a large extent and claimed that if the ability to see over long distances was such an advantage, more animals would have long legs and necks. While the fact that giraffes have a long neck to find out predators is unlikely that giraffes would develop long necks specifically for this purpose.

giraffes and many of their relatives are fighting by basically defeating necks and heads, in a process known as the neck. Male giraffes use their necks as deadly weapons, whipping the neck of the wheelsEm and their opponents with heavy skulls. The longer and stronger the neck, the more they are packed, so it seems that the giraffes have long necks to fight more efficiently.

For those who are interested in other factuals about these African mammals, in addition to long necks, giraffes also have very long languages. Animals use their tongues to achieve acacia tree thorns to achieve leaves without hurting their muzzle.
