Why is the giraffe's neck so long? Can they only eat from trees?
According to Darwin's theory of evolution, giraffes were "short-necked deer" long ago. Suddenly one day, several mutated deer grew longer necks, and the height advantage allowed them to eat higher food. When food is in short supply, short-necked companions are trapped by famine, and a few long-necked people survive. As a result, generation after generation, the giraffes of this family have multiplied to this day, and they all grow big and tall. But anti-Darwinian naturalists asked why the necks of other grassland herbivores didn't get longer and starved to death. Moreover, the neck becomes longer and bigger, and the corresponding body shape should also become bigger from childhood. This requires them to eat more food in the case of drought and famine, which contradicts the theory of evolution.
There is no authoritative answer to why giraffe's neck is so long. Now the accepted view is sexual selection. Male giraffes often fight with their long necks, hit each other with the strength of their necks, and even break each other's spines. Women's necks are relatively short and generally stop growing at the age of ten, while men's necks can continue to grow for more than 20 years.
The photographer photographed a giraffe with a broken neck in Africa. It turned out that this male giraffe was seriously injured in the neck when competing with his companions for the opposite sex, but it could survive tenaciously in the wild without drugs and drugs. Profile proves that giraffes use neck struggle to choose mating partners. Some scientists also believe that giraffe's long neck is used to cool down. During the day, the giraffe will face the sun, which will not only reduce the heat radiation it gets, but also help to dissipate heat. However, these are scientists' speculations, and new ideas may emerge in a few decades. ...
