Why is a giraffe s neck so long

The giraffe's long neck is the result of natural selection.

The ancestors of the giraffe used their necks more and more in the struggle for food, survival and fighting, so that the neck of the giraffe gradually became longer and longer as the generations continued.

Charles Darwin, a British biologist and founder of the theory of biological evolution, believed that giraffes' long necks were the result of natural selection. In ancient times, giraffes' necks were long and short. When there is a drought, most of the plants on the ground dry up, and the rest is quickly eaten up by the animals.

And those long-necked deer can eat the leaves of the trees on high places, and they survive.

Because giraffes like to eat the leaves on trees, because the trees are relatively tall, giraffes need to stretch their necks to eat, so after a long time, the giraffe's neck is also stretched longer and longer, and finally it has become what it is today.

Giraffes are the tallest land animals in the world. Someone once measured a particularly large giraffe, which reached a height of nearly 6 meters. Giraffes have a strange appearance and an elegant body.

It is very alert and agile, with protruding eyes on its head that can simultaneously observe its surroundings, and its four long legs support its nearly one-ton body, and it can run at speeds of up to 60 kilometers per hour. In Africa, where grasslands and forests meet, they can be seen munching on leaves.

Giraffe habits:

The giraffe has a pair of large brown eyes, prominent eyeballs, can rotate around, has a wide field of vision, and has a tall body, like a living "lookout", can see movement in the distance. Giraffes run fast because of their long legs, which is also trained in the competition for survival.

When running, the posture is very special, first stretching the head and neck, and then retracting, swinging alternately, and the four-legged walking style is different from other beasts, that is, the two legs on the same side and the two legs on the other side alternately move forward, jumping forward. Running fast. Tall and long legs, limbs can be kicked in all directions, front and back, left and right, with a wide range of hits and great strength.

In fact, the necks of the ancestors of giraffes were not too long. In the early days, giraffes had to stretch their necks to eat the leaves in order to eat the leaves of the trees because they grew taller and taller on the earth. Giraffes with short necks died because they couldn't eat food for a long time, leaving giraffes with long necks.

The first impression of a giraffe is its long neck, and the giraffe's name is also derived from its neck, so why does a giraffe's neck grow so long?

Why Do Giraffes Have That Long Necks?

The French biologist Lamarck put forward the famous theories of "use in and waste and retreat" and "inheritance of acquired traits", believing that the area where the giraffe's ancestors lived was an arid zone due to changes in natural conditions, and the grass was scarce, and the giraffe had to eat the leaves on the tall trees to satisfy its hunger in order to survive, and in order to achieve this goal, it made special efforts to stretch its neck.

The giraffe's long neck and long legs also make it a great cooling tower. They live in the hot savannas, and due to their large surface area, which favors the dissipation of heat, they adapt well to their surroundings.

The lung capacity is also large, which is conducive to breathing fresh air and expelling exhaust gases. Because giraffes have long legs, they have difficulty drinking water. They must drink with their front legs outstretched or on their knees, and are easily attacked by other animals, so giraffes that live in groups often do not drink together.

Notes:

According to the fossil record, giraffes first diverged from the early Miocene deer family. The earliest fossils in the giraffe family are the Klimac giraffe and the Cansamoree giraffe. Later evolved into the ancient tragus, the ancestor of the giraffe in the early Miocene, with short horns and a short neck.

In the late Miocene, Gulin evolved into Saotherium. In the Pliocene, samoids were divided into two groups, okapi and the first modern giraffe.

One of the only two remaining members of the giraffe family, the okapi is a rare animal whose appearance roughly mirrors that of the Miocene giraffe. This is a representative species of the Sandfly family. The okapi lives in the tropical forests of the eastern Congo of Africa and retains many of its original features.

The first impression of a giraffe is its long neck, and the giraffe's name is also derived from its neck, so why does a giraffe's neck grow so long?

This one was given by God, and it should be that long. It's like people have one nose and two eyes, why do you say that?? Hehe.
