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?
-
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.

Giraffe necks are the result of natural selection. In ancient times, the neck of the giraffe was not as long as it is now, and it mainly fed on grass on the ground, and in the process of species evolution and reproduction, there were occasional mutations to get a giraffe with a long neck, at this time, this variation was no different from that of a normal giraffe in terms of feeding. Later, with the deterioration of the environment, the grass on the surface can not meet the food requirements of all giraffes, they gradually shift their attention to the leaves of the trees, at this time the advantage of a long neck is reflected, the giraffe with a long neck can obtain a wider range of food, can get more food, therefore, the higher the possibility of surviving to leave offspring, the giraffe with a short neck has not mutated because of the feeding problem is gradually eliminated, just like that, after millions of years of evolution, the giraffe population, You can only see what we see now with a thin and long neck.

Natural selection, survival of the fittest.

Introducing the reasons for giraffes' long necks.
-
Species evolution results that help to eat fresher plants!
-
Giraffes have long necks that are able to split older and eat better leaves, which is the result of slow evolution. When you grow taller, you can eat plants that rise higher, and there will be less competition for this kind of collapse, so they evolved to have long necks.

Giraffe. It has a graceful, long neck and legs with distinctive markings on its body, which makes it instantly recognizable. Giraffes all have short horns on their heads.
and other mammals.
Similarly, the giraffe's flexible neck contains only 7 dorsal vertebrae.
But these bones are all elongated. Children should ask, why do giraffes have such long necks?
Giraffes have long necks and are definitely formed to adapt to their environment. The ancestors of giraffes lived in an environment without grass. In order to survive, they have to try to stretch their necks to eat leaves, so that from generation to generation, their necks slowly become longer.
There is also a saying that there are slight differences between the ancestors of giraffes, some have long necks, some have short necks, and over time, those with long necks can eat leaves, and those with short necks starve to death. In this way, the long neck is inherited, and it becomes a giraffe.
-
It is believed that the area where the giraffe's ancestors lived was arid due to changes in natural conditions, and pasture grass was scarce, and in order to survive, giraffes had to feed on the leaves of tall trees to satisfy their hunger, and in order to achieve this, they made special efforts to stretch their necks. As the organs that are often used are more and more advanced, the organs that are not used will degenerate, and the acquired traits can be inherited, so that the continuous change from generation to generation will gradually become longer for thousands of generations. So the giraffe's neck became longer, and it was passed down from generation to generation.
-
This is caused by the genetics of this species, so giraffes will have such long necks because they are also relatively tall, and their legs are also long, and the long necks can be eaten to be healthier.

Hello. Current morphology of plants and animals.
It's all about survival.
Slowly formed in evolution.
The so-called survival of the fittest.
There will be changes in the future.
Evolution is endlessly going on in nature.
Until the day the earth dies.
The neck of a giraffe is so long.
It's to be able to eat food from high places.
So slowly the neck is longer.
Giraffes have a normal blood pressure of 300, which is three times that of the average person! The heart also weighs more than 11 kilograms. >>>More
Biological evolution is one-way and there is no turning back. Once a certain evolutionary route has been chosen, it must be strengthened and perfected, and it cannot be reverted back to the original state. When organisms reproduce their next generation, they will select individuals with strong bodies and good genes, which is called sexual selection. >>>More
The one with the longest neck, haha! Happy Holidays!
It's seven pieces like a human. It doesn't have a long neck because it has more bones. The giraffe is an endemic animal in Africa, with a long neck, raised head, and the tallest male giraffe can reach a height of 6 meters, making it the tallest animal on land. >>>More
The reason why giraffes are able to carry blood through their long necks to their heads is due to the high blood pressure of giraffes. It was determined that the giraffe. >>>More
