The giraffe


The specific pattern on the fur of the tallest creatures in Africa transmitted from mother to giraffe pups is an interesting topic of study. Giraffe puppies inherit fur stains from the mother, being similar to that of her. According to Science News, their size and shape can influence the chances of survival of giraffes in the wild. Giraffes, like tigers, zebras and jaguars, are covered by a certain model that helps to adjust the temperature and camouflage. In the past the experts thought that animal patches or streaks appear in random areas or are influenced by environmental factors. But specialist Derek Lee of Pennsylvania State University has approached a new hypothesis that suggests that the fur of these animals is inherited from their mother.His team photographed for four years the fur of 31 giraffes and their offspring. The images that were analyzed by a software helped the specialists compare the model for each pair, depending on 11 features, including the shape of the stains, the size and the color. The roundness and fineness of the edges were extremely similar between mothers and pups suggesting that the fur model is inherited. The specialists have determined that puppies with the least regular, but large spots have the greatest chances of survival in the first year of life.




What about the long neck?


Giraffe is the tallest animal, but scientists fail to explain how they got their long neck. A famous French zoologist, Jean Baptiste de Lamarck, has a theory that the neck of the giraffe was, in the past, much smaller. Lamarck thinks that the neck of the giraffe has elongated because of the tendency to target the trees on the top of the trees. But other scientists do not accept Lamarck’s theory. It should be noted that the giraffe is normally not larger than an average horses. They can reach even six meters in high, thanks to the leg and neck lengths. The neck of a giraffe has only seven vertebrae, just as we find in humans. But every vertebra is much longer than in humans and that is why the neck of a giraffe is very stout. If she wants to drink ground water, the giraffe must stretch as long as possible to reach the ground. The strange appearance of the giraffe allows her to obtain the necessary food. She feeds only on greenery, and as in African savannah there is very little greenery, the long neck allows the giraffe to reach the leaves of the top of the trees. A giraffe’s tongue has an average of 46 centimeters in length and can be used with so much skill that the giraffe reaches the hardest accessible leaves. The giraffe also has a long upper lip allowing it to rip as many leaves as possible. The giraffe can be protected in several ways. First, the color allows it to hide in tall bushes or trees. It has an extremely developed sense of hearing. It has a well developed olfactory sense. In addition, the giraffe can develop a speed of up to 50 kilometers per hour, being faster than any horse. When attacked, the giraffe can hit the back of his legs or hit his head like a baroque. Even a lion is attacking a giraffe carefully, often overhanging her back.
