Giraffe that does stand out from other animals

Giraffe that does stand out from other animals. At the zoo or in their natural habitats in the vicinity of Central Africa, the high towering over other animals, and is the second largest land animals that are still alive until now (the largest African elephant). Long-neck giraffe has dazzle observers for several years. 'How could a long neck? " they asked.

In observation of shoulder-high 3 meters (10 feet) long neck giraffe stretched 2.5 meters (8 feet) to the limit, and coupled with a long tongue and measuring almost 1 foot to reach himself with an acacia tree branch that looks unachievable , and some people may believe that the process of stretching the lead to the growth of the giraffe's neck. But actually, what a giraffe is able to add something for the height?

If one feature is changed, is not this going to affect everything? Let us consider the giraffe.

Giraffe is a mammal, therefore much of the same anatomic structure with what mammals have as well. As with most mammals, giraffes have seven neck bones. What if he does not have seven bones in the shoulder and the base of the skull? Short neck supporting the head man of a very balanced with upright posture and a very small business. Large giraffe head height should be detained at any time. By the time he was upright, almost half of the neck muscle that weighs about 225 kilograms (500 pounds) is in tension. The amount of muscle required is directly related to the number of joints that must be seconded. Reducing joint until only two (in the skull and at the shoulder) will reduce weight by a lot and need energy for survival also decreased. If this lack of food makes the neck to change, would not the number of neck bones and joints changed also in the process of evolution? Of course the problem in this neck design is the loss of flexibility, and also improve the ability of cracks in many, if the giraffe was receiving a blow to the head or neck.

In the same things, have neck joints which are connected with the complex will cause a specific purpose - a higher energy consumption and the need to support more muscle mass. This will cause the focus of the giraffe to move to the front of the front legs when the head faced straight ahead, and also causes the rear legs flying off the ground - in a fairly strong presumption front legs. Seven neck bones is excellent design.

With his head held high in the air, a large giraffe heart can pump blood must be filled with enough oxygen to within 3 meters (10 feet) to the brain. This will cause a problem (involving too high blood pressure) when the giraffe was lowering his head when he drank water, if not for a unique group of artery walls, valves around and prevent the collection of blood, a network of small blood vessels (the rete mirabile, or 'an amazing network'), and signal detection pressure sufficient to maintain blood flow to the brain in the correct pressure. Including those who think this is just 'adaptation to high gravitational pressure in the cardiovascular system', the giraffe is a unique animal.

ADJUSTMENT TO GRAVITY giraffe's heart is probably the most powerful among the other animals, because about two times higher than normal blood pressure is needed to pump blood through a long neck to the brain. With high blood pressure, only special design features to prevent him from 'his brain explode' when he bent down to drink water.

The fact that the same amazing is not his blood gathered in the foot, and giraffe abound not bleed when her feet hurt. The secret is a very hard skin and tissue on the inside that prevents the accumulation of blood. Combination skin has been studied by the NASA scientists in their development of clothing for astronauts. What is also useful to prevent major bleeding found in all blood vessels in the foot giraffe is so internal.

Capillaries that reach up to the surface is very small, and red blood cell size of about one-third of the size of human beings that makes blood flow possible. It certainly became clear that the whole aspect of the giraffe are all interacting with each other and depend on each other with a long neck.

But there's more. Red blood cell size smaller allowing a larger surface area and a higher oxygen absorption and faster in the blood. This helps maintain an adequate oxygen supply to the extremities, and also in the head.

Her lungs work together with heart to equip giraffe with enough oxygen, but in a way unique to giraffe. Lung size giraffe eight times greater than that of humans, and breathing rate of about one-third of the human. Breathing more slowly is important to replace the volume of air that is needed without causing the skin to the trachea rough giraffe that many times over and over 3.6 meters (12 feet). When animals breathe fresh breath, the breath before that had run out of oxygen can not be removed completely. For the giraffe, this problem is compounded again by the long trachea and who will leave with a lot of dead air, more than one human breath. Solution is inhaled air must be sufficient to make the 'bad air' in a small percentage of the overall total. It is a matter of physics that have been solved by a giraffe.

BIRTH Giraffe

For surprisingly, the birth of giraffe resolve the matter in the Intelligent Design (Design Intelligence). A new-born whelp fallen and living from a height of 1.5 meters (5 feet), because his mother was not able to squat on the ground comfortably, and stay under at the time of delivery would be an invitation to a lion or other predator to attack the mother. For all mammals, the size of the head is not balanced with other body size, and this is a challenge to reduce the child through the womb.

Baby giraffe gets additional challenges, which have long necks and fragile to connect with a whole new body that weighs 70 kilograms (150 pounds). When his head came out first, her neck would crack when the rest of him fell on top of the neck. If you head out the very latest, must also fractured his neck due to his weight pull her head out of his mother. Such an impasse resolved with rear hip quite smaller in size than the front shoulder, and neck length sufficient size to allow the head through the womb and landed in the rear flank. The hind legs fall out first to keep other parts of the body. His head was seconded and dibantali by the pelvis back, and neck quite flexible, allowing lengkokan sharply around the front shoulders.

This is a perfect solution, which is impossible in the other or a combination of different neck length. A few minutes later, the child with a graceful giraffe is standing between her legs. From birth to adulthood in just four years, his neck grew from one-sixth to one-third of the total high giraffe. This growth required the animal to overcome problems and to submit to his feet altitude down to drink water. Foods child giraffe for the first year is usually a rich mother's milk, and which can be reached easily.

In terms of ecology, the giraffe is very suitable to the environment. There is a need for a tree trimmer to prevent the lush trees that grow quickly from skimming the ground and kill the grass essential that provide food for animal pasture. Also there will need guards who can see from above the tall grass and looked at the predatory cat movements. Giraffes are not only high and able to do this, but it also has the vision and character who wants to know. After warning other animals with a few hisses tail, a giraffe with a gallant take a step away from danger. Higher great body, a strong crust, a lethal kick back, and step length and speed make an adult giraffe prey that are not desired by other carnivores.

To say that all this is probably the result of evolution to a class of animals, with the lack of other things that relate and can be thought of, and be very good just because one might expect is the lack of food at the surface, is impossible. Should not the others who also ate at the surface, which is also impervious to the big cats, and who also experienced the same cosmic radiation, has reached the heights like a giraffe?

Interestingly, there are other animals who are eating from the tree. Deer gerenuk (Litocranius walleri) from Africa has the longest neck of the deer family, has a long tongue, and eat leaves from trees while standing on its hind legs. Markhor goat (Capra falconeri) from Afghanistan to climb trees as high as 25 feet to eat the leaves of a tree. Other mammals also wants the leaves of the tree but none of them would be a giraffe, and giraffe, of course, is not derived from animals 'less than a giraffe'.

We can not know that the condition was the same as now, but the theory of "the need for survival with higher growth for the food" is a little more than post hoc speculation (a mistake in the argument), just as Darwin's explanations about the various animal species. This ensures the fossil record, and the unique and stunning designs are visible from these animals to prove this. Praise, glory, and majesty turned to the Creator of this giraffe.
