Dogs
are mammal species that could be used as a pet which has developed into
hundreds of races with the diversity of its variations. From
various existing sources, especially grandparents yahoo and google, it
can be concluded that in fact the dog still has a kinship with wolves
race. Let's look at this article and for our next article we can see About Dogs In Heat continue to follow updates from this blog article.
This assumption is reinforced by the discovery of fossils and DNA testing that has been done by experts. The
studies were carried out to explain that the dog races and race since
wolves began to split up the wolves adapt to-eat foods are eaten by
humans.
A study conducted by experts proved that the presence of wolves adaptations foods that eat human food cause wild wolves would be a benign grandmother moang dog and eventually make friends with humans. Habits of wolves that eat human food since men began to enter the plant, which eventually became genetically alter animals genetically wolves that today we call the dog. Differences in the genetic code of a dog and a wolf was found by researchers from Sweden, Norway, and the United States. This study suggests that there is a difference of 36 genes that showed a part of adaptation that occurs in wolves were the ancestors of the dog. Some parts were changed related to brain function, including the development of the central nervous system, which means wolves and dogs have different behaviors. Besides differences in three other genes that successfully revealed differences in genes that are associated with the digestive system. Still we continue article About Dogs continue to follow this article.
Types of dogs that exist in the modern era is a wild dog that is very much different from their wild ancestors. No dog has now been turned into animals which could serve as a tame pet and close to the human beings who have a wide range of privileges on sight, hearing and smell. Changes in shape.
The geologists concluded that the evolution of dogs occurred in 4 stages of times, namely: the Paleocene, Oligocene age, the age of the Miocene, and Pliocene age. In the Paleocene there are two kinds of animals that are part of the evolution of dogs, namely Miacis and cynodictis. Miacis a small animal with a long body and tail and too short. Examples such as the weasel (ferret), civet, hyena (coyotes), and cats. Physical characteristics Miacis is scalloped like carnivores (meat eaters) and runs like a bear. Small but larger brains compared to creodont that have disappeared over the last 20 million years. Creodont is a kind of meat-eating animals whose size is slightly larger than the mouse. Cynodictis an animal that lived during the Paleocene who have physical characteristics: small and slender body with the complete number of teeth as many as 42 pieces. Completeness of these teeth are prominent features of cynodictis. Along with the development time and age, these two types of animals to adapt and proliferate at this time leaving descendants who would be known as sable. Therefore, raccoons often called living fossils. Walawpun have evolved over 40 million years but it has not changed.
Entering the Oligocene era (approximately 35 million years ago), cynodictis still shaped animal with a long body and short legs, while Miacis widened evolved different kinds of dog sizes. Of offspring, Miacis developed into bear-like dogs, hyenas, cats, and dogs. These dogs are descendants survive to this day.
Beginning of the evolution of a real dog, who became the first family Canidae, occurred about 20 million years ago, at which the phase geologists call the Miocene era. Existing evidence suggests that at the time it was discovered fossils of animals similar to dogs. The animal has a smaller jaw jaw than the current dog called mesocyon. At this time cynodesmus grown to raccoons and weasels. Cynodesmus eventually evolved into tomarctus. Tomarctus is the nation's large dog that has a long jaw and brain are also great. Physical appearance is similar to a dog at the moment and considered the ancestors of the family Canidae such as canis, jackal, wolves, foxes, and hyenas.
Finally the Pliocene era, form the dog has been like this now. This happens 5-7 times sektar million years ago. These animals are walked on four legs which turned out to be one of his spurs. During this period, found Etruscan. According to the results penilitian, Etruscan is a direct ancestor of dogs and wolves.
