Evolution & Cat Domestication

!9# Evolution & Cat Domestication

Evolution has long cat ... more than men on earth. And when people finally showed up, let the cat on the right

Noah may have had cats, he built the ark for the flood, but they were the ancestors of what we know as the domestic cat in the world today? It can be confusing to think that everything is in the world, everything is always in the light of the trial so the opposite, ie fossil discoveries. I think the story of Noahunderstanding of greater importance than an enumeration of the new seed of life after a rain very heavy to carry. Scholar is the rule rather than the flood sometime in the second millennium BC and 3, and some 4 to 5,000 years ago. This was about the time that the Egyptians first domesticated cats. They did get on board? And as you hear the rats and mice? The cats were guardians of the grocery stores in the ark, which was always hanging on to dry land again in the foot? EWhat are the koala is the ship if it is limited to the continent of Australia? Really do better than the 5000 years, much has to raise questions.

The equalizer is great in every debate time. Time changes everything, including the diameter species. As people all over the world, change their skin color, eating habits adapted to new environments, the clashes have occurred with others in the migration of valuable land that was affordable life support resources, ieabundant prey for hunters and gatherers, then domestic farm animals and food / cereal crops for food.

Survival is unforgiving of failure. Both are survivors ... or not. This is a defining characteristic of "life" which yearns to survive. Another feature is that the survival of individual members of a species that not only or so for a limited time. A life as we call it. Only large groups or classifications of rocks, trees and other living things, includingthat each species may survive indefinitely, if it happened.

The fossil record is very incomplete evolution of the cat. There is evidence, tracing the cat at about 200 million years, evolving with the cat begins when it apart from reptiles. From this point on, scientists from the family of cats into two main groups. Cat cats feline, which contains all species of modern cats and saber-tooth, all of which are extinct. The 'Felidae family' or felinecollected in three Genre:

Panthera - lions and tigers and ... Panther, or cats that roar. Felis - lynx, ocelots, and other small your cat Fluffy. Acinonyx - or the cheetah. You are in a group of them because they can not move their claws like other cats.

Originally diagrams developing cat cats divided into two main categories: Big Cats and kittens. The award was presented by the size and shape of their skulls. But, it was discovered that the division is notviable, because studies including a gradual transition of the skull showed properties from the smallest to the largest cats. There was essentially no separate supply with these criteria.

Recently, DNA studies have provided insights cat available for development, as it migrated from Asia to North America via the Bering Sea land bridge that about 9 million years ago, has appeared. These predators such as panthers have been appeared in Asia about 2 million years before the land bridge was exposed by the fallSea level. Cats are considered, along with people who are successful hunters. They would then loot the migration and simply survive the challenges of roaming vast areas in which to explore new environments. (To think that a cat sniff unexplored bush, or strange new object, either inside or outside their territory) as a result of the cat returned several American lines recently developed in Asia over the bridge and with each migration, evolutionary forces in these cats rainbowTypes of lions and leopards, lynx, ocelots and domestic cats home today. Where people were at this moment? Well, no, to find out where ... again. Anatomically modern humans in Africa developed exclusively that between 100,000 and 200,000 years, according to most experts, with inferences on the data of mitochondrial DNA. Obviously the cat is long evolutionary history with the existing in this world.

It was about 10,000 years ago, when the people stopped, hunters and gatherers, and began to cultivatethe country that the relationship between humans and cats began seeds. Until then, the cats lived many parts of the world except the arctic, Antarctica, Australia and inhospitable. As the first modern humans emigrated from Africa to Europe and Central Asia, would not cross to the cat and the human way was impossible. But it was when people began to cultivate plants that certain types of cats and humans co-workers have started a relationship interesting, if notTorsion fatal cat in evolution.

Find the beginning of the peasants that the newly developed food storage, grain storage is mainly an attraction for small rodents such as rats and mice. Archaeological evidence supports this if that ruins discovered preponderance of rodents in storage storage skeletons were buried relics. One can easily suspect that the smaller cats carry their prey, could not resist the farm and will probably be the concentration of mice and rats feastsilos offered so early. Human beings, is an intelligent creature would also dislike, rodents, and cats had (have) have noticed each other. An early farmers could be a litter of kittens and took home to try to keep it in order to protect his hard work in the fields.

Most likely would be the first kittens have retained much of their wild nature and maintained a distance "security" from their human benefactors. But, as generations of boys hadtreated more contact with people, especially by the people as a kitten, which would have grown tolerant and interactions accessible to people with cat, maybe even sleeping in their homes. Speculate in this way could the early stages of domestication began. Two types of cats have been more successful in adapting to this new relationship, and Felis silvestris, Felis lybica. Silvestris was more adaptable to the environment and of climate, while lybica preferably in Middle EastEast.

Early Egyptians had several gods, and these were attributed to the animalistic quality. The chief god of Egypt was the sun god Ra, symbolized by a lion. Ra was said, the world during the day seems like a chariot race in the sky, from sunrise to sunset rule. On the night he fell into the darkness where he was vulnerable to his enemies. But with the qualities of a lion who had a vision of a cat that you could see in the dark, to better protect themselves. Bast was known asGoddess of fertility, birth and family, which was symbolized by a cat. And do not escape from the Egyptians, how strong the maternal instinct in cats, when they care for their puppies. Cats were buried with the Pharaohs and even cemeteries were just for ordinary people, the cats at their own tune.

It 'been following the rise of the Roman Empire, that cats make their way to Europe as a pet. Cats have lost their status as "god" and assumed the role more practical,a 'pet'. Until then, the cat-mouse-human triangle was fairly well defined, and how people migrated to grow as the world is gone, the cat and mouse went right next to them. Domestic cats traveled the spice routes to Asia and America the seas. Wherever they went, the cat populations have established only through intersections among their peers, but for the breeding of native species, they met on the road. The result is a plethora of colors, hair, hairLength and model, to identify the cats today.

The effects of domestication on the development of cat can be summarized as follows:

The tendering period (before 7000 BC), of feral cats in competition with humans, hunter-gatherers for birds and small mammals. Commensal Period (7000-4000 BC), of "semi-domestic" cats eat insects in the villages around and dominated early. Early period of domestication (4,000 to 3,000 BC), with the confinement of catsCult status Full domestication period (3000 BC - present) keep the disclosure of the cat and the proliferation of cats from Egypt *

All of this experience, that cats and humans, when the crop began to formulate and we began to be settled by humans as our hunter-gatherer migrations, when a chance encounter can be designed. Our early ancestors of Agriculture would have many problems, solutions that solve it for granted today. But the cat did not forget their contributionto our success and this could also explain the apparently proud of their nature. After all, networking is everything in this world, surpassed only by human arrogance, as an idea, through faith in our intellectual superiority, will only perpetuate the belief in our disconnection from the natural to dismiss. Fortunately, only humans are capable of as a marble. Cats have never forgotten their roots. Deep roots in the evolution of cat domestication and time.

There areMoments where I am, like many others I suspect, lost in the loneliness that results in the recognition of the separation to be, or the distance that seems to be in this life between us. And 'then I just watch the sky, amazed at the distance between me and the furnaces of hell, the stars are available. Even then a great distance, the bin in the time that the light is measured in years, I am comforted in knowing that we are all fromsame stuff that light spillage from those factories. We are so connected ... but it is blind for granted as we pursue our business every day life inflated. Returning to this place is my kitten in my lap and I stroked her back while she quietly accepted the affection. It does not take much to change our roles, and sat down at their place, even in the back and enjoyed the surprise attack on it. And with a little 'fantasy, I'm following the path of the catEvolution in my head.
