The Evolution Of Dogs
Dogs have Evolved and change a lot over time to form the dogs we know today. What most of us know is that dogs have evolved from wolves, yet the evolution of dogs has gone deeper than this. According to www.Britannica.com/dogs, the first dog like animal was called the
This animal is the forebear of the cat, wolf, jackal, raccoon, Hyena, and bear.Then, an animal evolved that was in very cloe resemblance to the dogs we know. . Finally, dogs, wolves, and jackals we know today evolved and are members of the
The Origin Of Dogs
Researchers have been studying the origin of dogs for years. According to research studies, dogs originated from Europe about 19,000 to 32,000 years ago. "Early dog fossils have been found from Europe and were compared to the genetic samples of wolves that lived in America.", said the author of the article "Where Were Dogs Domesticated." The genes had very close resemblance. Therefore, there is a chance that dogs came from Europe. Also, according to the article "Where Do Dogs Come From?DNA Studies says it's from the Middle East" dogs come from the middle east. Both the article and the research studies that I've read conclude to the fact that dogs origin from somewhere around Europe and Asia.
The Body Structure of a Dog
The 2 basic head shapes dogs are a narrow skull with a long face or a wide skull with a short face. There are also 42 teeth altogether in a dog's mouth.
There are 27 bones in the spine. This includes all the bones from the tip end of the tail to the beginning of the head. Also, There are 13 ribs. The type of hair on a dog can vary depending on the breed or type of mutt the dog is.
Dogs have five toes on their feet. There is a claw on the end of each toe. On the bottom of the foot has ruff pads to protect the foot from sharp objects on the ground. The legs include the hind limbs, thigh bones, stifle, which is the upper portions that are linked with the femur, and lastly, the hock, lower portions that link with the hind limbs.
Why Did Humans Domesticate Dogs?
Humans domesticated dogs because dogs could serve as a purpose for them. They soon were able to farm and hunt easier. Some time in the past humans made compatible friends with the dogs of the wild.
Different purposes for different dogs
Sporting dogs are good for hunting animals. Different dogs hunt different animals. For instance, terriers are mostly used for hunting small animals like rats, mice, voles, moles, etc. On the other hand hounds are good for hunting fox, rabbits, etc.
Work dogs are meant for working on farms and other areas. For example, a sheep dog is good for pulling sheep(hence the name sheep dog)
Today many families just have dogs as pets or companions.
I chose dogs as my topic for my prezi because I have always loved them since I was little. I picked my resources by looking for reliable sites that would not only help me with my research, but also be easy to get to. During the time I used prezi I met some compromisable dislikes about the program. for example, even though there were a lot of backgrounds to chose from I would have liked to make my own. Overall, I really enjoyed prezi and liked the presenting system. I learned a lot of new things about dogs during this project. I didn't know where and how dogs came to be. That's when I researched the evolution and originality of dogs.
