100 Years of Breed “Improvement”

100 Years of Breed “Improvement”
For the sake of honest disclosure, I will admit to owning “purebreds” (the ‘pureness’ of purebreeds is a discussion for another time) but I also have mutts. All the dogs I’ve had since childhood had a few things in common, they were friendly, prey driven, ball-crazy, intense, motivated, athletic (crazy dogs are easier to train) and none had intentionally bred defects. I would never buy/adopt a dog whose breed characteristics exacted a health burden.(Asher 2009). That just incentivizes people to breed more of these intentionally unhealthy animals. The dogs on the left are from the 1915 book, ‘Breeds of All Nations‘ by W.E. It seems incredible that at one time the Bull Terrier was a handsome, athletic dog. The Basset Hound has gotten lower, has suffered changes to its rear leg structure, has excessive skin, vertebra problems, droopy eyes prone to entropion and ectropion and excessively large ears. A shorter face means a host of problems. Once a noble working dog, the modern St. Like this:

How has the amazing diversity of plants and animals evolved? Birthplace of Dogs Discovered The time-tested bond between humans and dogs is well-documented, but researchers have puzzled for a long time over where and when our species became so interlocked. Previous studies indicated East Asia as the site where wolves were first tamed, but a new study delves even deeper and reveals even more history of man's best friend. From Science Daily, These discoveries are presented in an article in the scientific journal Molecular Biology and Evolution, where it is claimed that the dog appeared 16,000 years ago, in Asia, south of the Yangtze River in China. This is a considerably more specific date and birthplace than had previously been put forward.

The Wicker Man (1973 Edit Storyline Sgt. Howie travels to Summerisle to investigate the disappearance of a young girl. How Dogs Know What You're Feeling When you hear a friend’s voice, you immediately picture her, even if you can’t see her. And from the tone of her speech, you quickly gauge if she’s happy or sad. You can do all of this because your human brain has a “voice area.” Now, scientists using brain scanners and a crew of eager dogs have discovered that dog brains, too, have dedicated voice areas. The finding helps explain how canines can be so attuned to their owners’ feelings. “It’s absolutely brilliant, groundbreaking research,” says Pascal Belin, a neuroscientist at the University of Glasgow in the United Kingdom, who was part of the team that identified the voice areas in the human brain in 2000.

The Anatomy of the Dog Soft Palate. I. Histological Evaluation of the Caudal Soft Palate in Mesaticephalic Breeds - Arrighi - 2011 - The Anatomical Record: Advances in Integrative Anatomy and Evolutionary Biology Abstract The gross anatomy and overall structure of the soft palate has been described in the average dog's head, however, no descriptive microanatomical studies of the dog soft palate are available, despite their possible utility in view of the manifold and important repercussions of this organ physiology. This is the first of two companion papers, dealing with the caudal part of the soft palate in the canine species, in mesaticephalic and brachycephalic dogs.

BioInteractive Search Results Lectures How reasoning and evidence are used to understand human evolution. Genetic evidence shows that humans evolved in Africa and continue to evolve. Stone tools are well-preserved evidence of past human activity. The hominid fossil record of the past six million years gives us surprising insights into the path of human evolution. DNA Backs Lore on Pre-Columbian Dogs John W. Adkisson for The New York Times Peony, a Carolina dog. Some of the breed’s rare traits include a fishhook tail, a pointed, somewhat lupine face and the habit of digging snout pits. These are Carolina dogs, and though they are friendly, one can instantly sense they are different from other dogs. Several rush to the gate, their whole bodies wagging eagerly.
