New Clues About Dog Domestication | |
Dog's tooth leads to discovery of earliest known journey in UK history Dogs may have been domesticated more than once The Big Search to Find Out Where Dogs Come From A Soviet scientist created the only tame foxes in the world The Learning Network: 12 Years of Lesson Plans about the Animal Kingdom NOVA: Dogs and More Dogs British Archaeologists recently discovered a 7,000 year old dog tooth just one mile from Stonehenge. This week, researchers at Durham University announced that upon examining the tooth's enamel, they concluded that the dog hailed from Vale of York - meaning that the dog had made a 250 mile journey. This discovery indicates that not only was Stonehenge a destination of import before the construction of the standing stone circle, but also clarifies that hunter-gatherers in modern day Britain were using domesticated dogs as early as 5,000 BCE. This exciting new evidence adds to our growing knowledge of dog domestication around the world. In June, a group of scientists at the University of Oxford published a study suggesting that dogs may have been domesticated from grey wolves twice - once in East Asia and once in Europe. This study was the result of a massive project, headed by Dr. Greger Larson at the University of Oxford Archeology Department, that collected and analyzed about 1,500 dog bone samples and photographs from around the world. While the full story behind dog domestication continues to be contested, we may learn new clues as scientists continue to analyze this impressive collection of samples. [MMB] The first link takes readers to an article from The Guardian earlier this week that details the dog tooth discovery near Stonehenge and its significance. Next, readers will find a June 2016 summary of the University of Oxford Study, published in Science, that suggested a dual domestication of dogs. (Readers interested in reading the original study in full may find a link to the full study through this summary). The third article is a January 2016 New York Times overview of Dr. Larson's research project. Moving along, Lucy Jones of the BBC wrote a fascinating article about how Soviet scientist Dmitri K. Belyaev led a project to domesticate the fox in order to study the nature of domestication. Moving along, instructors may want to check out the New York Times Learning Network's 2010 collection of twelve lesson plans about animals, which includes a lesson on domestication. Finally, NOVA's Dogs and More Dogs page features a number of interactives that may be of use in the classroom, including Dogs Around the World. |
