The lecturer argues that the origin of domesticated dog is not yet clearly proved. This contradicts the reading passage's claim that it is understood how, when, and where dogs became domesticated.
First, the lecturer contends that wolves might have not available to assist with hunters. As wolves chase preys when they hunt, it could have disturbed ancestors' method of hunting which was to set up traps and to hide until animals got caught. Also, it would have been very hard to train wolves because they became aggressive as they age. This counters the reading passage's claim that dogs evolved from wolves that were tamed by ancestors as hunting helpers.
Next, the lecturer maintains that the approximate period that dogs were domesticated is much earlier than the year of 16,000. For instance, archaeologists have found footprints in a cave of ancient time. The footprints involves a trace of boy along with dog. According to researchers, it is formed more than sixteen thousand years ago. This refutes the reading passage's claim that scientist have revealed that dogs were domesticated about 16,000 years ago.
Last, the lecturer asserts that dogs were not primarily domesticated in China and spread to other continents. Given genetic information provided by recent research, the origin of dogs is not only found in China, but also Europe, North America and Middle East, which indicates they came from distinctive origins of different places. This contradicts the reading passage's claim that dog were firstly domesticated in China and, after that, distributed to different locations around the world. |
