Wolves, Dogs And Humans
Answers
Question number | Answer | Keywords | Location of keywords |
---|---|---|---|
1 | NO | all dog breeds had only one ancestor, the wolf. They did this by analysing the genetic history through the DINA of 162 wolves from around the world and 140 domestic dogs representing 67 breed.
& The fact that our companionship with dogs now appears to go back at least 100,000 years |
Paragraph A;
Line 4 & Line 6 |
2 | NO | The research also confirms, for the first time, that dogs are descended only from wolves and do not share DNA with coyotes or jackals. | Paragraph A;
Line 4 |
3 | NOT GIVEN | – | – |
4 | YES | Wolves may have started living at the edge of human settlements as scavengers, eating scraps of food and waste. Some learned to live with human beings in a mutually helpful way and gradually evolved into dogs. | Paragraph B;
Lines 2 – 3 |
5 | YES | In return for companionship and food, the early ancestor of the dog assisted humans in tracking, hunting, guarding and a variety of other activities. | Paragraph C;
Line 1 |
6 | D | The wolves that evolved into dogs have been enormously successful in evolutionary terms. They are found everywhere in the inhabited world, hundreds of millions of them. | Paragraph B;
Lines 5 – 6 |
7 | B | early humans came to rely on dogs’ keen ability to hear, smell and see – allowing certain areas of the human brain to shrink in size relative to oilier areas. | Paragraph D;
Line 1 |
8 | A | Dr. Groves believes this reduction may have taken place as the relationship between humans and dogs intensified. The close interaction between the two species allowed for the diminishing of certain human brain functions like smell and hearing. | Paragraph E;
Last line |
9 | Selectively breed | Eventually humans began to selectively breed these animals for specific traits. | Paragraph C;
Line 2 |
10 | C | Dr. Groves repealed an assertion made as early as 1914 that humans have some of the same physical characteristics as domesticated animals, the most notable being decreased brain size. The horse experienced a 16 percent reduction in brain size after domestication while pigs’ brains shrank by as much as 34 percent. | Paragraph E;
Lines 1 – 2 |
11 | B | Wolves may have started living at the edge of human settlements as scavengers, eating scraps of food and waste. Some learned to live with human beings in a mutually helpful way and gradually evolved into dogs. | Paragraph B;
Lines 1 – 2 |
12 | A | The conventional view is that the domestication of wolves began between 10,000 and 20,000 years ago. However, a recent ground-breaking paper by a group of international geneticists has pushed this date back by a factor of 10. | Paragraph A;
Lines 2 – 3 |
13 | C | Dogs acted as human’s alarm systems, trackers and hunting aids, garbage disposal facilities, hot-water bottles and children’s guardians and playmates. Humans provided dogs with food and security. This symbiotic relationship was stable for over 100,000 years and intensified into mutual domestication,’ said Dr. Groves. | Paragraph D;
Lines 3 – 5 |
14 | A | The research also confirms, for the first time, that dogs are descended only from wolves and do not share DNA with coyotes or jackals. The fact that our companionship with dogs now appears to go back at least 100,000 years | Paragraph A;
Lines 5 – 6 |
