Dog Evolution Reading Levels

Read each passage, then answer the questions that follow. The questions become more challenging as you move through the levels.

Level 1: Getting Started

Read the short passage and look for its main idea and the order of events.

Long ago, some wolves began visiting the edges of human camps. They searched for scraps left behind after meals. Wolves that were calmer around people could find food more easily. People also found these calmer animals easier to live near. Over many generations, some wolves changed. They became more suited to living with people. In time, their descendants became the dogs we know today.

1.What is the main idea of “A Long Friendship”?

How wolves hunt in the forest
How some wolves gradually became dogs
Why people built camps near wolves

2.Put these events in the order they happened. Write 1 for first, 2 for next, and 3 for last: calmer wolves lived more easily near people; some wolves searched for camp scraps; the descendants of these wolves became dogs.

Level 2: Building Understanding

Read the explanation and identify how the process unfolded.

Domestic dogs are descended from ancient wolf populations. The change took place over a very long time, not within a single wolf’s lifetime. Some wolves found food near human camps. Those that were less wary of people may have stayed close to this reliable food source. People, in turn, may have tolerated or encouraged the calmer wolves. Over many generations, animals that could live successfully alongside people became more common in these groups. Their bodies and behaviour gradually differed from those of their wild relatives. Later, people bred dogs for particular tasks and traits, such as helping with herding or guarding. This long relationship produced the many kinds of dogs living with people today.

3.What is the main purpose of “How Wolves Became Domestic Dogs”?

To explain a gradual change from wolf ancestors to domestic dogs
To persuade readers that dogs should be used for herding
To compare the best-known dog breeds

4.Describe three stages in the process explained in the passage, beginning with wolves near camps and ending with dogs bred for particular traits.

Level 3: Extending Your Reading

Read the more detailed explanation. Consider its audience, language and structure.

Dogs and wolves belong to the same biological family, but domestic dogs did not appear suddenly. Their history developed through a lengthy relationship between people and ancient wolf populations. Wolves that approached human camps could take advantage of discarded food. Individuals that were more tolerant of people were more likely to remain nearby, while people could benefit from having animals close to their settlements. Across many generations, this relationship influenced which animals survived and reproduced near people. This process is known as domestication. As dogs became established in human communities, people also began favouring animals with useful behaviours and features. Selection for different roles helped produce a wide range of dog shapes, sizes and abilities. The history of dogs is therefore not a simple story of people changing wolves at once. It involves gradual changes across generations, as well as interactions that affected both animals and humans. Scientists continue to investigate when and where different stages of this shared history took place.

5.Who is the likely audience for “A Shared Evolutionary Path”? Give one piece of evidence from its vocabulary or explanations to support your answer.

6.Explain how the passage organises its account of dog domestication. Identify two words or phrases that guide the reader through the explanation and describe what each one signals.
