The beginning of the domestication of animals as per the excavated evidences goes back to:

Lower Palaeolithic period
Middle Palaeolithic period
Upper Palaeolithic period
Mesolithic period

The correct answer is (c), Upper Palaeolithic period.

The Upper Palaeolithic period is the last part of the Paleolithic or Old Stone Age. It lasted from about 40,000 to 10,000 years ago. During this time, humans began to domesticate animals. The first animals to be domesticated were probably dogs, followed by sheep, goats, and cattle.

There are several reasons why humans began to domesticate animals. One reason is that domesticated animals provide a source of food. Animals can be hunted for their meat, and their milk, eggs, and wool can be used for food and clothing. Domesticated animals can also be used for labor. They can be used to pull plows, carry loads, and transport people.

The domestication of animals had a profound impact on human society. It allowed humans to live in larger groups and to produce more food. This led to the development of agriculture and the rise of civilizations.

The other options are incorrect because they are not periods of time when humans began to domesticate animals. The Lower Palaeolithic period lasted from about 2.5 million to 200,000 years ago. The Middle Palaeolithic period lasted from about 200,000 to 40,000 years ago. The Mesolithic period lasted from about 10,000 to 5,000 years ago.
