Step-by-step explanation:
The answer to your question is option E: a broader spectrum of animals, as opposed to specializing in the hunting of a few species.
During the broad-spectrum revolution, humans shifted their attention to a broader range of animals, rather than focusing on hunting a few specific species. This shift in hunting strategies allowed humans to adapt to new environments and ensure their survival. They began gathering different types of plants and hunting different types of animals that they came into contact with, including fish, animals that reproduce quickly, and small-bodied animals.
For example, in the Paleolithic Age, human populations relied on subsistence hunting and gathering for survival. They ate a variety of foods such as nuts, fruits, berries, wild grains, honey, fish, birds, shellfish, insects, and other animals. Their diet depended on the environments in which they lived. In lush, warm environments, they had access to a greater variety of edible plants and animals. In colder environments, they relied more on animals and fish.
