Article about why are animals important to us
Answers
Answer:
Animals are our companions, our workers, our eyes and ears, and our food. They appear in ancient cave paintings, and on modern commercial farms. We have domesticated some of them, while others remain wild and are sometimes endangered by our activities. They keep us company, and while they can provide comic relief, they also serve us as valuable assistants.Researchers at the University of Chicago estimate that the domestication of dogs took place from 11,000 to 16,000 years ago. Genetic evidence indicates that wolves suffered a significant reduction in population after dogs diverged from them, so the wolf gene pool that gave rise to dogs was much more diverse then than it is now. Genetic research on generations of foxes in Russia over more than 50 years suggests that selection for tame behavior also brings about traits like color variation and breeding outside of the natural yearly cycle, which raises the value of the animals to humans.
