In nature, animals have shown remarkable characteristics that seem very human-like. Whether it is the bond between a mother and her child, or that of friends, they are just as human as us. There have been several studies researching animals and their emotions. For example, a study published in 2010 discussed how consolation, or providing comfort to another individual to make them feel better, has been used to demonstrate empathy in human children.
