How is it that animals can prove to be kinder and much less selfish than human beings?

Animals often display kindness and altruism in ways that can exceed human behavior, particularly in social species. This may stem from evolutionary advantages, where cooperative behavior enhances survival and strengthens group bonds. Additionally, many animals exhibit empathy and nurturing behaviors, suggesting that kindness is a fundamental aspect of their social structures. In contrast, human complexities, such as competition and societal pressures, can sometimes overshadow these innate tendencies.
