edit to the above;

seeing how a person must be delusional not to understand that humans are oviously a type of animal....(a part of nature).......the answer is: Humans and Elephants- this is if the question relates to crying due to emotional pain such as sorrow for another 1 having died or being away from.... i hope this helped
