The wilderness might appear to be a cold and unfeeling place, distinct from the world where we live. But even amid the densest, most foreign-seeming jungle, there's something familiar to be found within the creatures who inhabit it - hearts not unlike our own.
And as these stirring images show, those hearts can break.
Photographs taken in China's Qin Ling Mountains tell the tragic story of a mother golden snub-nosed monkey who had just lost her child, and how she grieved the loss.
The baby monkey, who was just a year old, had been killed after falling from a tree while gathering food. Soon after, as People's Daily reports, his mother raced to where his lifeless body lay on a rock, "screaming as if she was calling her baby not to leave her."
She could not revive him, but the mother did not relent. Instead, she scooped the baby's body into her arms, continuing to keep it close as if unable to accept her baby's sudden passing.
Emotional processes, like mourning, may be difficult to measure in other animals, but outward signs of bereavement suggest they experience such tragedies much in the same way we do.
"There is no doubt that many animals experience rich and deep emotions," writes animal behaviorist Dr. Mark Bekoff in Psychology Today. "It's not a matter of if emotions have evolved in animals but why they have evolved as they have. We must never forget that our emotions are the gifts of our ancestors, our animal kin. We have feelings and so do other animals. Among the different emotions that animals display clearly and unambiguously is grief."
