Do Animals Know They're Old?

Do animals know they are old. Why does an old male lion in the Serengeti walk away from his pride and sit alone on a ridge until his body gives out. Why do old wolves in Yellowstone start falling behind on the trail and then peel off into the snow. What did Jane Goodall see when the old chimpanzee Flo stopped traveling with the group in her final year at Gombe in Tanzania. Why does an old elephant matriarch like Echo of Amboseli head back to the same swamp where her grandmother died. And what does the science of mirror self-recognition, elephant cognition, macaque metacognition, and the recent cleaner wrasse work tell us about whether an aging animal can actually know that its own body has changed. Four real animals, two pieces of hard science, one honest answer, no fluff. 📚 SOURCES & FURTHER READING George B.
