So, I'm a bit bored at work and came to think about our beloved animal friends and their alleged ability to mourn.
Most of us have heard about or seen elephants going on a detour so they can pass by carcasses of dead members of the group, picking up their bones and acting in a manner that resembles what we humans would describe as mourning. Same goes for pets who have lost a long-time friend/mate etc etc.
What do you guys think, can animals mourn the loss of a family member/group member? If so, does this apply to all animals or just a chosen few, and do you believe that the feelings are similar to what humans have and would that categorize them as sentient beings?
