A lower jaw bone was found in Dmanisi, Georgia, it belonged to a member of the homo-erectus family, the human's extinct cousins. He was a male of about 40 years old, who lived probably 2 million years ago. The jaw is missing all its teeth except for one.
Researchers, led by Georgian National Museum anthropologist David Lordkipanidze, had determined that he lived a long time like that, which means someone was helping him to eat.
Two million years ago, someone was feeding him. Someone cared about him, maybe someone loved him, back in deep time even before the current human species began—a person or a group was practicing compassion. Someone was being kind for the sake of being kind.
