In Yellowstone National Park, gray wolves have been recorded risking injury and death to help pack mates escape during aggressive attacks by neighboring packs. Why would any wild animal take such a risk? This ability to relate to another’s pain and distress, to feel empathy, is rarely attributed to any creature except for modern humans. While we cannot know the details of the lives of past Homo sapiens such as hunter-gatherers, we can look to gray wolves and think about just how much we had – hopefully still have – in common.
