Perhaps the most poignant example of an "extra-quality" relationship is the formation of long-term, non-reproductive friendships and the expression of grief at their loss. In the savannas of Africa, elephants are the quintessential case study. They live in matriarchal herds, but their social bonds are not merely hierarchical. Researchers have observed elephants engaging in what can only be called greeting ceremonies—flapping ears, clicking tusks, and intertwining trunks—with specific individuals they have not seen for extended periods, a behavior that implies episodic memory and emotional recognition. When a herd member dies, elephants exhibit behaviors that transcend simple distress. They will stand vigil over the body, touching the bones and tusks with their trunks, and have been known to revisit the site of a death years later. This is not a utilitarian act; it does not aid in foraging or predator avoidance. It is a ritualistic acknowledgment of loss, a phenomenon once considered the exclusive province of human grief.

Another remarkable example of altruism is found in the animal kingdom's most iconic example of cooperation: the African elephant. When an elderly or injured elephant becomes too weak to walk, its herd will often work together to support it, using their trunks and tusks to lift and push the struggling individual. This selfless behavior not only demonstrates empathy but also highlights the importance of social bonds within the herd.

High-quality social relationships are favored by evolution because they directly improve an individual’s chances of reproducing and protecting offspring. Case Studies:

If survival is the work of the animal world, then play and grooming are the "social currency" that buys stability. These activities are essential for maintaining extra quality relationships.
