The TV show "60 Minutes" ran a segment that tells us something important about fatherlessness.

The park rangers at a South African wildlife preserve were concerned about the slaughter of 39 rare white rhinos in their park. It turned out that the rhinos were killed not by poachers but rather by juvenile delinquents—teen elephants.

The story began a decade ago when the park could no longer sustain the increasing population of elephants. They decided to kill many of the adult elephants whose young were old enough to survive without them. And so, the young elephants grew up fatherless.

As time went on, many of these young elephants roamed together in gangs and began to do things elephants normally don't do. They threw sticks and water at rhinos and acted like neighborhood bullies. Without dominant males, the young bulls became sexually active, producing excessive testosterone and exhibiting aggressive behavior. A few young males grew especially violent, knocking down rhinos and stepping or kneeling on them, crushing the life out of them. Mafuto the gang leader eventually had to be killed.

The park rangers theorized that these young teen-aged elephants were acting badly because they lacked role models. The solution was to bring in a large male to lead them and to counteract their bully behaviors. Soon the new male established dominance and put the young bulls in their places. The killing stopped. The young males were mentored—and saved.
