When a dolphin became trapped in a marina lock in the 1980s, she was rescued and cared for at a dolphin sanctuary in Australia, where she must have picked up a few tricks from the other dolphins. Nearly 20 years later, marine biologists spotted several wild dolphins near Australia performing a trick known as tail walking-rising out of the water to a vertical position and gliding backward for several feet powered by flecks of the tail. Tail walking is a cool trick for trained performing dolphins, but it serves no known purpose in the wild. The biologists concluded that the rescued dolphin learned the skill during her time in the sanctuary and taught it to her pod mates when she was returned to the wild.
At times we are much like the dolphin. We are taught and then move forward to teach other people what we know. We hand down knowledge from generation to generation – at least that’s the way it should be in my opinion.
