This is the story about a dragon . Well it's not really about a dragon, but now that I have your attention...

 It's really a story about monkeys; some of them lived on an island, some of them lived on the mainland.

One day, a monkey on the island got tired of always having to climb down the tree and go to the stream to get a drink of water. So, this monkey broke a coconut in half, making a couple of bowls. Then the monkey took one of the bowls, filled it with water, brought it up the tree, and sat on a branch, sipping the water.

Another monkey watched the whole thing. This monkey climbed down its tree, picked up the other half of the coconut, and did the same thing.

Eventually, other monkeys on the island did the same thing as the first two monkeys.

The strange thing is, not soon after the first monkey on the island thought of this idea, monkeys on the mainland started doing it, too. Now how did they know to try the same idea? Did a seagull fly from the island to the mainland and tell a monkey? Did a monkey swim, or raft, to the mainland to tell them?

Or, was it an original idea that both monkey groups came up with at about the same time, independently. What do you think? Which would you like to believe?

Which answer would you choose: I. island creatures went to the mainland and brought the knowledge with them;

II. the original idea was thought up by the mainland creatures without any help from  the island.
