Human-Dolphin Partnership Reserve
ahbe writes that the Myanmar government recently established a protected reserve for partnering between fisherman and wild dolphins. From the article: "The fascinating partnership involves fishermen summoning the dolphins to voluntarily herd schools of fish toward the boats and awaiting nets. With the aid of the river-dwelling dolphins, the fishermen can increase the size of their catches by threefold, and the dolphins appear to benefit by more easily preying on the cornered fish in both nets and on the muddy banks of the river."
And thanks for all the fish.
Dolphins are pretty smart, all right. They have excellent social intelligence, even to the point of being able to communicate somewhat effectively with other species, most notably us humans.
I've always found it relatively obvious why dolphins wouldn't develop very high intelligence as corresponds to that measured by IQ, which is generally called g. We humans evolved heightened intelligence because that's what we needed to be able to adapt to rapidly changing conditions and to exploit multiple sources of food. But why would dolphins really develop both the sort of intelligence, and the limbs, needed to make and handle tools (which I think is an important part of developing the g type of intelligence as that which is seen in humans)? Their only natural predators are sharks and orcas, and they've got those pretty well covered due to their excellent teamwork skills. Those lucky bastards are practically living in paradise!
But then again, maybe we'd find that dolphins have the neccessary intelligence for toolmaking, if we just gave them some manipulators. That is to say hands.
