問題詳情
From the goose that laid the golden egg to the race between the tortoise and the hare,Aesop's fables are known for teaching moral lessons rather than literally being true. Buta new study says one such tale might really have happened. It's the fable about a thirstycrow. The bird comes across a pitcher with the water level too low for him to reach.The crow raises the water level by dropping stones into the pitcher. Now, scientistsreport that some relatives of crows called rooks used the same stone-dropping strategy toget at a floating worm.Christopher Bird of Cambridge University and a colleague exposed the rooks to a6-inch-tall clear plastic tube containing water, with a worm on its surface. The birds usedthe stone-dropping trick spontaneously and appeared to estimate how many stones theywould need. They learned quickly that larger stones work better.In another paper, Alex Taylor and Russell Gray of the University of Auckland in NewZealand pointed out that in an earlier experiment, the same birds had dropped a singlestone into a tube to get food released at the bottom. So maybe they were just followingthat strategy again when they saw the tube in the new experiment, the scientists suggested.But Bird's paper argued there's more to it: The rooks dropped multiple stones rather thanjust one before reaching for the worm, and they reached for it at the top of the tube insteadof checking the bottom. The researchers also said Aesop's crow might have actually beena rook, since both kinds of birds were called crows in the past.
