介绍： This is Scientific American's 60-second Science, I'm Christopher Intagliata.
Go snorkeling in a lot of places, you'll find coral. But on Israel's Mediterranean coast?
"I think it's the only place in the world that you can find whole prehistoric villages submerged under the sea."
Ehud Galili is an underwater archaeologist at the University of Haifa. He says one submerged village, called Tel Hreiz, sits 5 to 10 feet under the water. The community was populated some 7,000 years ago.
There, the archaeologists have found pottery and flint, human skeletons, the remains of deer, cows, pigs and dogs, and hundreds of olive pits—probably the remains of olive oil production. And the researchers also found a 300-foot long stretch of huge boulders—a wall.
After ruling out other possible uses for the wall—like defense against enemies or corralling animals—the scientists determined that the formation was actually an ancient seawall, the oldest known example in the world. The results are in the journal PLOS ONE.

如果你经常去潜水，你会发现很多地方都有珊瑚。但以色列的地中海沿岸有吗？
“我认为这是世界上唯一一处可以发现沉入海底的整个史前村庄的地方。”
海法大学的水下考古学家埃胡德·加利利说到。他表示，一个叫作“泰尔赫雷兹”的水下村庄坐落在距离海面5到10英尺处。这个村庄大约在7000年前开始有人居住。
考古学家在那里发现了陶器和燧石、人类骨骼、鹿、牛、猪和狗的遗骸，还有数百个橄榄坑，这可能是橄榄油生产地遗址。研究人员还发现了一段300英尺长的巨石墙。
在排除了这座墙用于防御敌人或圈养动物等其他可能用途后，科学家判定该结构实际上是古代防波堤，是全世界已知最古老的范例。研究结果发表在《公共科学图书馆·综合》期刊上。
