今日のテキスト ROCK ART MAY BE WORLD'S OLDEST

Archeologists in Indonesia have re-examined an old find and are making a new conclusion. They say prehistoric cave drawings on the island of Sulawesi may be the oldest in the world.
The first stencils of hands and drawings of animals were discovered in the 1950s. Up until now, scientists believed the cave art was no older than 10,000 years. The team of archeologists from Indonesia and Australia measured dates of minerals covering the surfaces of drawings in seven caves. They've calculated the age of some of them to be at least 39,900 years old. They say it could predate cave drawings in Spain, thought to be the world's oldest.
The new findings have been published in the British journal Nature. Scientists around the world are paying close attention as the study could change the common belief that cave drawings originated in Europe.
