But 65 percent of those signs stayed in use during that entire time period -- things like lines, rectangles triangles, ovals and circles like we see here from the end of the Ice Age, at a 10,000-year-old site high in the Pyrenees Mountains.
但是，65%的符号被一直沿用， 比如直线、长方形、三角形、椭圆形和圆形， 就像我们在比利牛斯山脉 这个有一万年历史的冰川后期遗迹中所看到的。
