哥伦布到达了美洲,一个新大陆被发现了……不对,美洲最初的发现者才不是航海家呢,他们是印第安人。大多数科学家认为印第安人的祖先来自亚洲。大约5万年前,经过一系列地壳运动,海水被大量蒸发,一些海底山脊露出了海面,形成了天然的桥梁,一些不甘寂寞的亚洲人走上了这些“桥”。这些“旅行家们”经过长途跋涉,进入了美洲,被后人称为“印第安人”。 Columbus reached the Americas, a new continent was discovered ... No, America’s first discoverer was not a navigator, they were Indians. Most scientists think Native Americans come from Asia. About 50,000 years ago, after a series of crustal movements, the sea water was greatly evaporated. Some submarine ridges exposed the sea surface and formed a natural bridge. Some unwilling Asians embarked on these “bridges.” These “travelers” traveled long distances to enter the Americas and be called “Indians” by their descendants.
