最近,科学家们宣布他们成功地从一具死于6万年前的古人化石中提取到了DNA,这名在解剖学上与现代人相同的古人类发现于澳大利亚的一个湖畔。该古人的DNA序列非常原始,对人类起源学说提出质疑。该学说认为现代人的祖先最早诞生于非洲,并且在10万年前由非洲向全球其他地方迁移。对于现代人类DNA的研究也再三表明,今天的人类起源于非洲。通过分

The doctrine holds that the ancestors of modern people were born at the earliest in Africa and migrated from Africa to other parts of the world 100,000 years ago. Studies of modern human DNA have shown repeatedly that humans today originate in Africa. Passed
