科学家发现现代人类是两个古老种群的遗传组合,它们分裂并重新团聚。
Scientists discover modern humans are a genetic mix of two ancient populations that split and then reunited.
剑桥大学的研究人员发现,现代人类可能起源于两个古代人口的基因混合,这两个古代人口大约150万年前分离,大约30万年前重新团聚。
Researchers at the University of Cambridge have found that modern humans likely resulted from a genetic mix between two ancient populations that separated around 1.5 million years ago and reunited about 300,000 years ago.
一个群体贡献了今天人类基因构成的80%,另一个群体贡献了另外20%。
One group contributed 80% and the other 20% of the genetic makeup of today's humans.
这一发现刊登在《自然遗传学》上,与以前关于人类从单一血统演变的信念相矛盾,突出了人类起源的复杂性。
This discovery, published in Nature Genetics, contradicts the previous belief that humans evolved from a single lineage and highlights the complexity of human origins.
