古代人类杂交

在本周的问题中，由Viviane Slon和SvantePääbo领导的团队揭示了混合尼安德特人和杰尼索夫血统的第一代后代的基因组。 古代青少年的基因组来自从西伯利亚阿尔泰山脉的Denisova洞穴中回收的骨碎片。 这位年轻女性在5万至9万年前去世时至少有13岁。 尼安德特人和杰尼索瓦人在欧亚大陆共存，之前发现了一些混合遗产的标本。 但最新发现是首次发现第一代儿童，这为两组之间的杂交提供了直接证据。 研究人员提出，群体之间的杂交可能在他们遇到时很常见，但有限的相互作用使这些群体在遗传上保持不同。 显示较少

Ancient human hybrid

In this week’s issue, a team led by Viviane Slon and Svante Pääbo reveals the genome of a first-generation offspring of mixed Neanderthal and Denisovan parentage. The genome of the ancient adolescent was obtained from a bone fragment recovered from the Denisova Cave in the Altai Mountains of Siberia. The young female was at least 13 years old when she died 50,000–90,000 years ago. Neanderthals and Denisovans coexisted in Eurasia, and some specimens of mixed heritage have previously been found. But the latest discovery is the first time a first-generation child has been identified, providing direct evidence of interbreeding between the two groups. The researchers suggest that interbreeding between the groups may have been common when they met but that limited interactions allowed the groups to remain genetically distinct. show less
