古代人類雜交

在本周的問題中，由Viviane Slon和SvantePääbo領導的團隊揭示了混合尼安德特人和傑尼索夫血統的第一代後代的基因組。 古代青少年的基因組來自從西伯利亞阿爾泰山脈的Denisova洞穴中回收的骨碎片。 這位年輕女性在5萬至9萬年前去世時至少有13歲。 尼安德特人和傑尼索瓦人在歐亞大陸共存，之前發現了一些混合遺產的標本。 但最新發現是首次發現第一代兒童，這為兩組之間的雜交提供了直接證據。 研究人員提出，群體之間的雜交可能在他們遇到時很常見，但有限的相互作用使這些群體在遺傳上保持不同。 顯示較少

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
