Furthermore, the fossil had Neanderthal mitochondrial DNA. This is passed from mother to child,
此外，化石中有尼安德塔線粒體DNA。這是從母親基因中遺傳下來的，
which meant that either the teenager was the daughter of a Denisovan father and a Neanderthal mother
這意味著這個少女要么是一位丹尼索瓦父親和一位尼安德特母親的女兒
or had come from a population with an extensive mix of traits, and had been born to parents who were, in effect, hybrids.
要么是來自于廣泛性狀相結合的一個群體，并且她的父母其實是混血。
Biologists know that animal populations of mixed ancestry
生物學家知道那些沒經歷過什么進化變異的混血動物種群，
who are undergoing little evolutionary change show signs of this equilibrium in their genes.
它們的基因中就有這種平衡的跡象。
Drs Slon and Paabo looked for just such markers in the genes of their Denisovan teenager and found none.
斯隆和派伯并沒有在丹尼索瓦少女的基因中發現這種標記。
That ruled out the idea that she came from mixed ancestry.
他們排除了這位少女來自混血家族的想法。
They did, though, find that each chromosome pair the girl carried had one chromosome that was entirely Neanderthal in origin
雖然他們確實發現在女孩基因染色體對中有一個染色體完全屬于尼安德特人；
and one that was almost entirely Denisovan. This signified that she had one parent from each group.
另一個染色體基本完全屬于丹尼索瓦人。這表明她的父母分別來自這兩支。
Knowing that the mother was a Neanderthal from the girl's mitochondrial DNA, means that her father must have been a Denisovan.
從這位少女的線粒體DNA中，我們知曉她的母親是尼安德特人，這意味著她的父親一定是丹尼索瓦人。
The 2013 analysis of the Denisovan fossil also showed interbreeding, albeit of a more distant sort.
2013年對丹尼索瓦人化石的分析也表明是異血緣交配，雖然這一支系更加遙遠。
Add in this latest research, and although Neanderthals and Denisovans may not have met very often,
再加上這個最新的研究，雖然尼安德特人和丹尼索瓦人并不經常見面，
sex between them is likely to have been more common than was previously realised.
但是他們之間的交配可能比我們之前所認為的更加普遍。
The implication is that modern humans are likely to have a messier genetic heritage than once thought.
這表明現代人類的遺傳遺傳比我們曾經以為的更加混亂。
