By analyzing the genomes of 28 bears—polar bears,
including a roughly 120,000-year-old specimen from
Norway's Svalbard archipelago, as well as modern
brown bears and black bears—the scientists in effect
read back in time to a common ancestor at least four
million years ago. That finding conflicts with a genetic
analysis published in Science earlier this year that
suggested the species was only 600,000 years old or so,
which the team behind the new research suggests may
result from misreading past interbreeding events with
closely related brown bears.
自己的大意理解：
似乎是在說明從來自12萬年前挪威Svalbard群島的標本
研究包括北極熊 棕熊 黑熊
以及來自研讀400萬年前的共同祖先的資料後 發現結果與
今年稍早之前的一份研究資料產生牴觸 好像僅有60萬年?
而會有這樣的衝突是因為誤解了關係極為接近的棕熊在異種
雜交上的事件上?
不曉得這樣的理解是不是對的@@?
