Re: [請益] 這段文字的大意？
※ 引述《campfire (為什麼要叫小妹)》之銘言：
: 文章來源：http://www.scientificamerican.com/
: 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.
剛又重新想了一下 大意是不是：
一項經由染色體對於28種熊類（北極熊）的分析 包含了12萬年前
挪威Svalbard群島的標本 這當中也含有現代棕熊和黑熊的樣本.
科學家實際上追蹤到牠們400萬年前的共同祖先.
這些發現與基因分析有所衝突 這個報告在今年初有發表過並指出
實際約只有60萬年.
而導致這樣的研究衝突 有可能是對過去棕熊異種交配的誤解.
不知道是不是這個大意@@
因為個人真滿喜歡這類自然題材的文章 雖然看得很吃力
不過一定要堅持!!!!!
