Scientists from Japan and Russia believe it may be possible to clone a mammoth after finding well-preserved bone marrow in a thigh bone recovered from permafrost soil in Siberia, AFP reported.

They will launch a joint research project next year that aims to recreate the giant mammal, said Kyodo News.

The scientists plan to use a nuclei with undamaged genes they found to reproduce the mammoth's DNA.

The discovery in August of the well-preserved thigh bone in Siberia has increased the chances of a successful cloning.

Mammoths became extinct about 10,000 years ago. （點(diǎn)擊雅虎新聞網(wǎng)站查看原文）

日俄嘗試復(fù)活猛犸象

???????據(jù)法新社報(bào)道，來自日本和俄羅斯的科學(xué)家在西伯利亞的永久凍土中發(fā)現(xiàn)了一份保存完好的猛犸象大腿骨骨髓，他們因此確信有可能克隆這種動(dòng)物。

???????據(jù)日本共同社報(bào)道，這些科學(xué)家將于明年共同展開一項(xiàng)計(jì)劃，旨在復(fù)活這種巨型哺乳動(dòng)物。

???????科學(xué)家計(jì)劃使用發(fā)現(xiàn)的無損細(xì)胞核來復(fù)制猛犸象的DNA。

???????今年8月在西伯利亞發(fā)現(xiàn)保存完好的腿骨后，克隆成功的可能相應(yīng)增加。

???????猛犸象大約一萬年前滅絕。
