日本培育會唱歌老鼠 像小鳥般鳴叫

As part of the "Evolved Mouse Project," which was carried out to find how genetic mutations drive evolutions, researchers cross-bred the mutation prone mice for generations and checked the newborn mice one at a time. Finally one day they came across a mouse that was singing just like a bird.

“進化鼠項目”旨在探索基因突變推動進化的機制，作爲該項目的一部分，研究人員對具有基因變異傾向的老鼠進行數代雜交，並逐個檢查新生鼠。終於有一天發現一隻老鼠能像鳥一樣鳴叫。

In addition to the singing rodent, there are also a mouse with short limbs and one with a tail like of a dachshund among the 100 mutant mice.

此外，在他們培育的100只老鼠中，還有一隻擁有短肢，而另外一隻則長有和達克斯狗一樣的尾巴。

日本培育出“會唱歌”的變異鼠

Researchers now hope their tweeting mice will lend insight on how human language evolved over history. Mice, after all, are much closer to humans in terms of biology and brain, and by seeing how they chirp in the company of other mice and when placed in certain situations, they might learn how human linguistics came to be as well as how they were shared among groups.

如今研究人員希望他們的“唱歌”老鼠可以提供有關人類語言進化的線索。畢竟老鼠和人類在生物學以及大腦構成方面更爲接近，通過觀察老鼠羣體中如何產生會唱歌的老鼠，並在特殊情況下進行研究，科學家們有可能發現人類語言的起源，以及語言如何在羣體內傳播。
