現(xiàn)在有很多小動(dòng)物都變成了人類的寵物，老鼠也不例外，有時(shí)候去寵物店的話你也能看見大大小小的老鼠。

　　researchers from the university of osaka claimed that a genetically-engineered mouse that tweets like a bird has been produced, and they hope this discovery can help find how human language evolved over history。
　　日本大阪大學(xué)的科學(xué)家日前宣稱，他們已培育出了一只能像小鳥般鳴叫的老鼠，并希望借此了解人類語言在歷史長河中的進(jìn)化過程。
　　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(jìn)化鼠項(xiàng)目”旨在探索基因突變推動(dòng)進(jìn)化的機(jī)制，作為該項(xiàng)目的一部分，研究人員對(duì)具有基因變異傾向的老鼠進(jìn)行數(shù)代雜交，并逐個(gè)檢查新生鼠。終于有一天發(fā)現(xiàn)一只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，還有一只擁有短肢，而另外一只則長有和達(dá)克斯狗一樣的尾巴。
　　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(guān)人類語言進(jìn)化的線索。畢竟老鼠和人類在生物學(xué)以及大腦構(gòu)成方面更為接近，通過觀察老鼠群體中如何產(chǎn)生會(huì)唱歌的老鼠，并在特殊情況下進(jìn)行研究，科學(xué)家們有可能發(fā)現(xiàn)人類語言的起源，以及語言如何在群體內(nèi)傳播。
