voice 1: Some scientists think that the damaged genes may be the ones that cause human beings to walk on two legs. If that is true, it would explain why the five young people cannot walk normally. These scientists think that other genes may have started working instead of the damaged genes. The scientists suggest that these genes are 'older'. They may be the genes that cause animals to walk on all four legs. They think that these genes could have existed in our ancient ancestors.
聲音1:一些科學家認為,這些損害基因與人類用兩條腿走路有關。如果這是真的,那就能解釋為什么這5名年輕人不能正常走路了。這些科學家認為,可能有其他基因代替這些受損基因工作??蒲Ъ胰銜?,這些基因很“古老”。它們可能是使動物用四條腿走路的基因。他們認為這些基因可能存在于我們的祖先身上。

Some scientists are saying that these five young people of the Ulas family represent a missing link with our ancestors. Uner Tan, a Turkish scientist, believes they are like a model. He thinks they demonstrate how human beings developed.
一些科學家表示,烏納塔恩家族的這5名年輕人代表了我們祖先“缺失的環節”。土耳其科學家認為,他們就像模型。他認為他們說明了人類的進化方式。
