怎么可能?考古学家理查德满脸的不可思议,他把化石报告反复看了好几遍。一万年前灭绝的洞熊虽然个头很大,但印象中的它一直是温顺的植食动物,很多关于洞熊化石的研究都证明了这一点,而现在他手上拿着的报告却显示着,洞熊是一种极其凶猛的肉食动物。理查德对此充满了疑问、好奇还有不安,他不敢想象,倘若这是真的,洞熊将是人类祖先多么可怕的敌人! How is it possible? Archaeologist Richard face incredible, he repeated the fossil report read several times. The cave bear, extinct ten thousand years ago, was big but the impression was that it had been a gentle herbivore and many studies of cave and fossil prove this, and now his report on his hand shows The cave bear is an extremely ferocious carnivore. Richard is full of doubt, curiosity and anxiety, he can not imagine, if this is true, cave bears will be how terrible the enemy of human ancestors!
