有些生物与祖先有着出人意料的差别,甚至一些祖先长着奇特的结构,例如3米高的史前巨猿、在陆地上奔跑的野猪鳄等。巨猿一位古人类学家发现一块灵长目动物的牙齿,推测这种灵长目物种身高达3米,体重约540多千克。相比之下,现代雄性银背大猩猩体重180多千克,仅是前者的三分之一。这种史前巨猿比北极熊更大,非常像人们描述的大脚野人。 Some creatures have an unexpected difference with their ancestors, and some even have peculiar structures such as prehistoric 3-meter-tall apes and wild boar on land. A Great Anthropologist An ancient anthropologist discovered the teeth of a primate animal, speculating that the primate species is up to 3 meters tall and weighing about 540 kilograms. In contrast, modern male silverback gorillas weigh more than 180 kilograms, only one-third of the former. This prehistoric giant ape is larger than a polar bear, much like the savage savanna described by people.
