Historically,large brains have been considered the fundamental human trait.In the 20s when Raymond Dart suggested a small brained creature walked upright he had only a skull to work with.Here was a significant portion of a skeleton a creature with some very ape like features that walked upright.Lucy had an ape like brain,a human like skeleton,and teeth both ape and human like a startling mixture of traits.Yet clearly she was a hominid,a member of the family of man.Returning to Hadar the following year,the team combed the slopes hoping to discover newly exposed fossils.They never dreamed they would find anything as exciting as Lucy.But the Johanson luck proved even better than the year before.We have the femur and the foot and the knee' They had come across the first fragments of 13 individuals,possibly members of the same band.They may have all perished together perhaps in a flash flood.The fossils from Hadar and similar ones from Tanzania represent from 35 to 65 individuals.Based on the abundant evidence,Johanson and his colleagues felt confident in announcing an entirely new species.They called it Australopithecus afarensis and put forth the still controversial idea that it is the common ancestor to other Australopithecines who eventually died out,as well as the line that led to true humans.In the laboratory fragments of skulls and jaws from several males were combined into a composite plaster skull by Johanson's colleague,Dr.Tim White.After initial discovery and analysis scientists rarely work with an original,fragile fossil.In fact,the fossils are usually returned to the country where they were found.But these durable casts are exact replicas down to the most minute details.In Alexandria,Virginia,the composite skull begins a magical transformation in the hands of anthropologist turned artist,John Gurche.

从历史上看,大的脑子被认为是人类基本的特质.20年代当雷蒙德灾难援助反应队提出了一个小脑的生物直立行走他只有一个头骨与之共事的人.这里是一个骷髅的一个重要部分生物与一些非常猿喜欢直立行走的特征.露西有像猿,人类的大脑像骷髅,牙齿都和真人一样,都要发疯了一个令人吃惊的混合的特征.但是很清楚,她是人类,家里的一员的男人.回到Hadar次年,球队梳理了斜坡希望能找到新暴露的化石.他们从来没想过他们会发现任何令人兴奋,露西.但Johanson证明运气甚至比去年这个时间.我们有股骨和脚,膝盖”他们碰到第一个碎片13个人,可能同一个乐队的成员.他们可能所有人就一同死亡或许在突发的洪水.Hadar和类似的化石的代表在35到从坦桑尼亚65个人.摘要依据丰富的证据,Johanson和他的同事们有信心,在宣布一个完全新的物种.他们称它为南方古猿属和提出的这个仍然是一个有争议的想法共同的祖先其他南猿人最终死出去,以及线,导致了真正的人类.在实验室里用骷髅头骨的碎片从几男性和《大白鲨》合并为一个复合石膏头骨Johanson的同事,患病的姆怀特.在初始发现和分析工作科学家很少原、易碎的化石.事实上,化石是通常返回了家园,他们被发现.但是这些耐用铸件下确切的复制品的最细小的细节.在弗吉尼亚州的亚历山大,复合头骨开始了神奇的转型的手上艺术家,约翰Gurche了人类学家.
