320 萬年前的原始人“露西”骨骼化石在非洲聯(lián)合館埃塞俄比亞展區(qū)正式亮相。

‘Lucy’was the nickname of a set of several hundred pieces of bones of about 40%of the female skeleton of an individual Australopithecus afarensis,found in 1974 in Ethiopia.(The cranial capacity(腦容量)of ‘Lucy’was 400cc with the average human from that period from 300cc to 500cc.Male cranial capacity was a little larger.In comparison,modern human cranial capacity is between 1300cc to 1500cc on average.)

據(jù)科學(xué)記載，“露西”是1974年在埃塞俄比亞發(fā)現(xiàn)的南方古猿阿法種的古人類化石的代稱。這是一具完整性40%的女性骨架（腦容量為400毫升，當時腦容量的平均值為300～500毫升，男性比女性略高一些?，F(xiàn)代人類的腦容量平均值為1300～1500毫升。）

‘Lucy’is believed to be the first human to walk upright,and she s the earliest ancestor of human beings,as we have known so far.The nickname of‘Lucy’was given to the fossils while the discoverers played he Beatles song ‘Lucy in the Sky with Diamonds’ to celebrate the discovery.

“露西”被認為屬于第一批直立行走的人類，是目前所知人類的最早祖先。這具南方古猿化石之所以取名“露西”，緣于發(fā)現(xiàn)者在當時播放了一首披頭士樂隊的歌“Lucy in the Sky with Diamonds”，于是這具化石便被命名為“露西”
