今天亮相的“露西(Lucy)”骨骼化石是该化石唯一的一具复制品，之前一直在埃塞俄比亚国家博物馆展示。
"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 cranialcapacity of "Lucy" was 400cc with the average human from that period from 300 cc to 500 cc. Male cranial capacity was slightly larger. In comparison, modern human cranial capacity is between 1300cc to 1500cc on average.
据科学记载，“露西(Lucy)”是1974年在埃塞俄比亚发现的南方古猿阿法种的古人类化石的代称。这是一具完整性40%的女性骨架，生前才20多岁，根据其骨盆推算生过孩子，脑容量为400毫升（注：当时脑容量的平均值为300毫升-500毫升，男性比女性略高一些。现代人类的脑容量平均值为1300～1500毫升）。
The nickname of "Lucy" was given to the fossilswhile the discoverers played the Beatles song "Lucy in the Sky with Diamonds" to celebrate the find.
“露西”生活的年代是320万年前，因此被认为属于第一批直立行走的人类，是目前所知人类的最早祖先。这具南方古猿化石之所以取名“露西”，缘于发现者在当时播放了一首披头士乐队的歌《Lucy in the Sky with Diamonds》，于是这具化石便被命名为“露西(Lucy)”。
