Purpose of Life: Pass it on

I don't feel pain, fear, desire.
It's like all things that make us human are fading away.
It's like the less human I feel,
all these knowledge about... everything,
Quantum Physics, Applied Mathematics,
the infinite capacity of the cell's nucleus,
they're all exploding inside my brain, all these knowledge...
I don't know what to do with it.

If you're asking me what to do,
You know..
If you think about, the very nature of life,
I mean, from the very beginning...
The development of the first cell, divided into two cells.
This whole purpose of life has been...
passed on what was learned.
There's no higher purpose.
So if you're asking me what to do with all these knowledge you're accumulating,
I'd say...
Pass it on.
Just like any simple cell, going through time.

露西（英语：Lucy; Australopithecus afarensis）是一具发现于东非的古人类化石标本。此标本具有约40%的阿法南方古猿骨架，由唐纳德·约翰森等人于1974年在埃塞俄比亚阿法尔谷底阿瓦什山谷的哈达尔发现。露西生活于约320万年以前并被归类人族，这副骨架具有类似猿的脑容量和类似于人类的二足直立行走方式，支持了人类进化争论中直立行走在脑容量之前的看法。约翰森根据骨盆开口宽度认为此此样品是雌性。

露西仅有1.1米（3英尺7英寸）高，重29kg（64lb），外观上类似于黑猩猩。尽管该个体脑容量小，其骨盆和腿骨的功能几乎和现代人类相同，显示这些原始人类已可直立行走。

1992年发现了更完整的早期人科动物的骨架，但直到2009年10月完整结果才被公布。这具骨架被命名为阿尔迪，化石年龄约440万年。
