It was against this background that Dubois began his search for ancient human bones.

正是在这样的背景之下，杜布瓦开始了他寻找古人类化石的工作。

Homo heidelbergensis, Homo rhodesiensis, Neandertals, and Dubois's Java Man-but all that was about to change in a very big way.

海德尔堡人、罗德西亚人、尼安德特人，以及杜布瓦的爪哇人——但是很快，这一切就将发生根本性改观。

Dubois called it Anthropithecus erectus (later changed for technical reasons to Pithecanthropus erectus) and declared it the missing link between apes and humans.

杜布瓦称他为直立（后来因技术原因改称为直立猿人），并且宣称这是联结猿和人类之间的缺环。

Let’s go to the Thought Bubble to look at one of Dubois’ early studies of these disparities.

让我们到 Thought Bubble 看看 Dubois 对这些差异的早期研究之一。

Dubois went knocking on doors, asking people questions about themselves and their families.

Dubois 去敲门，询问人们有关他们自己和家人的问题。

This quote reveals a really critical underlying thread in much of Dubois’ work – the idea of double-consciousness.

这句话揭示了杜波依斯大部分作品中真正关键的潜在线索——双重意识的想法。

It’s hard to express just how radical Dubois’ conclusions were at the time.

很难表达当时杜波依斯的结论有多么激进。

At about the time that Dubois was setting out for Sumatra, a skeleton found in Perigueux was confidently declared to be that of an Eskimo.

就在杜布瓦出发去苏门答腊前后，有人在佩里格发现了一副骸骨；它被很有把握地宣布为爱斯基摩人的化石。

Dart could see at once that the Taung skull was not of a Homo erectus like Dubois's Java Man, but from an earlier, more apelike creature.

达特马上发现，这并非是杜布瓦发现的爪哇人那样的直立人，而是与猿更为接近的远古猿人。

If it is an erectus bone, it is unlike any other found since. Nonetheless Dubois used the thighbone to deduce-correctly, as it turned out-that Pithecanthropus walked upright.

即使是一根直立人的骨头，它也与已经发现的其他化石不同。杜布瓦据此推论——后来证明是正确的——类人猿是直立行走的。
