bipedal

But he offers another speculation: later, after they became bipedal and had more bare skin, their backs would have been exposed to the air as they knelt or bent over to forage.

但他也提供了另一个猜想：后来，当人类变成直立行走并已脱掉部分体毛之后，当他们跪下或弯腰搜寻食物时，背部会较多地暴露在空气中。

The transition to humanity is generally agreed to have occurred between Australopithecus, a genus of small-brained, bipedal primates whose most famous member is a fossil nicknamed "Lucy," and the big-brained species Homo erectus.

人们普遍认为人类是由南方古猿和直立人之间的某个物种演化而来。南方古猿头部较小，属双足灵长类动物，其最有名的家族成员是一具被称做“露西”的化石，比较而言，直立人的头部就大多了。

This megalosaurus for instance is a shame walking on all four legs, but we now know he would have be bipedal if he would have stood on just his hind legs and his forelegs would have been quite small and lifted it right up off the ground.

例如，这只用四脚走路的斑龙就是个遗憾，但现在我们知道，如果它是两足动物，它会只用后腿走路，那么前腿就会很小，可以直接从地面举起。
