WHEN a species evolves traits that seem to have little to do with individual survival-bright colours, say, or oversize horns, it is typically the male alone who sports these excesses.
如果一个物种是从进化源头一步步进化过来的(分类学家们这么认为),总属分化出来的各个分属里的物种应当具有相同的特征。
If it is to reflect its evolutionary origins (as taxonomists would prefer) the genus needs to be divided up into many more smaller genera in which the species have similar characteristics.
对于这样的发现,起初大家是想都不敢想,但现在事实就摆在眼前,他们的确发现了某物种单一个体的骨骼化石,而且完整得就如同露西一样,但在某些特征上,它又不同于露西,甚至和以前所发现的所有古人类化石都不一样。
