德西尔瓦说,即使存在着一定幅度的误差,结果还是很明显,南猿幼儿的出生重量更接近于现代人类,即占母体重量的6%,而不是类人猿的3%。
Even with that margin of error, DeSilva says, it was clear that the birth weight of Australopithecus infants was much closer to the 6 percent of modern humans than the 3 percent of apes.
这种方法可以精确地运用于所有灵长类。德西尔瓦有一打南猿头骨可供他分析。
That can be done very accurately for all primates, and DeSilva was able to analyze a dozen Australopithecus skulls.
