更新紀(jì)靈長(zhǎng)動(dòng)物,南方古猿

Some researchers see the australopithecine mouth as sculpted for munching small, hard objects such as seeds. 一些研究人員把南方古猿的嘴看作是用力咀嚼如種子一樣小而硬的食物的造型。

Perhaps 20 or more hominids (not all of them our ancestors) fill the gap between Lucy the australopithecine and modern humans. 在阿法南猿（露西）與現(xiàn)代人之間，人科動(dòng)物的化石也許超過(guò)20種（他們不全是我們的祖先）。

Yet it was only as tall as a modern three-year-old, and its brain was as small as the smallest australopithecine brain known. 從她的牙齒與磨耗痕判斷，她已成年。然而，她的身高只相當(dāng)于現(xiàn)代人的三歲娃兒，腦子與最小的南猿人一般大。

And that, says Strait, suggests that simplistic ideas about australopithecine diets, based on tooth and jaw size, and why they went extinct, need to be reevaluated. 斯特雷特還說(shuō)，根據(jù)牙齒和顎的大小提出的關(guān)于南方古猿日常飲食以及它們?yōu)槭裁礈缃^的過(guò)分簡(jiǎn)單的想法需要重新評(píng)估。
