The biological answer is simple: a member of the species Homo sapiens that is characterized by such features as a relatively large brain set in a globular braincase, small brow ridges over the eyes, a small retracted face, a chin on the lower jaw, and a lightly built skeleton. Many of modern humans’ biological traits – at least those that can be preserved as fossils – were already present in Africa and Israel more than 100,000 years ago.
伦敦—如何定义现代人？生物学答案很简单：智人的一员，并具有相对较大的脑组织和容纳脑组织的球状脑壳，眼睛上方有较小的眉骨，较小的可伸缩的面部，下颚处有下巴，骨骼较轻。许多现代人的生物学特征——至少从保留下来的化石看——至少在10万多年前便已出现于非洲和以色列。
