说明一个常识性的问题，很多人认为中国无玉米，其实不然，中国是没有美洲玉米，但是我们吃的“粘玉米”却真的是起源于中国的，与外来的玉米无关。至少我听说如此。

玉米的意义在于其高产 而且土地质量要求不高
如果你所说的 中国产的“粘玉米”和以上玉米定义拥有一样的特性的话
中国的人口爆炸 也不会等到清朝才发生了
所以即使“粘玉米”真是中国产的 那也没有意义
真正有意义的玉米种子来源 还是来自于其他地方

汉代壁画骑射

More surprisingly, perhaps, some mid 13th-century Norwegian knights were described as being skilled archers on horseback, though in hunting rather than warfare. Quite how that skill reached Scandinavia remains unknown, but it might have been brought back by Scandinavian warriors who had earlier served in the Byzantine Emperor's Varangian Guard.

Homer describes the bow of Pandarus: 'His polished bow was made from the horns of an ibex that he had shot. They measured sixteen hand spans. A bowmaker worked on them, joined them together, smoothed them and set a nock of gold at each end. Pandarus strung the bow, opened his quiver, chose an arrow and fitted it to the string. He held the arrow nock on the string of sinew and drew back the string to his breast until the iron arrowhead touched the bow. When he had drawn the great bow to full compass, he loosed the string, which sang the sharp arrow into the air.'
