“日本护士XXXXX18一20”考古学家发日本护士XXXXX18一20现4000年前玛雅人祖先使用的鱼渠

  中新日本护士XXXXX18一20网北京11月23日电 日本护士XXXXX18一20 美国《科学进展》杂志22日发表的一项新研究称,考古学家在中美洲发现玛雅人祖先4000年前用于捕鱼的渠道。

  研究称,考古学家利用无人机和谷歌地球影像等技术手段在中美洲的伯利兹发现一个有4000年历史的渠道网络。研究小组随后在该国一处野生动物保护区进行挖掘。据美联社报道,该项研究的作者之一、新罕布什尔大学教授埃莉诺哈里森巴克说,航空图像对于辨认这种贯穿湿地数英里(1英里约合1.6公里)的之字形渠道至关重要。

  这些古老的鱼渠与蓄水池相配合,用于疏导和捕捉淡水鱼类。新研究的另一名作者、佛蒙特大学助理教授玛丽卡布劳威尔伯格说,在附近发现的“带刺矛尖”可能是绑在木棍上用于叉鱼的。

  早在4000年前,尤卡坦半岛沿海平原的半游牧民族就开始修建水渠网络。新研究称,这些渠道使用了大约1000年或更久,其中包括玛雅人开始定居在永久性农耕村落并逐步形成独特文化的时期。

  玛雅社会有发达的农业、数学、历法、艺术和天文学,制陶和纺织技艺也很精湛。22日发表的新研究揭示了当地早期人类与后来出现的玛雅文化之间的联系。这些鱼渠帮助早期居民实现饮食多样化,养活不断增长的人口,为后来的文化发展奠定基础。(完)
