一个国际团队在《自然》杂志上报告说,他们注意到“始虫”形成化石后,其神经部位依然沉淀有铁、铜等金属物质,于是利用X光照射,使这些金属物质发光后,再用CT扫描将图像拍摄下来,首次得到了几乎完整保留下来的“始虫”神经系统图像。研究人员对“始虫”从头部到尾部的中枢神经系统进行了精密分析,并与蝎子和鲎的神经系统进行了比较。日本海洋研究开发机构研究员田中源吾介绍说,“始虫”中枢神经系统的排列与现在的蝎子、蜘蛛和鲎等一致,应该就是它们的远祖。
An international team reported in the journal Nature that they noticed that after the fossil was formed, their nerve sites were still precipitated with metallic substances such as iron and copper. X-rays were then used to make these metallic substances glow , And then CT scan the image taken down, for the first time has been almost completely preserved “Insects ” nervous system images. The researchers conducted a rigorous analysis of the central nervous system from the head to the tail and the comparison with the nervous system of the scorpion and the goblet. Japan Marine Research and Development Institute researcher Tanaka Yuen said that “start insects ” arrangement of the central nervous system and the current scorpions, spiders and 鲎 and so on, should be their ancestors.
