Abstract

Strausfeld . (Report, 24 Nov 2022, p. 905) claim that Cambrian fossilized nervous tissue supports the interpretation that the ancestral panarthropod brain was tripartite and unsegmented. We argue that this conclusion is unsupported, and developmental data from living onychophorans contradict it.

摘要

斯特劳斯费尔德等人（报道，2022 年 11 月 24 日，第 905 页）声称，寒武纪化石化的神经组织支持这样一种解释，即原始节肢动物的大脑是三部分的，没有分段。我们认为，这一结论没有依据，而且现生有爪动物的发育数据与之相矛盾。
