On the basis of putative nuclei and endospores, Huldtgren et al. (Reports, 23 December 2011, p. 1696) propose that embryo-like Doushantuo microfossils are nonmetazoan holozoans akin to mesomycetozoeans. However, both size and preservation preclude interpretation of internal structures as nuclei. Moreover, the authors may have conflated two different populations; some specimens display a pseudoparenchymatous organization incompatible with a mesomycetozoean comparison.
基于假定的核和内生孢子,Huldtgren 等人(报告,2011 年 12 月 23 日,第 1696 页)提出,胚胎状的陡山沱微体化石是非动物的真后生动物,类似于粘菌动物。然而,大小和保存情况都排除了将内部结构解释为核的可能性。此外,作者可能混淆了两个不同的群体;一些标本显示出与粘菌动物比较不兼容的假组织状组织。
