Description:
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.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xiao, Shuhai -- Knoll, Andrew H -- Schiffbauer, James D -- Zhou, Chuanming -- Yuan, Xunlai -- New York, N.Y. -- Science. 2012 Mar 9;335(6073):1169; author reply 1169. doi: 10.1126/science.1218814.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geosciences, Virginia Polytechnic Institute and State University, Blacksburg, VA 24061, USA. xiao@vt.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22403373" target="_blank"〉PubMed〈/a〉
