Early crest animals and the insight they provide into the evolutionary origin of craniatesJun Yuan Chen
LPS of Nanjing Institute of Geology and Paleontology, Institute of Evo Developmental Biology, and State Key Laboratory of Pharmaceutical Biotechnology, Nanjing University, Nanjing, China
Genesis 46:623-39. 2008..But, they lack ears, a clear telencephalon, and a skull. Furthermore, comparison of the brains of amphioxus and craniates suggests that the tripartite brain with telencephalon was not an older structure but a novelty of the craniates...
A possible Lower Cambrian chaetognath (arrow worm)Jun-Yuan Chen
Nanjing Institute of Geology and Palaeontology, Nanjing 210008, China
Science 298:187. 2002
The first tunicate from the Early Cambrian of South ChinaJun Yuan Chen
Nanjing Institute of Geology and Palaeontology, Nanjing 210008, China
Proc Natl Acad Sci U S A 100:8314-8. 2003..Based on new, more complete "Cheungkongella" specimens that show branching tentacles, this form may be a lophophorate, and in any case is not a tunicate...
Complex embryos displaying bilaterian characters from Precambrian Doushantuo phosphate deposits, Weng'an, Guizhou, ChinaJun Yuan Chen
LPS of Nanjing Institute of Geology and Paleontology, Institute of Evo Developmental Biology, State Key Laboratory of Pharmaceutical Biotechnology, Nanjing University, Nanjing 210093, China
Proc Natl Acad Sci U S A 106:19056-60. 2009....
Small bilaterian fossils from 40 to 55 million years before the cambrianJun Yuan Chen
Nanjing Institute of Geology and Paleontology, Nanjing 210008, China
Science 305:218-22. 2004..The structural complexity is that of an adult rather than a larval form. These fossils provide the first evidence confirming the phylogenetic inference that Bilateria arose well before the Cambrian...
The sudden appearance of diverse animal body plansduring the Cambrian explosionJun Yuan Chen
Institute of Evo Developmental Biology, Nanjing University, China
Int J Dev Biol 53:733-51. 2009..The anatomy of Early Cambrian crest animals, including Haikouella and Yunnanozoon, contributes to novel understanding and discussion for the origins of the vertebrate brain, neural crest cells, branchial system and vertebrae...
An Early Cambrian problematic fossil: Vetustovermis and its possible affinitiesJun Yuan Chen
Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, Nanjing 210008, China
Proc Biol Sci 272:2003-7. 2005....
Phosphatized polar lobe-forming embryos from the Precambrian of southwest ChinaJun Yuan Chen
Nanjing Institute of Geology and Paleontology, Institute of Evo Developmental Biology, and State Key Laboratory of Pharmaceutical Biotechnology, Nanjing University, Nanjing 210093, China
Science 312:1644-6. 2006..These data imply that lobe formation is an evolutionarily ancient process of embryonic specification...
Raman spectra of a Lower Cambrian ctenophore embryo from southwestern Shaanxi, ChinaJun Yuan Chen
Nanjing Institute of Geology and Palaeontology, Institute of Evo Developmental Biology, Nanjing University, Nanjing 210093, China
Proc Natl Acad Sci U S A 104:6289-92. 2007..The oldest ctenophore and the only embryonic comb jelly known from the fossil record, this exceptionally well preserved specimen provides important clues about the early evolution of the phylum Ctenophora and of metazoans in general...
Early Cambrian sipunculan worms from southwest ChinaDi-Ying Huang
Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, Nanjing 210008, China
Proc Biol Sci 271:1671-6. 2004..This study suggests that most typical features of extant sipunculans have undergone only limited changes since the Early Cambrian, thus indicating a possible evolutionary stasis over the past 520 Myr...
Evolution of vertebrate central nervous system is accompanied by novel expression changes of duplicate genesYuan Chen
State Key Laboratory of Genetic Resources and Evolution, Kunming Institute of Zoology, Chinese Academy of Sciences, Jiaochang East Road 32, Kunming 650223, China
J Genet Genomics 38:577-84. 2011..Our data accentuate the functional contribution of gene duplication in the CNS evolution of vertebrate and uncover an invertebrate non-CNS history for some vertebrate CNS-biased duplicate genes...
Identification and characterization of novel amphioxus microRNAs by Solexa sequencingXi Chen
Jiangsu Diabetes Center, State Key Laboratory of Pharmaceutical Biotechnology, School of Life Sciences, Nanjing University, Hankou Road, Nanjing, Jiangsu 210093, PR China
Genome Biol 10:R78. 2009..While the number of known human and murine miRNAs is continuously increasing, information regarding miRNAs from other species such as amphioxus remains limited...
Fossil sister group of craniates: predicted and foundJon Mallatt
School of Biological Sciences, Washington State University, Pullman, Washington 99164 4236, USA
J Morphol 258:1-31. 2003..Overall, Haikouella agrees so closely with recent predictions about pre-craniates that we conclude that the difficult problem of craniate origins is nearly solved...
Precambrian animal life: probable developmental and adult cnidarian forms from Southwest ChinaJun-Yuan Chen
CA Inst Technol, Pasadena
Dev Biol 248:182-96. 2002..It follows that at least stem group bilaterians must also have been present at this time...
