Spatiotemporal transcriptomics reveals the evolutionary history of the endoderm germ layer
Spatiotemporal transcriptomics reveals the evolutionary history of the endoderm germ layer is a scholarly work by Michal Levin, Itai Yanai, and Brian K. Hall, published in 2014 in ''Nature''. The main subjects of the publication include ageing, endoderm, biology, transcriptome, cell biology, anatomy, germ layer, mesoderm, developmental biology, evolutionary biology, ectoderm, FGF and mesoderm formation, genetics, embryo, transcriptomics, and Cnidaria. Of the three germ layers, the mesoderm is found in bilaterian animals but is absent in species in the phyla Cnidaria and Ctenophora, which has been taken as evidence that the mesoderm was the final germ layer to evolve.
