To celebrate over 100 years of achievements in Chinese palaeontology, this issue selects the latest studies on three key evolutionary transitions, to address how Chinese palaeontological research impacts our understanding of evolutionary history. 1) Origin and early diversification of multicellular organisms, including embryo-like fossils from the Ediacaran Weng’an Biota, early arthropods from the Cambrian Chengjiang Biota and phytoplankton changes from the Cambrian to Ordovician. 2) Terrestrial organisms and ecosystems, including early land plants in the Devonian, new evidence of pterosaur diets from the Late Jurassic Yanliao Biota, a new mammal from the Early Cretaceous Jehol Biota, colouration of a new mid-Cretaceous amber insect, and a new monitor lizard from the Eocene. 3) Palaeoanthropology, focusing on hominin evolution and diversity.
