中国地质大学和西北大学教授舒德干等人在早期动物演化研究上又有重大突破性成果——在中国澄江发现棘皮动物始祖化石(图1),并结合以往半索动物、头索动物、尾索动物等重要发现,首次勾勒出了既包括现生主要类群、同时也包括多种重要绝灭类群在内的迄今最完整的后口动物演化谱系轮廓(图2) China University of Geosciences and Northwestern University professor Shu Deqian et al. Have also made major breakthroughs in the study of early evolution of animals - the echinoderms of the echinoderm were found in Chengjiang, China (Figure 1), and combined with the past half-carnivores, For the first time, the most complete discovery of the evolutionary phylogenetic profile of posterior animals including both the major genera and the major extinction groups has been sketched out for the first time (Figure 2)
