Ambulacraria Ambulacraria Ambulacraria or Coelomopora is a Superphylum of invertebrate phyla which includes echinoderms and hemichordates; a member of this group is called an ambulacrarian. Phylogenetic analysis suggest the echinoderms and hemichordates separated around 533 million years ago. The Ambulacraria are part of the deuterostomes, a larger clade that also includes the Chordata, Vetulicolia and Saccorhytus. The two living clades with representative organisms are: The group Xenoturbellida (two species of worm-like animals) has previously been considered to be in this clade, but is now considered to be placed more basally among Metazoans. Fossil taxa that may lie on the stem lineage:
Han Chinese subgroups in parts of Guangdong, Guangxi, Fujian, Jiangxi and Taiwan. They are one of the largest groups found among the Chinese in Southeast Asia. The origin of Gan-speaking peoples in China are from Jiangxi province in China. Gan-speaking populations are also found in Fujian, southern Anhui and Hubei provinces, and linguistic enclaves are found in Taiwan, Shaanxi, Sichuan, Zhejiang, Hunan, Hainan, Guangdong, Fujian and non-Gan speaking Jiangxi. Other minor subgroups include speakers of the Tanka people, Peranakans, Chuanqing, and Kwongsai people The culture of the Han Chinese is complex and diverse.
