“…A number of phylogenies have been proposed (e.g. Huang et al 2004c), and in addition it is worth noting that some worms identified as phoronids (Eophoronis, see Chen 2004, fig. 331, 332; and Iotuba, see Chen & Zhou 1997, fig.…”

The Cambrian 'explosion' is widely regarded as one of the fulcrum points in the history of life, yet its origins and causes remain deeply controversial. New data from the fossil record, especially of Burgess Shale-type Lagerstätten, indicate, however, that the assembly of bodyplans is not only largely a Cambrian phenomenon, but can already be documented in fair detail. This speaks against a much more ancient origin of the metazoans, and current work is doing much to reconcile the apparent discrepancies between the fossil record, including the Ediacaran assemblages of latest Neoproterozoic age and molecular 'clocks'. Hypotheses to explain the Cambrian 'explosion' continue to be generated, but the recurrent confusion of cause and effect suggests that the wrong sort of question is being asked. Here I propose that despite its step-like function this evolutionary event is the inevitable consequence of Earth and biospheric change.

“…Huang et al [8] revised X. peculiaris and erected a new genus and species Yunnanpriapulus halteroformis. Xiaoheiqingella and Yunnanpriapulus are assigned to the Recent family Priapulidae thus suggesting that the ancestors of this important family existed in the Early Cambrian already (evolutionary stasis).…”

“…Han et al described a new palaeonscolecidan worm from the Maotianshan Shale namely Tabelliscolex [7] . Huang et al [8] revised Xiaoheiqingella and described a new genus Yunnanpriapulus that was placed in the Recent family Priapulidae. Huang et al [9] revised Corynetis and described a new genus Anningvermis (with studies on the functional morphology), and two extinct priapulid families, namely the Corynetidae and the Anningidae erected.…”

“…Most Cambrian priapulids are thought to be predators (Conway Morris 1977;Bruton 2001;Huang et al 2004b;Hu 2005;Huang 2005Huang , 2006. The Guanshan priapulids, including both the palaeoscolecidans and corynetiids, are also interpreted as predators because of their spiny pharynxes, which are comparable to those of their modern analogues.…”

“…The early Cambrian Chengjiang fossil Lagerstätte yields the most diverse record of fossil priapulids (Han et al 2003(Han et al , 2004Hou et al 2004;Huang et al 2004a, b;Huang 2005). Although the controversy about their affinities continues, most authors have accepted the hypothesis that palaeoscolecidans represent a special group of priapulids (Conway Morris 1997, Wills 1998, Huang et al 2004b, Hu 2005, Huang 2006, Harvey et al 2010. Fossil records of palaeoscolecidans range from Cambrian Series 2 to late Silurian (Whittard 1953, Glaessner 1979, Mikulic et al 1985, Conway Morris & Robison 1986, Kraft & Mergl 1989, Hintz et al 1990, Müller & Hinz-Schallreuter 1993, Zhang & Pratt 1996, Ivantsov & Wrona 2004, Lehnert & Kraft 2006.…”
