This can be related to changes in one of the Hox genes called engrailed. To quote (Jacobs et al. 2000, "Onychophorans are thought to be the sister taxon of arthropods and are segmented. The head may bear paired dorso-lateral eyes and/or a pair of pre-ocular, non-sclerotized antenniform appendages.

The body is covered by paired, tuft-like papillae. Thanahita distos joins only seven other known three-dimensionally preserved lobopodian or onychophoran (velvet worm) fossil specimens and is the first lobopodian to be formally described from the Silurian.Several Cambrian "weird wonders" have also been linked with the arthropods. However, these relationships are difficult to express in traditional Linnean systematics. I present a morphological cladistic analysis of seven Vendian "arthropodlike" taxa compared with 21 representative Cambrian arthropods, lobopods, and weird wonders.Locomotory movements of individual lobopods of E. rowelli proved far more diverse than previously thought and might be governed by a complex interplay of 15 muscles, including one promotor, one remotor, one levator, one retractor, two depressors, two rotators, one flexor and two constrictors as well as muscles for stabilization and haemolymph ...The lobopods of Early Cambrian Chengjiang Lagerstätte.

Pseudopods do not always look like amorphous masses; Rather they may be classified by their distinctive appearances. They can be classified in the following varieties: lobopods, filopods, reticulopods and axopods. Functions of pseudopodia . Usually they have two functions: the locomotion and the capture of prey or the swallowing of food.The Lower Cambrian Chengjiang fauna is reviewed and shown to be closely comparable with the younger Burgess Shale fauna. but with various differences in detail. A diverse group of more or less annulated lobopod animals including 'armoured lobopods' are regarded as representatives of the phylum Onychophora.Budd, G.E. & Daley, A.C. 2011: The lobes and lobopods of Opabinia regalis from the middle Cambrian Burgess Shale. Lethaia, Vol. 45, pp. 83-95. Despite many papers devoted to it, the morphology of the Burgess Shale animal Opabinia regalis continues to excite controversy. In particular, the trunk region remains incompletely understood, leading to several recent attempts to interpret the fossil ...A pair of tiny, modified appendages are located immediately behind the head. [1] The most recognisable feature of Diania is the robust, spiny legs (walking lobopods [1]) which led to it being nicknamed "walking cactus". [2] [5] While the leg base is narrow and simple, the remaining sections are subequally robust to the trunk, [1] with 15 widely ...

Both these advances offer hope that the tardigrades (placed as the sister group to the euarthropods in many analyses of extant taxa, here collectively named the Tactopoda) may be more ...The Burgess Shale is not the sole record we have of a Cambrian soft-body deposit. In fact, there are over 50 individual Cambrian localities (see map below) known from around the world that show soft-body preservation, and more likely are waiting to be discovered.

These changes made the scope of the term ...Hou et al. (2004) noted that middle lobopods of P. inermis are longer and sturdier than those at the head and so-called "tail" (Figure 6h).
