【 摘 要 】

Vetulicolians are an enigmatic group of Cambrian organisms that have been affiliated at various times with arthropods, lobopodians, kinorhynchs and deuterostomes. New evidence on the structure of the lateral pores of vetulicolians published in BMC Biology strengthens the view that they may be total group deuterostomes, but unfortunately sheds no new light on early deuterostome evolution.See research article http://www.biomedcentral.com/1741-7007/10/81
