A stem-group cnidarian described from the mid-Cambrian of China and its significance for cnidarian evolution

Palaeontological data of extinct groups often sheds light on the evolutionary sequences leading to extant groups, but has failed to resolve the basal metazoan phylogeny including the origin of the Cnidaria. Here we report the occurrence of a stem-group cnidarian, Cambroctoconus orientalis gen. et sp. nov., from the mid-Cambrian of China, which is a colonial organism with calcareous octagonal co...

Cnidarian milestones in metazoan evolution.

Cnidarians display most of the characters considered as milestones of metazoan evolution. Whereas a tissue-level organization was probably already present in the multicellular common ancestor of all animals, the Urmetazoa, the emergence of important animal features such as bilateral symmetry, triploblasty, a polarized nervous system, sense organs (eyes, statocysts), and a (chitinous or calcium-...

Cladistic analysis of Medusozoa and cnidarian evolution

A cladistic analysis of 87 morphological and life history characters of medusozoan cnidarians, rooted with Anthozoa, results in the phylogenetic hypothesis (Anthozoa (Hydrozoa (Scyphozoa (Staurozoa, Cubozoa)))). Staurozoa is a new class of Cnidaria consisting of Stauromedusae and the fossil group Conulatae. Scyphozoa is redefined as including those medusozoans characterized by strobilation and ...

Phylogeny of Medusozoa and the evolution of cnidarian life cycles

The considerable morphological disparity present within Cnidaria is evidenced by delicate siphonophores, massive medusae and corals, feathery hydroids, interstitial polyps and box jellies possessing complex eyes. Despite this diversity, these relatively simple metazoans are united in possessing nematocysts, most probably as a result of common ancestry. Corroborating evidence that cnidarians are...

Horizontal gene transfer and the evolution of cnidarian stinging cells

for detecting the crowding of texture are both at play. Disentangling the two will be an interesting challenge. One promising line, as Durgin [8] suggests, will be to look for dissociations between number and texture perception. Manuela Piazza, Stanislas Dehaene and Marco Zorzi (personal communication) have shown that dyscalculic individuals have higher Weber fraction for number discrimination ...
