True New Igkappa Genes in Echinodermata

Evidence of Il2 and Il6 Genes in the Crinoïd: Antedon bifida (Echinodermata)

This report shows for the first time, the evidence of IL6 gene in an Echinodermata, so in an Invertebrate. It recalls also the existence of IL2 gene, we have found also in the Ophuirid: Ophiocomina nigra, the sister of the Asterid: Asterias rubens. All these animals belong to Echinodermata.

Evolutionary history of regeneration in crinoids (Echinodermata).

The fossil record indicates that crinoids have exhibited remarkable regenerative abilities since their origin in the Ordovician, abilities that they likely inherited from stem-group echinoderms. Regeneration in extant and fossil crinoids is recognized by abrupt differences in the size of abutting plates, aberrant branching patterns, and discontinuities in carbon isotopes. While recovery is comm...
