Phylogenetic relationships among extant classes of echinoderms, as inferred from sequences of 18S rDNA, coincide with relationships deduced from the fossil record.

Journal of molecular evolution - 1 Jan 1994

Wada H, Satoh N

Abstract excerpt

In spite of the rich fossil record and multiple descriptions of morphological and embryological characteristics, the origin and subsequent evolution of echinoderms remain highly controversial issues. Using sequence data derived from 18S rDNA, we have investigated the phylogenetic relationships among five extant classes of echinoderms--namely, crinoids, asteroids, ophiuroids, echinoids, and holothurians. Almost...
