Guest Anax Posted September 6, 2004 Posted September 6, 2004 Is anyone familiar with Richard Jeffries calcichordate theory of chordate origins (linking chordates and echinoderms through the unusual mitrate and cornute echinoderms)? I'm curious what the current thought is on this theory - whether cornutes and mitrates are believed to be part of a common chordate/ echinoderm lineage or whether they are thought to have independantly evolved some of their more chordate-like features.
