Review and Evaluation of Homology Hypotheses in Echinoderm Paleobiology
Av Johnny A. Waters, Jeffrey R. Thompson m. fl.
E-bok, 2023
294 kr
Lägg i varukorg
The extraxial-axial theory (EAT) and universal elemental homology (UEH) are often portrayed as mutually exclusive hypotheses of homology within pentaradiate Echinodermata. EAT describes homology upon the echinoderm bauplan, interpreted through early post-metamorphic growth and growth zones, …

Echinoderms have evolved diverse and disparate morphologies throughout the Phanerozoic. Among them, blastozoans, an extinct group of echinoderms that were an important component of Paleozoic marine ecosystems, are primarily subdivided into groups based on the morphology of respiratory structures. …
