The echinoderms are an ideal group to understand evolution from a holistic, interdisciplinary framework. genetic regulatory networks underpinning development in some of the best known for any model group. Additionally, have excellent fossil record, elucidating detail evolutionary changes morphological evolution. In this Element, discussed as molecular palaeobiological studies, integrating what is their development, genomes, and record. Together, these insights shed light on vast biodiversity echinoderms, animal kingdom more generally.

Organisms interacting with echinoids are common and produce diverse traces that often distinctive can be preserved in the fossil record. Thus, provide a wealth of information regarding role biotic interactions as drivers ecological morphological adaptations over macroevolutionary timescales. Studies documenting resulting have become more numerous. This Element reviews ecologies skeletal trace-producing on Modern ecosystems recognition those biogenic The authors explore diversification trends Meso-Cenozoic echinoid clades associated predator parasite groups context selective pressures brought about by evolution these interactions.

A Review and Evaluation of Homology Hypotheses in Echinoderm Paleobiology DOI Creative Commons

The extraxial-axial theory (EAT) and universal elemental homology (UEH) are often portrayed as mutually exclusive hypotheses of within pentaradiate Echinodermata. EAT describes upon the echinoderm bauplan, interpreted through early post-metamorphic growth zones, dividing it into axial regions generally associated with elements ambulacral system extraxial that not. UEH detailed construction skeleton, homologous plates plate series based on symmetry, growth, function. These not in conflict; latter is rooted refinement former. Some interpretive differences arise because many morphologies described from eleutherozoan development difficult to reconcile Paleozoic forms. Conversely, for taxa by UEH, such peristomial border plates, absent eleutherozoans. This Element recommends these two be used together generate a better understanding across
