SUMMARY Evolutionary biologists studying life history variation have used echinoderms in experimental, laboratory, and field studies of life history evolution. This focus on echinoderms grew originally from the tradition of comparative embryology, in which echinoderms were central. The tools for obtaining and manipulating echinoderm gametes and larvae were taken directly from comparative embryological research. In addition, the comparative embryologists employed a diverse array of echinoderms…

Applying the perspective of organizational homology to the experimental system of congeneric echinoids has led to a new hypothesis concerning the ectoderm evolution in these species, instantiates a theoretical principle concerning the origin of developmental modules, 'integration'.

Many evolutionary modifications in development and life history derive from changes in embryonic gene expression. However, the genetic variation affecting gene expression in natural populations is

THYROID HORMONE-LIKE FUNCTION IN ECHINOIDS: A MODULAR SIGNALING SYSTEM COOPTED FOR LARVAL DEVELOPMENT AND CRITICAL FOR LIFE HISTORY EVOLUTION

It is argued that hormones are frequently involved in the coordination of life history transitions (LHTs) and their evolution (LHE) and promoted the usefulness of a comparative, non-model system approach towards understanding how hormones function and guide development and evolution.

The hologenome concept of evolution after 10 years

It is argued that rapid changes in the microbiome genome could allow holobionts to Adapt and survive under changing environmental conditions thus providing the time necessary for the host genome to adapt and evolve.

A comparative analysis of egg provisioning using mass spectrometry during rapid life history evolution in sea urchins

How mass spectrometry can enrich the understanding of life history evolution and organismal diversity by identifying specific molecules associated with distinct life history strategies and prompt new hypotheses about how and why these adaptations evolve is demonstrated.

Long-term storage lipids and developmental evolution in echinoderms

Energetic lipids in the small eggs of echinoderms with feeding larvae are primarily TAG, a class of short-term storage lipids, and DAGE, which is metabolized more slowly than TAG, dominates the large eggs of ophiuroid species with non-feeding larvae.

Fuels for development: evolution of maternal provisioning in asterinid sea stars

Two major oogenic modifications associated with the evolution of lecithotrophic development are identified: a reduction in protein deposition that probably reflects the reduced structural requirements of nonfeeding larvae, and an increase in deposition of a single class of energetic lipid, triglyceride (TG).

Gene expression patterns in a novel animal appendage: the sea urchin pluteus arm

The expression of a larval arm‐associated ectoderm gene tetraspanin and two new PMC markers, advillin and carbonic anhydrase, are reported, suggesting that pluteus arms are novel larval organs, distinguishable from the processes of skeletogenesis per se.

Something for nothing? Reconstruction of ancestral character states in asterinid sea star development

Improved analytical methods are applied to the inference of ancestral states for ecological and morphological characters in the reproduction and larval development of asterinid sea stars and it is shown that the new methods might generally offer some independent insight into choice of a model of character evolution, but that the quantitative features of the model have an important effect on the results.

POPULATION GENETIC CONSEQUENCES OF DEVELOPMENTAL EVOLUTION IN SEA URCHINS (GENUS HELIOCIDARIS)

A pattern of mitochondrial variation suggests that these population differences have arisen recently and may reflect the historical interplay between the restricted dispersal capabilities of H. erythrogramma and the climatic and geological changes associated with Pleistocene Ice Ages.

Oogenic strategies in the evolution of development in Patiriella (Echinodermata: Asteroidea)

Comparison of protein profiles, histochemistry and ultrastructure of the eggs of Patiriella indicated that the major changes underlying acquisition of a large egg involved enhanced deposition of lipid in some species and an increase in yolk reserves in others.

Feeding and Nonfeeding Larval Development and Life-History Evolution in Marine Invertebrates

Many marine invertebrates have elaborate feeding larval forms whereas others, sometimes within the same taxon, have more direct development, and questions about the evolution and consequences of the life histories of these forms are raised.

It is demonstrated that sea urchin Wnt‐5 transcripts are specifically detected by in situ hybridization in discrete embryonic, larval, and developing adult tissues and processes, suggesting that Wnt-5 function(s) have been conserved in sea ittee development.
