Evolutionary crossroads in developmental biology: Cnidaria [PDF]
Development, 2011 There is growing interest in the use of cnidarians (corals, sea anemones, jellyfish and hydroids) to investigate the evolution of key aspects of animal development, such as the formation of the third germ layer (mesoderm), the nervous system and the generation of bilaterality.

Resynthesizing Evolutionary and Developmental Biology
Developmental Biology, 1996 A new and more robust evolutionary synthesis is emerging that attempts to explain macroevolution as well as microevolutionary events. This new synthesis emphasizes three morphological areas of biology that had been marginalized by the Modern Synthesis of genetics and evolution: embryology, macroevolution, and homology.

Evolutionary crossroads in developmental biology [PDF]
Development, 2012 Currently, most developmental biologists work on one or more of a relatively small number of experimental systems, such as Arabidopsis thaliana, Drosophila melanogaster (fruit fly), Xenopus laevis (frog), Caenorhabditis elegans (nematode), Danio rerio (zebrafish) and Mus musculus (mouse), and ...

Beyond Arabidopsis. Translational Biology Meets Evolutionary Developmental Biology [PDF]
Plant Physiology, 2004 Abstract Developmental processes shape plant morphologies, which constitute important adaptive traits selected for during evolution. Identifying the genes that act in developmental pathways and determining how they are modified during evolution is the focus of the field of evolutionary developmental biology, or evo-devo.

Evolutionary origin of type IV classical cadherins in arthropods
BMC Evolutionary Biology, 2017 Background Classical cadherins are a metazoan-specific family of homophilic cell-cell adhesion molecules that regulate morphogenesis. Type I and type IV cadherins in this family function at adherens junctions in the major epithelial tissues of ...

Developmental dynamics is revealed in the early Cambrian arthropod Chuandianella ovata
iScience, 2022 Summary: Segmentation and tagmatization have contributed to the preeminent success of arthropods since their first appearance in the Cambrian. However, the exact mechanism of segmentogenesis is still insufficiently known in living and extinct groups ...

Protocol for the rapid intravenous in ovo injection of developing amniote embryos
STAR Protocols, 2023 Summary: We present a technique for precise drug delivery into the vascular system of developing amniote embryos via injection into chorioallantoic veins underlying the eggshell membrane.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

The common house spider Parasteatoda tepidariorum
EvoDevo, 2020 The common house spider Parasteatoda tepidariorum, belonging to the Chelicerata in the phylum Arthropoda, has emerged as an experimental system for studying mechanisms of development from an evolutionary standpoint.
