Resynthesizing Evolutionary and Developmental Biology

open access: yesDevelopmental 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.

Chromatin remodelling and antisense-mediated up-regulation of the developmental switch gene eud-1 control predatory feeding plasticity

open access: yesNature Communications, 2016
In the nematode Pristionchus pacificus, a developmental switch, the sulfatase eud-1, controls mouth-form plasticity. Here, the authors show that mutations in two conserved histone modifying enzymes mimic the eud-1 phenotype, in part mediated by an ...

Adult Influence on Juvenile Phenotypes by Stage-Specific Pheromone Production

open access: yesiScience, 2018
Summary: Many animal and plant species respond to population density by phenotypic plasticity. To investigate if specific age classes and/or cross-generational signaling affect density-dependent plasticity, we developed a dye-based method to ...

Compression Fractures and Partial Phenotype Rescue With a Low Phosphorus Diet in the Chihuahua Zebrafish Osteogenesis Imperfecta Model

open access: yesFrontiers in Endocrinology, 2022
Osteogenesis imperfecta (OI) is a group of heritable disorders affecting bone and other connective tissues. Dominant OI forms are mainly caused by mutations in collagen type I.

The future of evolutionary developmental biology [PDF]

open access: yesNature, 1999
Combining fields as diverse as comparative embryology, palaeontology, molecular phylogenetics and genome analysis, the new discipline of evolutionary developmental biology aims at explaining how developmental processes and mechanisms become modified during evolution, and how these modifications produce changes in animal morphology and body plans.

More on how and why : a response to commentaries [PDF]

open access: yes, 2013
We are grateful to the commentators for taking the time to respond to our article. Too many interesting and important points have been raised for us to tackle them all in this response, and so in the below we have sought to draw out the major themes ...

Beyond the whole-mount phenotype: high-resolution imaging in fluorescence-based applications on zebrafish

open access: yesBiology Open, 2019
Zebrafish is now widely used in biomedical research as a model for human diseases, but the relevance of the model depends on a rigorous analysis of the phenotypes obtained.

Cells at the Edge: The Dentin–Bone Interface in Zebrafish Teeth

open access: yesFrontiers in Physiology, 2021
Bone-producing osteoblasts and dentin-producing odontoblasts are closely related cell types, a result from their shared evolutionary history in the ancient dermal skeleton.

Evolutionary crossroads in developmental biology: Cnidaria [PDF]

open access: yesDevelopment, 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.

Notch signaling generates the “cut here line” on the cuticle of the puparium in Drosophila melanogaster

open access: yesiScience, 2023
Summary: During a molt or eclosion, insects shed their cuticle, an extracellular matrix made by underlying epidermal cells, by cleavage along a defined line.
