In several lineages that independently evolved terrestrial eggs, and retained aquatic tadpoles, embryos accelerate hatching to escape from drying eggs, entering the water earlier and less developed. However, the cues that stimulate drying-induced early hatching are unknown. Ammonia is a toxic, water-soluble metabolic waste that accumulates within eggs as embryos develop and concentrates as eggs dehydrate. Thus, increasing ammonia concentration may be a direct threat to embryos in drying eggs. We hypothesized that it could serve as a cue, stimulating embryos to hatch and escape. The embryos of red-eyed treefrogs, <i>Agalychnis callidryas</i>, hatch early to escape from many threats, including dehydration, and are known to use mechanosensory, hypoxia, and light cues. To test if they also use high ammonia as a cue to hatch, we exposed stage-matched pairs of hatching-competent, well-hydrated sibling embryos to ammonia and control solutions in shallow water baths and recorded their behavior. Control embryos remained unhatched while ammonia-exposed embryos showed a rapid, strong hatching response; 95% hatched, on average in under 15 min. This demonstrates that elevated ammonia can serve as a hatching cue for <i>A. callidryas</i> embryos. This finding is a key step in understanding the mechanisms that enable terrestrial frog embryos to escape from egg drying, opening new possibilities for integrative and comparative studies on this growing threat.</p>","PeriodicalId":15682,"journal":{"name":"Journal of experimental zoology.

Taylor, now faculty at the University of Victoria, Canada, and Walter Salzburger, now faculty at the University of Basel, Switzerland. For my doctoral work, I joined Manfred Schartl and Jean-Nicolas Volff at the University of Würzburg, also in Germany, studying the functional genetic impacts of whole genome duplications on the evolution of vertebrate pigmentation. For my postdoc, I worked in the group of John H. Postlethwait at the University of Oregon in Eugene. John's group had just started to use spotted gar as a genomic outgroup to the teleost fishes and the teleost genome duplication. There, I began developing spotted gar as a developmental and functional genomic model system for vertebrate biology and EvoDevo – work that continues in my laboratory at Michigan State University.&lt;/p&gt;&lt;p&gt;I grew up in provincial Germany as the son of a high school chemistry and physics teacher and a pharmaceutical technician, so I was exposed to the natural sciences early on. Starting in elementary school, I developed a passion for reading about dinosaurs and prehistoric people, years before &lt;i&gt;Jurassic Park&lt;/i&gt; made paleontology cool. Thus, although I didn't know the term then, I had an early appreciation for macroevolution. In high school, I kept all kinds of aquarium fishes (can you ever have too many tanks?), while reading about Darwin's &lt;i&gt;Voyage of the Beagle&lt;/i&gt;, evolution, and genetics. This fascination kept going and was a reason I chose the University of Konstanz for undergraduate studies because of its strong curricular focus on molecular biology. Working as an undergraduate researcher in the Meyer Lab and being surrounded by an international crew of world-class molecular evolutionary biologists around me – who even used fish models to answer big questions about the deep evolutionary history of vertebrates – was immensely thrilling. Comparing sequences from diverse organisms and reconstructing their evolutionary change across phylogenies, I could practically look back in time! I knew I had found my path. However, sequencing DNA and analyzing genetic information on the computer was not enough for me. Fondly remembering my childhood fish breeding projects and the beauty of watching fish embryos grow, I successively added developmental biology to my research portfolio. The name of my research group, the &lt;i&gt;Fish Evo Devo Geno Lab&lt;/i&gt;, reflects this multipronged approach.&lt;/p&gt;&lt;p&gt;Observing the elegance of developmental processes in many different fish species is my happy place.

A recent symposium held at the 5th Argentinean Meeting on Evolutionary Biology (RABE V) showcased a vibrant Evo-Devo community and the diversity of its research endeavors. The symposium included 3 plenary talks, 3 short talks, and 12 posters, and spanned a range of organisms and approaches. Interestingly, the symposium highlighted a prevalence of “top-down” Evo-Devo studies in the region, where researchers first analyze existing diversity and then propose potential developmental mechanisms. This approach, driven in part by financial constraints and the region's historical focus on natural history, presents a unique opportunity to bridge disciplines like comparative biology, paleontology, and botany. The symposium's success underscores the vital role of Evo-Devo in Latin America, not only for advancing our understanding of evolution but also for providing valuable tools to conserve and manage the region's irreplaceable biodiversity. As Evo-Devo continues to grow in Latin America, fostering collaboration and knowledge exchange within the region and beyond will be crucial for realizing the full potential of this transformative field.</p>","PeriodicalId":15682,"journal":{"name":"Journal of experimental zoology.

Other domesticates also show distinct changes to their vocal output: domestic cats retain meows, a distinctly subadult trait in wildcats. Such differences in acoustic output are well-known, but the causal mechanisms remain little-studied. Potential links between domestication and vocal output are intriguing for multiple reasons, and offer a unique opportunity to explore a prominent hypothesis in domestication research: the neural crest/domestication syndrome hypothesis. This hypothesis suggests that in the early stages of domestication, selection for tame individuals decreased neural crest cell (NCCs) proliferation and migration, which led to a downregulation of the sympathetic arousal system, and hence reduced fear and reactive aggression. NCCs are a transitory stem cell population crucial during embryonic development that tie to diverse tissue types and organ systems. One of these neural-crest derived systems is the larynx, the main vocal source in mammals. We argue that this connection between NCCs and the larynx provides a powerful test of the predictions of the neural crest/domestication syndrome hypothesis, discriminating its predictions from those of other current hypotheses concerning domestication.</p>","PeriodicalId":15682,"journal":{"name":"Journal of experimental zoology.

We contend that these controversies stem from a fundamental disagreement about what constitutes a well-defined biological trait, a problem that has received insufficient attention despite its recognized importance in biology. In this paper, we leverage paleoanthropological research on the human chin to investigate the general issue of character or trait identification. First, we examine four accounts of the human chin from the existing literature: the mandibular differential growth byproduct, the bony prominence, the inverted T-relief, and the symphyseal angle. We then generalize from these accounts and propose a three-stage framework for the process of character identification: description, detection, and justification. We use this framework to reinterpret the four accounts, elucidating key points of contention surrounding the chin as well as other morphological characters. We show that debates over the chin carry broad and important biological implications that extend beyond this trait and that are not mere semantic issues of definition.</p>","PeriodicalId":15682,"journal":{"name":"Journal of experimental zoology.

In invertebrate, methylated cytosine generally located on specific genomic elements (e.g., gene bodies and silenced repetitive elements) to show a “mosaic” pattern. While in jawed vertebrate (teleost and tetrapod), highly methylated cytosine located genome-wide but only absence at regulatory regions (e.g., promoter and enhancer). Many studies imply that the evolution of DNA methylation reprogramming may have helped the transition from invertebrates to jawed vertebrates, but the detail remains largely elusive. In this study, we used the whole-genome bisulfite-sequencing technology to investigate the genome-wide methylation in three tissues (heart, muscle, and sperm) from the sea lamprey, an extant agnathan (jawless) vertebrate. Strikingly, we found that the methylation level of the sea lamprey is very similar to that in sea urchin (a deuterostome) and sea squirt (a chordate) invertebrates. In sum, the global pattern in sea lamprey is intermediate methylation level (around 30%), that is higher than methylation level in the genomes of pre-bilaterians and protostomes (1%−10%), but lower than methylation level appeared in jawed vertebrates (around 70%, teleost and tetrapod).
