Reproductive isolation is the key attribute of biological species and establishment of the reproductive barriers is an essential event for speciation. Among the mechanisms of reproductive isolation, gamete incompatibility due to the variability of gamete interaction proteins may drive fast divergence even in sympatry. However, the number of available models to study this phenomenon is limited. In case of internally fertilized invertebrates, models to study gamete incompatibility and sperm competition mechanisms are restricted to a single taxon: insects...

Evodevo is concerned with understanding how phenotypes develop and evolve, how organismal diversity is generated and maintained, and how evolutionary innovations originate. The second Pan-American Society for Evolutionary Developmental Biology (PASEDB) meeting in Calgary, Canada, showcased a great variety of species and study systems, and a variety of approaches to address these questions. Although there were, like at the first PASEDB meeting, many developmental genetic and genomic studies, much of the work moved beyond comparative developmental genetics toward more integrative studies that seek explanations at different levels of the organismal hierarchy...

In oocytes, RNA localization has critical implications, as assembly of proteins in particular subcellular domains is crucial to embryo development. The distribution of mRNA molecules can identify and characterize localized transcripts. The goal of this study was to clarify the origin of primordial germ cells in the oocyte body plan and to reveal the generation of cell lineages by localized RNAs. The distribution of 12 selected mRNAs in sterlet Acipenser ruthenus oocytes was investigated by qPCR tomography and compared with known patterns of mRNA localization in Xenopus laevis...

The evolution of viviparity requires eggshell thinning to bring together the maternal uterus and extraembryonic membranes to form placentae for physiological exchanges. Eggshell thinning likely involves reduced activity of the uterine glands that secrete it. We tested these hypotheses by comparing the uterine and eggshell structure and histochemistry among oviparous and viviparous water snakes (Helicops) using phylogenetic methods. Eggshell thinning occurred convergently in all three origins of viviparity in Helicops and was accomplished by the loss of the mineral layer and thinning of the shell membrane...

The Sox9 gene is important for determining sex in vertebrates, as well as for maintaining testis morphology and fertility during adult life. In the same way, Vasa is an important gene for the maintenance of the germinal lineage and has been highly conserved throughout evolution, as it is expressed in germ cells of both vertebrates and invertebrates. In the particular case of crocodiles, the expression of Sox9 during gonadal morphogenesis and in the testes of 3-month-old Alligator mississippiensis has been studied...

Limb development in salamanders is unique among tetrapods in significant ways. Not only can salamanders regenerate lost limbs repeatedly and throughout their lives, but also the preaxial zeugopodial element and digits form before the postaxial ones and, hence, with a reversed polarity compared to all other tetrapods. Moreover, in salamanders with free-swimming larval stages, as exemplified by the axolotl (Ambystoma mexicanum), each digit buds independently, instead of undergoing a paddle stage. Here, we report gene expression patterns of Hoxa and d clusters, and other crucial transcription factors during axolotl limb development...

Joeri Witteveen
A popular narrative about the history of modern biology has it that Ernst Mayr introduced the distinction between "typological thinking" and "population thinking" to mark a contrast between a metaphysically problematic and a promising foundation for (evolutionary) biology, respectively. This narrative sometimes continues with the observation that, since the late-20th century, typological concepts have been making a comeback in biology, primarily in the context of evolutionary developmental biology...

The acquisition of genome sequences from a wide range of insects and other arthropods has revealed a broad positive correlation between the complexity of their chemical ecology and the size of their chemosensory gene repertoire. The German cockroach Blattella germanica is an extreme omnivore and has the largest chemosensory gene repertoire known for an arthropod, exceeding even the highly polyphagous spider mite Tetranychus urticae. While the Odorant Receptor family is not particularly large, with 123 genes potentially encoding 134 receptors (105 intact), the Gustatory Receptor family is greatly expanded to 431 genes potentially encoding 545 receptors (483 intact), the largest known for insects and second only to the spider mite...

In human females, direct or indirect stimulation of the clitoris plays a central role in reaching orgasm. A majority of women report that penetrative coitus alone is insufficient for triggering orgasm, puzzling researchers who expect orgasm to be an outcome of procreative intercourse. In the present paper, we turn our attention to the evolutionary role that such unreliability of orgasm at coitus might have played in human evolution. We emphasize that we do not thereby attempt an explanation of its origin, but its potential evolutionary effect...

Ants evolved about 140 million years ago and have diversified into more than 15,000 species with tremendous ecological and morphological diversity, yet evolution of the gene regulatory networks (GRNs) underlying this diversification remains poorly understood. Wing polyphenism, the ability of a single genome to produce either winged or wingless castes during development in response to environmental cues, is a nearly universal feature of ants. The underlying wing GRN is evolutionarily labile in worker castes of phylogenetically derived species: it is conserved in winged castes but interrupted at different points in wingless castes of different species...

The postembryonic development of amphibians has been characterized as divided into three predominant periods, hereafter named primary developmental stages: premetamorphosis (PreM), prometamorphosis (ProM), metamorphic climax (Meta), and completion of metamorphosis (PostM), largely based on examination of anuran development. Here, we categorized the postembryonic development of larvae of a poisonous fire salamander (Salamandra salamandra) by integrating morphology and gene expression (transcriptomic) data. Morphological analysis revealed three distinct clusters suggestive of PreM, ProM, and Meta, which were confirmed in parallel by microarray-derived gene expression analysis...

We report the complete sequence analysis of the entire complement of eight typical homeobox (Hox) genes (Lab, Pb, Dfd, Scr, Antp, Ubx, Abd-A, and Abd-B) and two other genes (Hox3 and Ftz) in a 324.6-kb region in the water flea Daphnia magna. In the cluster of D. magna Hox genes, we found one long interspersed nuclear element (LINE)/R2-NeSL between Ubx and Abd-A that was not present in Daphnia pulex Hox genes. In basal expression of Hox genes at different developmental stages, biothorax complex genes (Ubx, Abd-A, and Abd-B) and some antennapedia complex genes (Lab, Scr, Antp) were moderately expressed, but the Hox3 gene was barely expressed...

In this study, IMO-TaqI satDNA, previously isolated in several species of Lacertidae, was isolated and characterized from four species of the genus Lacerta and three of the genus Timon. The aim was to gain further insights into the evolutionary dynamics of this satDNA, its occurrence among lacertids and to understand if it plays any role in sex chromosome evolution in these seven species. The results here obtained highlighted the presence of this repetitive element in the genome of all the species investigated, thus indicating that IMO-TaqI satDNA is evolutionary conserved among a wide variety of lacertids...

After the inaugural Pan-American-Evo-Devo meeting (2015, Berkeley), I showed how major concerns about evo-devo (Evolutionary Developmental Biology) research were demonstrated by a simple, non-biased quantitative analysis of the titles/abstracts of that meeting's talks. Here, I apply the same methodology to the titles/abstracts of the recent Pan-American-Evo-Devo meeting (2017, Calgary). The aim is to evaluate if the concerns raised by me in that paper and by other authors have been addressed and/or if there are other types of differences between the two meetings that may reflect trends within the field of evo-devo...

The genetic regulation of anterior-posterior segment pattern development has been elucidated in detail for Drosophila, but it is not canonical for insects. A surprising diversity of regulatory mechanisms is being uncovered not only between insect orders, but also within the order of the Diptera. The question is whether the same diversity of regulatory mechanisms exists within other insect orders. I show that anterior puncture of the egg of the pea beetle Callosobruchus maculatus submerged in RNase can induce double abdomen development suggesting a role for maternal mRNA...

The strictly maternal inheritance (SMI) is a pattern of mitochondrial inheritance observed across the whole animal kingdom. However, some interesting exceptions are known for the class Bivalvia, in which several species show an unusual pattern called doubly uniparental inheritance (DUI) whose outcome is a heteroplasmic pool of mtDNA in males. Even if DUI has been studied for long, its molecular basis has not been established yet. The aim of this work is to select classes of proteins known to be involved in the maintenance of SMI and to compare their features in two clam species differing for their mitochondrial inheritance mechanism, that is, the SMI species Ruditapes decussatus and the DUI species Ruditapes philippinarum...

Reconciling different underlying ontologies and explanatory contexts has been one of the main challenges and impediments for theory integration in biology. Here, we analyze the challenge of developing an inclusive and integrative theory of phenotypic evolution as an example for the broader challenge of developing a theory of theory integration within the life sciences and suggest a number of necessary formal steps toward the resolution of often incompatible (hidden) assumptions. Theory integration in biology requires a better formal understanding of the structure of biological theories The strategy for integrating theories crucially depends on the relationships of the underlying ontologies...

Relaxin (RLN) and insulin (INSL)-like peptides are member of the INSL/RLN superfamily, which are encoded by seven genes in humans and can activate the G-protein coupled receptor RXFP 1-4. These peptides evolved from a common ancestor, RLN3-like gene. Two rounds of whole genome duplication (WGD) in early vertebrate evolution, together with an additional WGD in the teleost lineage, caused an expansion of RLN genes set in the genome of Danio rerio. In particular, six RLN genes are present: a single copy of rln and insl3 genes, and two paralogs for the rln3 gene (rln3a and rln3b), and the insl5 gene (insl5a and insl5b)...

The transfer of egg white into the yolk and consumption of yolk proteins by the embryo are largely unexplored in the pigeon Columba livia domestica. Here, we investigated the route of egg white transfer as well as the degradation and uptake of yolk proteins by the pigeon embryo. Initially, we tested the electrophoretic patterns of proteins in different egg compartments throughout development. Then, we used lysozyme as a reference protein to follow the egg white transfer, and we measured its activity using Micrococcus lysodeikticus as a substrate...
