Among vertebrates, ray-finned fishes (Actinopterygii) display the highest diversity in parental care, and their diversification has been hypothesized to be related phylogenetic changes fertilization modes. Using most comprehensive, sex-specific data from 7,600 species of 62 extant orders fishes, we inferred ancestral states transitions among care types caring episodes (i.e., stage offspring development). Our work uncovered 3 novel findings. First, different male-only female-only biparental no care) are common, frequencies these show unusually diverse patterns concerning modes (external, or internal via oviduct, mouth, brood pouch). Second, both oviduct mouth selected for female-biased whereas a pouch is male-biased care. Importantly, without extremely unstable phylogenetically. Third, that egg sexes associated with nest building (which male-biased) fry female-biased). Taken together, aquatic environment, which supports considerable flexibility facilitated parenting behavior, creating evolutionary bases more comprehensive protect semiterrestrial terrestrial environments.

In the highly derived syngnathid fishes (pipefishes, seadragons & seahorses), evolution of sex-role reversed brooding behavior culminated in seahorse lineage's male pregnancy, whose males feature a specialized brood pouch into which females deposit eggs during mating. Then, are intimately engulfed by placenta-like tissue that facilitates gas and nutrient exchange. As fathers immunologically tolerate allogenic embryos, it was suggested pregnancy co-evolved with specific immunological adaptations. Indeed, here we show amino-acid replacement tlx1 transcription factor is associated seahorses' asplenia (loss spleen, an organ central immune system), as confirmed CRISPR-Cas9 experiment using zebrafish. Comparative genomics across phylogeny revealed complexity system gene repertoire decreases parental care intensity increases. The synchronous immunogenetic alterations supports notion tolerance embryo.

Abstract The repeated evolution of the same traits in distantly related groups (convergent evolution) raises a key question evolutionary biology: do genes underpin convergent phenotypes? Here, we explore one such trait, viviparity (live birth), which, qualitative studies suggest, may indeed have evolved via genetic convergence. There are >150 independent origins live birth vertebrates, providing uniquely powerful system to test mechanisms underpinning convergence morphology, physiology, and/or gene recruitment during pregnancy. We compared transcriptomic data from eight vertebrates (lizards, mammals, sharks) that gestate embryos within uterus. Since many previous detected similarities use pregnancy, expected find significant overlap viviparous taxa. However, found no more uterine expression associated with than would expect by chance alone. Each lineage exhibits core set physiological functions. Yet, contrary prevailing assumptions about this none differentially expressed all lineages, or even amniote lineages. Therefore, across different been recruited support morphological and changes required for successful conclude redundancies function enabled through genomic “toolboxes”, which constrained ancestries each lineage.

Seahorses, pipefishes, and seadragons are fishes from the family Syngnathidae that have evolved extraordinary traits including male pregnancy, elongated snouts, loss of teeth, dermal bony armor. The developmental genetic cellular changes led to evolution these largely unknown. Recent syngnathid genome assemblies revealed suggestive gene content differences provided opportunity for detailed analyses. We created a single-cell RNA sequencing atlas Gulf pipefish embryos understand basis four traits: derived head shape, toothlessness, armor, pregnancy. completed marker analyses, built networks, examined spatial expression select genes. identified osteochondrogenic mesenchymal cells in elongating face express regulatory genes bmp4, sfrp1a , prdm16 . found no evidence tooth primordia cells, we observed re-deployment osteoblast networks developing Finally, epidermal expressed nutrient processing environmental sensing genes, potentially relevant brooding environment. evolutionary innovations composed recognizable cell types, suggesting features originate within existing networks. Future work addressing across multiple stages species is essential understanding how novelties fish evolved.
