Benthic annelids belonging to the family Syllidae show a distinctive sexual reproduction mode called "stolonization," in which posterior segments are transformed into a reproductive individual-like unit called a "stolon." Megasyllis nipponi...
Developmental plasticity and variability in the formation of egg-spots, a pigmentation ornament in the cichlid Astatotilapia calliptera [0.03%]
发育可塑性及斑马鱼艾美氏小丽鱼(Astatotilapia calliptera)卵点表型变异性的形成机制研究

Bethan Clark et al.
Vertebrate pigmentation patterns are highly diverse, yet we have a limited understanding of how evolutionary changes to genetic, cellular, and developmental mechanisms generate variation. To address this, we examine the formation of a sexua...
Telencephalic eversion in embryos and early larvae of four teleost species [0.03%]

The telencephalon of ray-finned fishes undergoes eversion, which is very different to the evagination that occurs in most other vertebrates. Ventricle morphogenesis is key to build an everted telencephalon. Thus, here we use the apical mark...
Deciphering the origin of developmental stability: The role of intracellular expression variability in evolutionary conservation [0.03%]

Progress in evolutionary developmental biology (evo-devo) has deepened our understanding of how intrinsic properties of embryogenesis, along with natural selection and population genetics, shape phenotypic diversity. A focal point of recent...

Nervous system is one of the key adaptations underlying the evolutionary success of the majority of animal groups. Ctenophores (or comb jellies) are gelatinous marine invertebrates that were probably the first lineage to diverge from the re...
Feeding-structure morphogenesis in "rhabditid" and diplogastrid nematodes is not controlled by a conserved genetic module [0.03%]
“rhabditid”和diplogastrid线虫的取食结构形态发生不受保守遗传模块控制

Disentangling the evolution of the molecular processes and genetic networks that facilitate the emergence of morphological novelties is one of the main objectives in evolutionary developmental biology. Here, we investigated the evolutionary...
The evolution of cnidarian stinging cells supports a Precambrian radiation of animal predators [0.03%]
刺胞动物刺细胞的演化支持前寒武纪动物捕食者的辐射这一观点

Cnidarians-the phylum including sea anemones, corals, jellyfish, and hydroids-are one of the oldest groups of predatory animals. Nearly all cnidarians are carnivores that use stinging cells called cnidocytes to ensnare and/or envenom their ...
A plurality of morphological characters need not equate with phylogenetic accuracy: A rare genomic change refutes the placement of Solifugae and Pseudoscorpiones in Haplocnemata [0.03%]
多个形态特征不等同于系统发育准确性：一个罕见的基因组变化推翻了Solifugae和Pseudoscorpiones在Haplocnemata中的位置

Recent advances in higher-level invertebrate phylogeny have leveraged shared features of genomic architecture to resolve contentious nodes across the tree of life. Yet, the interordinal relationships within Chelicerata have remained recalci...

Larvae represent a distinct life history stage in which animal morphology and behavior contrast strongly to adult organisms. This life history stage is a ubiquitous aspect of animal life cycles, particularly in the marine environment. In ma...

Lissamphibians, represented today by frogs, salamanders, and caecilians, diverged deep in the tetrapod tree of life. Extensive morphological adaptations to disparate lifestyles have made linking extant lissamphibians to one another and to t...
