The origin of morphological and ecological novelties is a long-standing problem in evolutionary biology.Understanding these processes requires investigation from both the development and evolution standpoints,which promotes a new research field called"evolutionary developmental biology"(evo-devo).The fundamental mechanism for the origin of a novel structure may involve heterotopy,heterochrony,ectopic expression,or loss of an existing regulatory factor.Accordingly,the morphological and ecological traits controlled by the regulatory genes may be gained,lost,or regained during evolution.Floral morphological novelties,for example,include homeotic alterations(related to organ identity),symmetric diversity,and changes in the size and morphology of the floral organs.These gains and losses can potentially arise through modification of the existing regulatory networks.Here,we review current knowledge concerning the origin of novel floral structures,such as"evolutionary homeotic mutated flowers",floral symmetry in various plant species,and inflated calyx syndrome(ICS)within Solanaceae.Functional evo-devo of the morphological novelties is a central theme of plant evolutionary biology.In addition,the discussion is extended to consider agronomic or domestication-related traits,including the type,size,and morphology of fruits(berries),within Solanaceae. 展开更多

The inverted retina is a basic characteristic of the vertebrate eye.This implies that vertebrates must have a common ancestor with an inverted retina.Of the two groups of chordates,cephalochordates have an inverted retina and urochordates a direct retina.Surprisingly,recent genetics studies favor urochordates as the closest ancestor to vertebrates.The evolution of increasingly complex organs such as the eye implies not only tissular but also structural modifications at the organ level.How these configurational modifications give rise to a functional eye at any step is still subject to debate and speculation.Here we propose an orderly sequence of phylogenetic events that closely follows the sequence of developmental eye formation in extant vertebrates.The progressive structural complexity has been clearly recorded during vertebrate development at the period of organogenesis.Matching the chain of increasing eye complexity in Mollusca that leads to the bicameral eye of the octopus and the developmental sequence in vertebrates,we delineate the parallel evolution of the two-chambered eye of vertebrates starting with an early ectodermal eye.This sequence allows for some interesting predictions regarding the eyes of not preserved intermediary species.The clue to understanding the inverted retina of vertebrates and the similarity between the sequence followed by Mollusca and chordates is the notion that the eye in both cases is an ectodermal structure,in contrast to an exclusively(de novo)neuroectodermal origin in the eye of vertebrates.This analysis places cephalochordates as the closest branch to vertebrates contrary to urochordates,claimed as a closer branch by some researchers that base their proposals in a genetic analysis. 展开更多

Aim was to gather relevant knowledge in evolution and development to find a rational explanation for the intricate and elaborate anatomy of the nose. According to classic embryology, the philtrum of the upper lip, nasal dorsum, septum and primary palate develop from the intermaxillary process, and the lateral walls of the nasal pyramid from the lateral nasal processes. The palatal shelves, which are outgrowths of the maxillary processes, form the secondary palate. The median nasal septum develops inferiorly from the roof of the nasal cavity. These valuable embryologic data do not explain the complex intricacy of the many anatomical structures comprising the nose. The evo-devo theory offers a rational explanation to this complex anatomy. Phylogenically, the nose develops as an olfactory organ in fish before becoming respiratory in tetrapods. During development, infolding of the olfactory placodes occurs, bringing the medial olfactory processes to form the septolateral cartilage while the lateral olfactory processes form the alar cartilages. The olfactory fascia units these cartilages to the olfactory mucosa, that stays separated from brain by the cartilaginous olfactory capsule(the ethmoid bone forerunner). Phylogenically, the respiratory nose develops between mouth and olfactory nose by rearrangement of the dermal bones of the secondary palate, which appears in early tetrapods. During development, the palatal shelves develop into the palatine processes of the maxillary bones, and with the vomer, palatine, pterygoid and inferior turbinate bones form the walls of the nasal cavity after regression of the transverse lamina. Applying the evolutionary developmental biology(evo-devo) discipline on our present knowledge of development, anatomy and physiology of the nose, significantly expands and places this knowledge in proper perspective. The clinicopathologies of nasal polyposis, for example, occurs specifically in the ethmoid labyrinth or, woodworker's adenocarcinomas, occurring only in the olfactory cleft can now be explained by employing the evo-devo approach. A full understanding of the evo-devo discipline, as it pertains to head and neck anatomy, has profound implications to the otolaryngologist empowering his skills and abilities, and ultimately translating in improving surgical outcomes and maximizing patient care. 展开更多

The spatial and temporal organization of the genome—collectively termed the 4D genome—is pivotal for regulating gene expression,maintaining genome stability,and guiding development.The convergence of chromosome conformation capture technologies,super-resolution microscopy,and single-cell epigenomics has transformed our understanding of chromatin structure and function.Despite these advances,critical gaps remain,particularly,in integrating multi-scale data,interpreting dynamic cellular states,and bridging evolutionary and developmental processes.This critical review synthesizes recent findings and identifies three key conceptual pitfalls:scale transformation,temporal causality,and plasticity in evolutionarydevelopmental dynamics.I also outline emerging methodologies and theoretical frameworks aimed at overcoming these challenges and propose directions for future research to achieve a unified and predictive model of a functional genome. 展开更多

The flower is an evolutionary innovation in angiosperms that drives the evolution of biodiversity.The carpel is integral to a flower and develops into fruits after fertilization,while the perianth,consisting of the calyx and corolla,is decorative to facilitate pollination and protect the internal organs,including the carpels and stamens.Therefore,the nature of flower origin is carpel and stamen origin,which represents one of the greatest and fundamental unresolved issues in plant evolutionary biology.Here,we briefly summarize the main progress and key genes identified for understanding floral development,focusing on the origin and development of the carpels.Floral ABC models have played pioneering roles in elucidating flower development,but remain insufficient for resolving flower and carpel origin.The genetic basis for carpel origin and subsequent diversification leading to fruit diversity also remains elusive.Based on current research progress and technological advances,simplified floral models and integrative evolutionary-developmental(evodevo)strategies are proposed for elucidating the genetics of carpel origin and fruit evolution.Stepwise birth of a few master regulatory genes and subsequent functional diversification might play a pivotal role in these evolutionary processes.Among the identified transcription factors,AGAMOUS(AG)and CRABS CLAW(CRC)may be the two core regulatory genes for carpel origin as they determine carpel organ identity,determinacy,and functionality.Therefore,a comparative identification of their protein-protein interactions and downstream target genes between flowering and non-flowering plants from an evo-devo perspective may be primary projects for elucidating carpel origin and development. 展开更多

Recent advances have deepened our understanding of the evolutionary and developmental origins of feather branching architectures.However,the internal tissue differentiation within these branches has received limited attention.This study examined eight fossilized feathers preserved in early Late Cretaceous Burmese amber,characterized by barb rami composed entirely of cortical tissue with no internal medulla.Based on barb rami morphology,the feathers were categorized into three distinct morphotypes.Comparative analysis with feather development in extant chickens suggested minimal tissue differentiation in these early feathers.Functional simulations further revealed that modern barb rami configurations provide greater aerodynamic stability than medulla-free early feathers under most conditions,highlighting flexural stiffness as a key factor in the evolution of feather branches.The presence of medullafree barb rami suggests that although the three-level hierarchical branching pattern characteristic of modern feathers had emerged by the Jurassic,tissue differentiation within feather branches remained developmentally unstable during the Late Cretaceous.This instability likely contributed to the structural variability of early feathers,enabling morphologies that no longer persist in modern birds. 展开更多

Angiosperms evolved a great diversity of ways to display their flowers for reproductive success by variation in floral color,size,shape,scent,arrangements,and flowering time.The various innovations in floral forms and the aggregation of flowers into different kinds of inflorescences can drive new ecological adaptations,speciation,and angiosperm diversification.Evolutionary developmental biology(evo-devo)seeks to uncover the developmental and genetic basis underlying morphological diversification.Advances in the developmental genetics of floral display have provided a foundation for insights into the genetic basis of floral and inflorescence evolution.A number of regulatory genes controlling floral and inflorescence development have been identified in model plants(e.g.,Arabidopsis thaliana,Antirrhinum majus)using forward genetics and conserved functions of many of these genes across diverse non-model species have been revealed by reverse genetics.Gene-regulatory networks that mediated the developmental progresses of floral and inflorescence development have also been established in some plant species.Meanwhile,phylogeny-based comparative analysis of morphological and genetic character has enabled the identification of key evolutionary events that lead to morphological complexity and diversification.Here we review the recent progress on evo-devo studies of floral display including floral symmetry,petal fusion,floral color,floral scent,and inflorescences.We also review the molecular genetic approaches applied to plant evo-devo studies and highlight the future directions of evo-devo. 展开更多

After more than one hundred fifty years of the publication of On the Origin of Species by Darwin, scientists are still arguing on the relative importance of mutation and natural selection, on the driving force of organismal evolution, on microevo- lution and macroevolution, etc. Such periodically repeated debates appeared to have introduced more chaos than musings. What happened and why？ Have we really considered our views, opinions and arguments under the big picture of evolution before pos- ing the questions？ Or are we talking past each other？ We do need some reflections. While we believe that the current evolutionary theory is doing fine, perhaps a refinement or re-encapsulation of its knowledge framework can help promote a better understanding of the evolutionary science as a whole and blow offthe mist over the big picture [Current Zoology 61 （1）： 217-220, 2015 ]. 展开更多

Rewiring and reprogramming of transcriptional regulation took place during bacterial speciation.The mechanistic alterations among tran-scription factors,cis-regulatory elements and target genes confer bacteria novel ability to adapt to stochastic environmental changes.This process is critical to their survival,especially for bacterial pathogens subjected to accelerated evolution.In the past two decades,the investigators not only completed the sequences of numerous bacterial genomes,but also made great progress in understanding the molecular basis of evolution.Here we briefly reviewed the current knowledge on the mechanistic changes among orthologous,paralogous and xenogenic regulatory circuits,which were caused by genetic recombinations such as gene duplication,horizontal gene transfer,transposable elements and different genetic contexts.We also discussed the potential impact of this area on theoretical and applied studies of microbes. 展开更多

Insects represent one of the most evolutionarily successful groups,with their diversity hypothesized to be related to the regulatory roles of Hox genes,a set of related genes encoding homeodomain transcription factors determining the identity of segments along the anterior-posterior axis of the embryo.However,functional insights into the roles of Hox genes in primitive ametabolous insects,which represent the critical transition from aquatic crustaceans to winged insects,have been limited.In this study,we identified complete protein-coding sequences of 10 Hox genes in the Zygentoma Thermobia domestica,and applied clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated nuclease 9(Cas 9)mediated gene knockout(KO)to decipher their functions.We found that the roles of pb,Dfd,and Scr are vital in specifying the appendages of the head in T.domestica,and these roles are relatively conserved in crustaceans and winged insects.Antp is essential for the development of the prothorax segment and the first pair of legs in T.domestica.Ubx and abd-A fully repress appendage development in the abdomen of T.domestica,which implies a functional switch from crustaceans to insects.Additionally,the role of ftz in segmenting the abdomen of T.domestica suggests it has acquired new functions in primitive insects,beyond its traditional Hox-like roles.Although KOs of lab,Hox3,and Abd-B did not result in obvious external phenotypic changes,they led to a significant decrease in hatching rates and substantial deviations in daily survival numbers compared to the negative control.These findings underscore the indispensable roles of all Hox genes during the embryonic development of T.domestica.Our study sheds new light on the functional evolution of Hox genes in ametabolous insects and enhances our understanding of the genetic underpinnings of insect development and diversification. 展开更多
