  text: Understanding population divergence that eventually leads to speciation is
    essential for evolutionary biology. High species diversity in the sea was regarded
    as a paradox when strict allopatry was considered necessary for most speciation
    events because geographical barriers seemed largely absent in the sea, and many
    marine species have high dispersal capacities. Combining genome-wide data with
    demographic modelling to infer the demographic history of divergence has introduced
    new ways to address this classical issue. These models assume an ancestral population
    that splits into two subpopulations diverging according to different scenarios
    that allow tests for periods of gene flow. Models can also test for heterogeneities
    in population sizes and migration rates along the genome to account, respectively,
    for background selection and selection against introgressed ancestry. To investigate
    how barriers to gene flow arise in the sea, we compiled studies modelling the
    demographic history of divergence in marine organisms and extracted preferred
    demographic scenarios together with estimates of demographic parameters. These
    studies show that geographical barriers to gene flow do exist in the sea but that
    divergence can also occur without strict isolation. Heterogeneity of gene flow
    was detected in most population pairs suggesting the predominance of semipermeable
    barriers during divergence. We found a weak positive relationship between the
    fraction of the genome experiencing reduced gene flow and levels of genome-wide
    differentiation. Furthermore, we found that the upper bound of the ‘grey zone
    of speciation’ for our dataset extended beyond that found before, implying that
    gene flow between diverging taxa is possible at higher levels of divergence than
    previously thought. Finally, we list recommendations for further strengthening
    the use of demographic modelling in speciation research. These include a more
    balanced representation of taxa, more consistent and comprehensive modelling,
    clear reporting of results and simulation studies to rule out nonbiological explanations
    for general results.

  text: Eurasian brine shrimp (genus Artemia) have closely related sexual and asexual
    lineages of parthenogenetic females, which produce rare males at low frequencies.
    Although they are known to have ZW chromosomes, these are not well characterized,
    and it is unclear whether they are shared across the clade. Furthermore, the underlying
    genetic architecture of the transmission of asexuality, which can occur when rare
    males mate with closely related sexual females, is not well understood. We produced
    a chromosome-level assembly for the sexual Eurasian species Artemia sinica and
    characterized in detail the pair of sex chromosomes of this species. We combined
    this new assembly with short-read genomic data for the sexual species Artemia
    sp. Kazakhstan and several asexual lineages of Artemia parthenogenetica, allowing
    us to perform an in-depth characterization of sex-chromosome evolution across
    the genus. We identified a small differentiated region of the ZW pair that is
    shared by all sexual and asexual lineages, supporting the shared ancestry of the
    sex chromosomes. We also inferred that recombination suppression has spread to
    larger sections of the chromosome independently in the American and Eurasian lineages.
    Finally, we took advantage of a rare male, which we backcrossed to sexual females,
    to explore the genetic basis of asexuality. Our results suggest that parthenogenesis
    is likely partly controlled by a locus on the Z chromosome, highlighting the interplay
    between sex determination and asexuality.

  text: The Mytilus complex of marine mussel species forms a mosaic of hybrid zones,
    found across temperate regions of the globe. This allows us to study ‘replicated’
    instances of secondary contact between closely related species. Previous work
    on this complex has shown that local introgression is both widespread and highly
    heterogeneous, and has identified SNPs that are outliers of differentiation between
    lineages. Here, we developed an ancestry‐informative panel of such SNPs. We then
    compared their frequencies in newly sampled populations, including samples from
    within the hybrid zones, and parental populations at different distances from
    the contact. Results show that close to the hybrid zones, some outlier loci are
    near to fixation for the heterospecific allele, suggesting enhanced local introgression,
    or the local sweep of a shared ancestral allele. Conversely, genomic cline analyses,
    treating local parental populations as the reference, reveal a globally high concordance
    among loci, albeit with a few signals of asymmetric introgression. Enhanced local
    introgression at specific loci is consistent with the early transfer of adaptive
    variants after contact, possibly including asymmetric bi‐stable variants (Dobzhansky‐Muller
    incompatibilities), or haplotypes loaded with fewer deleterious mutations. Having
    escaped one barrier, however, these variants can be trapped or delayed at the
    next barrier, confining the introgression locally. These results shed light on
    the decay of species barriers during phases of contact.

  text: Domestication is a human‐induced selection process that imprints the genomes
    of domesticated populations over a short evolutionary time scale and that occurs
    in a given demographic context. Reconstructing historical gene flow, effective
    population size changes and their timing is therefore of fundamental interest
    to understand how plant demography and human selection jointly shape genomic divergence
    during domestication. Yet, the comparison under a single statistical framework
    of independent domestication histories across different crop species has been
    little evaluated so far. Thus, it is unclear whether domestication leads to convergent
    demographic changes that similarly affect crop genomes. To address this question,
    we used existing and new transcriptome data on three crop species of Solanaceae
    (eggplant, pepper and tomato), together with their close wild relatives. We fitted
    twelve demographic models of increasing complexity on the unfolded joint allele
    frequency spectrum for each wild/crop pair, and we found evidence for both shared
    and species‐specific demographic processes between species. A convergent history
    of domestication with gene flow was inferred for all three species, along with
    evidence of strong reduction in the effective population size during the cultivation
    stage of tomato and pepper. The absence of any reduction in size of the crop in
    eggplant stands out from the classical view of the domestication process; as does
    the existence of a “protracted period” of management before cultivation. Our results
    also suggest divergent management strategies of modern cultivars among species
    as their current demography substantially differs. Finally, the timing of domestication
    is species‐specific and supported by the few historical records available.

  text: 'We present DILS, a deployable statistical analysis platform for conducting
    demographic inferences with linked selection from population genomic data using
    an Approximate Bayesian Computation framework. DILS takes as input single‐population
    or two‐population data sets (multilocus fasta sequences) and performs three types
    of analyses in a hierarchical manner, identifying: (a) the best demographic model
    to study the importance of gene flow and population size change on the genetic
    patterns of polymorphism and divergence, (b) the best genomic model to determine
    whether the effective size Ne and migration rate N, m are heterogeneously distributed
    along the genome (implying linked selection) and (c) loci in genomic regions most
    associated with barriers to gene flow. Also available via a Web interface, an
    objective of DILS is to facilitate collaborative research in speciation genomics.
    Here, we show the performance and limitations of DILS by using simulations and
    finally apply the method to published data on a divergence continuum composed
    by 28 pairs of Mytilus mussel populations/species.'

  text: Interspecific crossing experiments have shown that sex chromosomes play a
    major role in reproductive isolation between many pairs of species. However, their
    ability to act as reproductive barriers, which hamper interspecific genetic exchange,
    has rarely been evaluated quantitatively compared to Autosomes. This genome-wide
    limitation of gene flow is essential for understanding the complete separation
    of species, and thus speciation. Here, we develop a mainland-island model of secondary
    contact between hybridizing species of an XY (or ZW) sexual system. We obtain
    theoretical predictions for the frequency of introgressed alleles, and the strength
    of the barrier to neutral gene flow for the two types of chromosomes carrying
    multiple interspecific barrier loci. Theoretical predictions are obtained for
    scenarios where introgressed alleles are rare. We show that the same analytical
    expressions apply for sex chromosomes and autosomes, but with different sex-averaged
    effective parameters. The specific features of sex chromosomes (hemizygosity and
    absence of recombination in the heterogametic sex) lead to reduced levels of introgression
    on the X (or Z) compared to autosomes. This effect can be enhanced by certain
    types of sex-biased forces, but it remains overall small (except when alleles
    causing incompatibilities are recessive). We discuss these predictions in the
    light of empirical data comprising model-based tests of introgression and cline
    surveys in various biological systems.

  text: Domestication is a human-induced selection process that imprints the genomes
    of domesticated populations over a short evolutionary time scale, and that occurs
    in a given demographic context. Reconstructing historical gene flow, effective
    population size changes and their timing is therefore of fundamental interest
    to understand how plant demography and human selection jointly shape genomic divergence
    during domestication. Yet, the comparison under a single statistical framework
    of independent domestication histories across different crop species has been
    little evaluated so far. Thus, it is unclear whether domestication leads to convergent
    demographic changes that similarly affect crop genomes. To address this question,
    we used existing and new transcriptome data on three crop species of Solanaceae

  text: The Mytilus complex of marine mussel species forms a mosaic of hybrid zones,
    found across temperate regions of the globe. This allows us to study "replicated"
    instances of secondary contact between closely-related species. Previous work
    on this complex has shown that local introgression is both widespread and highly
    heterogeneous, and has identified SNPs that are outliers of differentiation between
    lineages. Here, we developed an ancestry-informative panel of such SNPs. We then
    compared their frequencies in newly-sampled populations, including samples from
    within the hybrid zones, and parental populations at different distances from
    the contact. Results show that close to the hybrid zones, some outlier loci are
    near to fixation for the heterospecific allele, suggesting enhanced local introgression,
    or the local sweep of a shared ancestral allele. Conversely, genomic cline analyses,
    treating local parental populations as the reference, reveal a globally high concordance
    among loci, albeit with a few signals of asymmetric introgression. Enhanced local
    introgression at specific loci is consistent with the early transfer of adaptive
    variants after contact, possibly including asymmetric bi-stable variants (Dobzhansky-Muller
    incompatibilities), or haplotypes loaded with fewer deleterious mutations. Having
    escaped one barrier, however, these variants can be trapped or delayed at the
    next barrier, confining the introgression locally. These results shed light on
    the decay of species barriers during phases of contact.

  text: Fitness interactions between mutations can influence a population’s evolution
    in many different ways. While epistatic effects are difficult to measure precisely,
    important information is captured by the mean and variance of log fitnesses for
    individuals carrying different numbers of mutations. We derive predictions for
    these quantities from a class of simple fitness landscapes, based on models of
    optimizing selection on quantitative traits. We also explore extensions to the
    models, including modular pleiotropy, variable effect sizes, mutational bias and
    maladaptation of the wild type. We illustrate our approach by reanalysing a large
    dataset of mutant effects in a yeast snoRNA. Though characterized by some large
    epistatic effects, these data give a good overall fit to the non-epistatic null
    model, suggesting that epistasis might have limited influence on the evolutionary
    dynamics in this system. We also show how the amount of epistasis depends on both
    the underlying fitness landscape and the distribution of mutations, and so is
    expected to vary in consistent ways between new mutations, standing variation
    and fixed mutations.

  text: 'Plant mating systems play a key role in structuring genetic variation both
    within and between species. In hybrid zones, the outcomes and dynamics of hybridization
    are usually interpreted as the balance between gene flow and selection against
    hybrids. Yet, mating systems can introduce selective forces that alter these expectations;
    with diverse outcomes for the level and direction of gene flow depending on variation
    in outcrossing and whether the mating systems of the species pair are the same
    or divergent. We present a survey of hybridization in 133 species pairs from 41
    plant families and examine how patterns of hybridization vary with mating system.
    We examine if hybrid zone mode, level of gene flow, asymmetries in gene flow and
    the frequency of reproductive isolating barriers vary in relation to mating system/s
    of the species pair. We combine these results with a simulation model and examples
    from the literature to address two general themes: (i) the two‐way interaction
    between introgression and the evolution of reproductive systems, and (ii) how
    mating system can facilitate or restrict interspecific gene flow. We conclude
    that examining mating system with hybridization provides unique opportunities
    to understand divergence and the processes underlying reproductive isolation.'

  text: Pleiotropy is the well-established idea that a single mutation affects multiple
    phenotypes. If a mutation has opposite effects on fitness when expressed in different
    contexts, then genetic conflict arises. Pleiotropic conflict is expected to reduce
    the efficacy of selection by limiting the fixation of beneficial mutations through
    adaptation, and the removal of deleterious mutations through purifying selection.
    Although this has been widely discussed, in particular in the context of a putative
    “gender load,” it has yet to be systematically quantified. In this work, we empirically
    estimate to which extent different pleiotropic regimes impede the efficacy of
    selection in Drosophila melanogaster. We use whole-genome polymorphism data from
    a single African population and divergence data from D. simulans to estimate the
    fraction of adaptive fixations (α), the rate of adaptation (ωA), and the direction
    of selection (DoS). After controlling for confounding covariates, we find that
    the different pleiotropic regimes have a relatively small, but significant, effect
    on selection efficacy. Specifically, our results suggest that pleiotropic sexual
    antagonism may restrict the efficacy of selection, but that this conflict can
    be resolved by limiting the expression of genes to the sex where they are beneficial.
    Intermediate levels of pleiotropy across tissues and life stages can also lead
    to maladaptation in D. melanogaster, due to inefficient purifying selection combined
    with low frequency of mutations that confer a selective advantage. Thus, our study
    highlights the need to consider the efficacy of selection in the context of antagonistic
    pleiotropy, and of genetic conflict in general.

  text: "One of the most striking and consistent results in speciation genomics is
    the heterogeneous divergence observed across the genomes of closely related species.
    This pattern was initially attributed to different levels of gene exchange—with
    divergence preserved at loci generating a barrier to gene flow but homogenized
    at unlinked neutral loci. Although there is evidence to support this model, it
    is now recognized that interpreting patterns of divergence across genomes is not
    so straightforward. One \r\nproblem is that heterogenous divergence between populations
    can also be generated by other processes (e.g. recurrent selective sweeps or background
    selection) without any involvement of differential gene flow. Thus, integrated
    studies that identify which loci are likely subject to divergent selection are
    required to shed light on the interplay between selection and gene flow during
    the early phases of speciation. In this issue of Molecular Ecology, Rifkin et
    al. (2019) confront this challenge using a pair of sister morning glory species.
    They wisely design their sampling to take the geographic context of individuals
    into account, including geographically isolated (allopatric) and co‐occurring
    (sympatric) populations. This enabled them to show that individuals are phenotypically
    less differentiated in sympatry. They also found that the loci that resist introgression
    are enriched for those most differentiated in allopatry and loci that exhibit
    signals of divergent selection. One great strength of the \r\nstudy is the combination
    of methods from population genetics and molecular evolution, including the development
    of a model to simultaneously infer admixture proportions and selfing rates."

  text: Fitness interactions between mutations can influence a population’s evolution
    in many different ways. While epistatic effects are difficult to measure precisely,
    important information is captured by the mean and variance of log fitnesses for
    individuals carrying different numbers of mutations. We derive predictions for
    these quantities from a class of simple fitness landscapes, based on models of
    optimizing selection on quantitative traits. We also explore extensions to the
    models, including modular pleiotropy, variable effect sizes, mutational bias and
    maladaptation of the wild type. We illustrate our approach by reanalysing a large
    dataset of mutant effects in a yeast snoRNA (small nucleolar RNA). Though characterized
    by some large epistatic effects, these data give a good overall fit to the non-epistatic
    null model, suggesting that epistasis might have limited influence on the evolutionary
    dynamics in this system. We also show how the amount of epistasis depends on both
    the underlying fitness landscape and the distribution of mutations, and so is
    expected to vary in consistent ways between new mutations, standing variation
    and fixed mutations.

    divergence. However, extracting the full demographic information from these data
    is not trivial, and requires inferential methods that account for the diversity
    of coalescent histories throughout the genome. Here, we evaluate the potential
    and limitations of one such approach. We reexamine a well-known system of mussel
    sister species, using the joint site frequency spectrum (jSFS) of synonymousmutations
    computed either fromexome capture or RNA-seq, in an Approximate Bayesian Computation
    (ABC) framework. We first assess the best sampling strategy (number of: individuals,
    loci, and bins in the jSFS), and show that model selection is robust to variation
    in the number of individuals and loci. In contrast, different binning choices
    when summarizing the jSFS, strongly affect the results: including classes of low
    and high frequency shared polymorphisms can more effectively reveal recent migration
    events. We then take advantage of the flexibility of ABC to compare more realistic
    models of speciation, including variation in migration rates through time (i.e.,
    periodic connectivity) and across genes (i.e., genome-wide heterogeneity in migration
    rates). We show that these models were consistently selected as the most probable,
    suggesting that mussels have experienced a complex history of gene flow during
    divergence and that the species boundary is semi-permeable. Our work provides
    a comprehensive evaluation of ABC demographic inference in mussels based on the
    coding jSFS, and supplies guidelines for employing different sequencing techniques
    and sampling strategies. We emphasize, perhaps surprisingly, that inferences are
    less limited by the volume of data, than by the way in which they are analyzed.'

  text: 'Moths and butterflies (Lepidoptera) usually have a pair of differentiated
    WZ sex chromosomes. However, in most lineages outside of the division Ditrysia,
    as well as in the sister order Trichoptera, females lack a W chromosome. The W
    is therefore thought to have been acquired secondarily. Here we compare the genomes
    of three Lepidoptera species (one Dytrisia and two non-Dytrisia) to test three
    models accounting for the origin of the W: (1) a Z-autosome fusion; (2) a sex
    chromosome turnover; and (3) a non-canonical mechanism (e.g., through the recruitment
    of a B chromosome). We show that the gene content of the Z is highly conserved
    across Lepidoptera (rejecting a sex chromosome turnover) and that very few genes
    moved onto the Z in the common ancestor of the Ditrysia (arguing against a Z-autosome
    fusion). Our comparative genomics analysis therefore supports the secondary acquisition
    of the Lepidoptera W by a non-canonical mechanism, and it confirms the extreme
    stability of well-differentiated sex chromosomes.'

  text: Speciation results from the progressive accumulation of mutations that decrease
    the probability of mating between parental populations or reduce the fitness of
    hybrids—the so-called species barriers. The speciation genomic literature, however,
    is mainly a collection of case studies, each with its own approach and specificities,
    such that a global view of the gradual process of evolution from one to two species
    is currently lacking. Of primary importance is the prevalence of gene flow between
    diverging entities, which is central in most species concepts and has been widely
    discussed in recent years. Here, we explore the continuum of speciation thanks
    to a comparative analysis of genomic data from 61 pairs of populations/species
    of animals with variable levels of divergence. Gene flow between diverging gene
    pools is assessed under an approximate Bayesian computation (ABC) framework. We
    show that the intermediate &quot;grey zone&quot; of speciation, in which taxonomy
    is often controversial, spans from 0.5% to 2% of net synonymous divergence, irrespective
    of species life history traits or ecology. Thanks to appropriate modeling of among-locus
    variation in genetic drift and introgression rate, we clarify the status of the
    majority of ambiguous cases and uncover a number of cryptic species. Our analysis
    also reveals the high incidence in animals of semi-isolated species (when some
    but not all loci are affected by barriers to gene flow) and highlights the intrinsic
    difficulty, both statistical and conceptual, of delineating species in the grey
    zone of speciation.
