Diverse pathways to speciation revealed by marine snails

Trends in Genetics, Journal Year: 2024, Volume and Issue: 40(4), P. 337 - 351

Published: Feb. 22, 2024

Speciation is a key evolutionary process that not yet fully understood. Combining population genomic and ecological data from multiple diverging pairs of marine snails (Littorina) supports the search for speciation mechanisms. Placing on one-dimensional continuum, undifferentiated populations to species, obscured complexity speciation. Adding axes helped describe either routes or reproductive isolation in snails. Divergent selection repeatedly generated barriers between ecotypes, but appeared less important completing while genetic incompatibilities played role. Chromosomal inversions contributed barriers, with variable impact. A multidimensional (hypercube) approach supported framing questions identification knowledge gaps can be useful understand many other systems.

Epigenetic variation in light of population genetic practice

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: Jan. 25, 2025

The evolutionary impact of epigenetic variation depends on its transgenerational stability and source - whether genetically determined, environmentally induced, or due to spontaneous, genotype-independent mutations. Here, we evaluate current approaches for investigating an independent role epigenetics in evolution, pinpointing methodological challenges. We further identify opportunities arising from integrating data with population genetic analyses natural populations. Efforts advance quality, study design, statistical treatment are encouraged consolidate our understanding the heritable variation, quantify autonomous potential enrich additional layer information.

Pervasive gene flow despite strong and varied reproductive barriers in swordtails

Abstract The evolution of reproductive barriers leads to the formation new species. However, recent research has demonstrated that hybridization been pervasive across tree life even in presence strong barriers. Using swordtail fishes (genus Xiphophorus ), an emerging model system, we document overlapping mechanisms act as gene flow between birchmanni and cortezi by combining genomic sequencing from natural hybrid populations, experimental laboratory crosses, behavioural assays, sperm measures developmental studies. We show assortative mating plays a role maintaining subpopulations with distinct ancestry within populations. F 2 hybrids identify several regions strongly impact viability.

Moreover, mismatch at incompatible remarkably similar consequences for phenotypes survival × hybrids. findings varied shape exchange naturally hybridizing highlight complex evolutionary outcomes hybridization.

Local adaptation and reproductive isolation: when does speciation start?

Evolutionary Journal of the Linnean Society, Journal Year: 2024, Volume and Issue: 3(1)

Published: Jan. 1, 2024

Abstract The speciation process often takes a long time. continuum framework has been useful to reconstruct the evolutionary processes that result in formation of new species but defining when this starts is far from trivial. Although panmictic population considered initial condition speciation, unrealistic for almost all species. Local or divergent adaptation are viewed by many researchers as shape intraspecific diversity and thus not part speciation. We propose reproductive isolation becomes greater than zero, arguing favour alternative view local necessarily involves some isolation, independently whether it results completion Given widespread, consequence most constantly speciating. best represented separate subnetworks, defined within extended fluid spatial networks populations.

Interactions between mechanisms of reproductive isolation

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 21, 2025

Abstract Speciation is responsible for the diversity of species observed today and corresponds to build-up reproductive isolation between populations. Reproductive can be generated by different mechanisms that have been extensively characterized, yet how their interactions affect speciation remains largely unknown. Here, we explicitly model interaction three key (local adaptation, mate choice genetic hybrid incompatibilities) quantifying relative contribution evolution isolation. We modeled two populations exchanging migrants using Fisher Geometric Model local phenotype matching choice, multiple pairs Bateson-Dobzhansky-Muller Incompatibilities (DMI). All were determined same set loci, creating conditions barriers both at population levels. found no cases where evolved. Instead, could evolve depending on migration rate: either adaptation incompatibilities limited migration, or higher migration. Our results showed due ecological differentiation was first far most effective barrier. Finally, demonstrated in a polygenic model, become locally adapted strict they would not accumulate provided there sufficient gene flow.

Genomic incompatibilities are persistent barriers when speciation happens with gene flow in Formica ants
