Summary Biodiversity hotspots, such as the Caucasus mountains, provide unprecedented opportunities for understanding evolutionary processes that shape species diversity and richness. Therefore, we investigated evolution of Primula sect. , a clade with high degree endemism in Caucasus. We performed phylogenetic network analyses whole‐genome resequencing data from entire nuclear genome, chloroplast heterostyly supergene. The different characteristics genomic partitions resulting incongruences enabled us to disentangle histories tokogenetic vs cladogenetic processes. first phylogeny inferred supergene includes all . Our results identified recurrent admixture at deep nodes between lineages cause non‐monophyly Biogeographic support ‘out‐of‐the‐Caucasus’ hypothesis, emphasizing importance this hotspot cradle biodiversity. findings novel insights into causal discordance, demonstrating genome‐wide contrasting genetic broad geographic sampling are crucial disentangling diversification species‐rich clades biodiversity hotspots.

In this study we detangled the evolutionary history of Patagonian lizard clade Liolaemus kingii, coupling dense geographic sampling and novel computational analytical approaches. We analyzed nuclear mitochondrial data (restriction site-associated DNA sequencing cytochrome b) to hypothesize evaluate species limits, phylogenetic relationships, demographic histories. complemented these analyses with posterior predictive simulations assess fit genomic multispecies coalescent model. also employed a approach time-calibrate network. Our results show several instances mito-nuclear discordance consistent support for reticulated history, supporting view that complex kingii is characterized by extensive gene flow rapid diversification events. discuss our findings in contexts "gray zone" speciation, phylogeographic patterns region, taxonomic outcomes.

Adaptive radiations are rich laboratories for exploring, testing, and understanding key theories in evolution ecology because they offer spectacular displays of speciation ecological adaptation. Particular challenges to the study adaptive radiation include high levels species richness, rapid speciation, gene flow between species. Over last decade, high-throughput sequencing technologies access population genomic data have lessened these by enabling analysis samples from many individual organisms at whole-genome scales. Here we review how facilitated our knowledge five areas: (1) phylogenetics, (2) hybridization, (3) timing rates diversification, (4) basis trait evolution, (5) role genome structure divergence. We current each area, highlight outstanding questions, focus on methods that facilitate detection complex patterns divergence demography populations through time. It is clear revolutionising ability reconstruct evolutionary history rapidly diversifying clades. Additionally, studies increasingly emphasising central flow, re-use standing genetic variation during adaptation, structural elements as facilitators process radiations. hybridization-and hypothesized processes which it shapes diversification-and questions seeking bridge divide microevolutionary macroevolutionary areas future study. Overall, has an exciting era research, with implications deeper fundamental across tree life.

Abstract Evolutionary correlations between phenotypic and environmental traits characterize adaptive radiations. However, the lizard genus Liolaemus , one of most ecologically diverse terrestrial vertebrate radiations on earth, has so far shown limited or mixed evidence diversification in phenotype. Restricted use comprehensive data, incomplete taxonomic representation not considering phylogenetic uncertainty may have led to contradictory evidence. We compiled a 26‐taxon dataset for gracilis species group, representing much ecological diversity represented within used data how environments occupied by species' relate evolution. Our analyses, explicitly accounting uncertainty, suggest toward present, with body shape evolution rapidly evolving this group.

ABSTRACT Gene-flow processes such as hybridization and introgression play important roles in shaping diversity across the tree of life. Recent studies extending birth-death models have made it possible to investigate patterns reticulation a macroevolutionary context. These allow for different gene flow events that can either add, maintain, or remove lineages—with itself possibly being dependent on relatedness between species—thus creating complex diversification scenarios. Further, many reticulate phylogenetic inference methods assume specific structures phylogenies belonging certain network classes. However, distributions networks under are poorly characterized, is unknown whether they violate common methodological assumptions. We use simulation techniques explore space birth-death-hybridization process where rate linear dependence genetic distance. Specifically, we measured number lineages through time role along with proportion belong commonly used classes (e.g., tree-child, tree-based, level-1 networks). find growth class membership largely affected by assumptions about flow. In accordance previous studies, lower belonged these based type density events. process, factors form an antagonistic relationship; cause high proportions also lead highest density, consequently lowering overall some observed distance–dependent incomplete sampling increase membership, primarily due having fewer Our results inform if their biological expectations associated evolutionary histories satisfy current methodology aid finding relevant development.
