Summary: Introgressive hybridization is an important process in evolution. The analysis of whole-genome sequences of nine-spined sticklebacks in northern Europe revealed a complex pattern of population ancestry. Freshwater isolates provided insights into the past and intermediate states of evolutionary processes.

Summary: S* is a widely used statistic for detecting archaic admixture from population genetic data. We implemented sstar, which is robust to differences in demographic models and can be used for detecting introgressed fragments in various scenarios and in non-human species.

Summary: Invasive species can affect native populations through a variety of mechanisms, including competition, predation, habitat alteration, disease transmission, and hybridization. In this study, researchers investigated the hybridization between a native green anole lizard and an invasive species in south Florida. The findings showed evidence of introgression and a diverse range of ancestry proportions in the hybrid population. They also found a positive correlation between urbanization and non-native ancestry. Overall, the study highlights the persistence of non-native genetic material and the potential for adaptive introgression in the face of anthropogenic global change.

Summary: Geneticists have made significant progress in understanding human genetic diversity, particularly in the field of admixture population genetics. Admixture is an important evolutionary process that affects genetic variation and evolution between populations. Overcoming limitations in studying admixed populations using traditional methods, researchers have leveraged genomic signatures to gain insights into human history, natural selection, and complex trait architecture.

Summary: The research focuses on the interbreeding between different human lineages over the past hundred thousand years, specifically the Neandertals and modern humans. The study suggests that the introduction of Neandertal genes into the genomes of modern humans primarily occurred in the Near East region.

Summary: This study focused on a Native American population with high Native American genetic ancestry, aiming to investigate the impact of this ancestry on skin color variation. The results showed that Native American genetic ancestry had the greatest effect on reducing skin pigmentation, while genetic mutations from European and African ancestries had smaller effects. However, the specific genetic variants responsible for light skin in Native American/East Asian populations remain to be identified.

Summary: This study examines the genetic population structure and dispersal patterns of the Western Grasswren in Western Australia. It finds that geographical landforms, such as peninsulas, can act as barriers to gene flow and lead to genetic divergence between subpopulations. The research highlights the importance of conservation efforts to protect these genetically distinct populations in the future.

Summary: Present-day African cattle have a unique genetic profile resulting from a mixture of Bos taurus and Bos indicus populations. Research suggests that the earliest domestic cattle in Africa likely had a significant contribution from an extinct African aurochs lineage, and the indicine ancestry of African cattle is closely related to both North Indian and Southeast Asian indicine breeds.

Summary: The indigenous population of the UAE has a unique demographic and cultural history, characterized by endogamy and consanguinity. This has led to genetic homogeneity and partitioning of gene pools. However, population movements and intercontinental trade have contributed to genetic diversity. This study explores the genetic structure of the Emirati population using genotype data from 1,198 individuals and reveals shared ancestry, gene flow with neighboring populations, and the influence of endogamous and consanguineous cultural traditions.

Summary: The study on the genetic structure of Turkey reveals a closer genetic relationship of the Turkish population to Europeans. A Turkish Variome has been established as a valuable resource for identifying disease genes in Turkey and for facilitating genome-wide association studies.

Summary: This study assessed the level of genetic introgression between red foxes bred on fur farms in Poland and the native wild population, finding significant genetic differentiation and no strong admixture signals between the two groups. The genetic structure analysis showed distinct clusters for farm and wild foxes, with no threat to the genetic integrity of the species.

Summary: It is found that the mutation load in an admixed population resulting from introgression between individuals with different N-e is intermediate between those of the parental populations and positively correlated with the proportion of ancestry of the subspecies. Therefore, considering the genetic admixture of populations is crucial in estimating mutation loads.

Summary: The study analyzed high-coverage genomes of 317 individuals from 20 populations in the Pacific region, revealing a strong bottleneck in the ancestors of Oceanian populations before their settlement and a divergence between East Asian Pacific populations and Taiwanese Indigenous peoples before the Neolithic expansion. The research also showed significant differences in the Denisovan genetic contribution among Pacific groups and highlighted selective sweeps and polygenic adaptation linked to pathogen exposure and lipid metabolism in the region.

Summary: The study examined genetic diversity of wild Brook Trout populations in Tennessee, finding significant variations in diversity levels and hatchery introgression. Weak relationships between genetic metrics and landscape characteristics suggest the influence of complex history and challenges in defining drainages on genetic structure. The importance of genetic data in guiding management decisions was highlighted, due to the complexities shaping genetic structure and inferring the status of unsampled populations.

Summary: Preferences for mating cues, including odor signals, can impact speciation and reproductive isolation in natural hybrid zones. Hybrid individuals show varying preferences for parental species cues, with male hybrids showing overall no preference and female hybrids showing a preference for black-capped chickadee odor dependent on their black-capped ancestry. These preferences may play a role in reproductive isolation and the movement of hybrid zones.
