On the origin of an insular hybrid butterfly lineage
Evolution; International Journal of Organic EvolutionAbstract A new species can form through hybridization between species. Hybrid speciation in animals has been intensely debated, partly because hard evidence for the process has been difficult to obtain. Here, we report the discovery of a European hybrid butterfly lineage, a finding that can be considered surprising given the intense ...

Single-cell lineage tracing of metastatic cancer reveals selection of hybrid EMT states
Cancer Cell, 2021 The underpinnings of cancer metastasis remain poorly understood, in part due to a lack of tools for probing their emergence at high resolution. Here we present macsGESTALT, an inducible CRISPR-Cas9-based lineage recorder with highly efficient single-cell

Ancient hybridization underlies tuberization and radiation of the potato lineage
CellInterspecific hybridization may trigger species radiation by creating allele combinations and traits. Cultivated potato and its 107 wild relatives from the Petota lineage all share the distinctive trait of underground tubers, but the underlying mechanisms for tuberization and its relationship to extensive species diversification remain unclear. Through

An island ‘endemic’ born out of hybridization between introduced lineages
Molecular Ecology, 2022Abstract Humans have profoundly impacted the distribution of plant and animal species over thousands of years. The most direct example of these effects is human‐mediated movement of individuals, either through translocation of individuals within their range or through the introduction of species to new habitats ...

A Statistical Approach for Distinguishing Hybridization and Incomplete Lineage Sorting
The American Naturalist, 2009The extent and evolutionary significance of hybridization is difficult to evaluate because of the difficulty in distinguishing hybridization from incomplete lineage sorting. Here we present a novel parametric approach for statistically distinguishing hybridization from incomplete lineage sorting based on minimum genetic distances of a nonrecombining ...

Maternal lineages ofPinus densata, a diploid hybrid
Molecular Ecology, 2002AbstractPrevious morphological, allozyme and chloroplast DNA data have suggested thatPinus densataoriginated through hybridization betweenP.tabuliformis andP.yunnanensis. In the present study, sequence and restriction site analyses of maternally inherited mitochondrialnad1 intron were used to detect variation patterns in 19 populations ofP.tabuliformis,

Transgenerational selection driven by divergent ecological impacts of hybridizing lineages
Nature Ecology & Evolution, 2017Dynamic interactions between ecological conditions and the phenotypic composition of populations likely play an important role in evolution, but the direction and strength of these feedbacks remain difficult to characterize. We investigated these dynamics across two generations of threespine sticklebacks from two evolutionary lineages undergoing ...

Lineage-specific gene acquisition or loss is involved in interspecific hybrid sterility in rice
Proceedings of the National Academy of Sciences of the United States of America, 2018 Understanding the genetic basis of reproductive barriers between species has been a central issue in evolutionary biology. The S 1 locus in rice causes hybrid sterility and is a

Experimental evidence for hybridization of closely related lineages in Plasmodium relictum
Molecular and Biochemical Parasitology, 2017Over 50 avian Plasmodium species have been described. However, PCR-based information shows much broader diversity of genetic lineages in these parasites. This discrepancy indicates insufficient knowledge about taxonomic diversity and boundaries of a single species in avian Plasmodium species.

The Cayratia japonica-Cayratia tenuifolia species complex (Vitaceae) is distributed from temperate to tropical East Asia, Southeast Asia, India, and Australia. The spatiotemporal diversification history of this complex was assessed through phylogenetic and biogeographic analyses.
