SELECTION AND GENOMES. “Even though the effects of selection on linked neutral diversity (linked selection) within populations are well documented, recent observations of diversity and differentiation landscapes that are highly correlated even among independent lineages suggest that the effects of long-term linked selection may have a deeper impact on the evolution of the genomic landscapes of diversity and differentiation than previously anticipated.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn

GENOMES AND DIFFERENTIATION. “The genomic landscape of differentiation is usually highly heterogeneous, with regions of accentuated differentiation widespread across the genome. Although this is one of the best consolidated patterns established by a decade's efforts to identify genomic regions involved in adaptation and speciation, the processes involved in its evolution remain more controversial.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn

DIFFERENTIATION. “Originally interpreted as a footprint of selective sweeps or selection against gene flow, accentuated differentiation has now repeatedly been associated with genomic regions of low recombination, suggesting an important role for linked selection in its evolution.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn

NEW THINKING. “Awareness is therefore rising that not only positive selection associated with adaptation or speciation, but also background selection, can have an important role in driving the evolution of the genomic landscapes of diversity and differentiation.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn

DISPLACED CONCEPT. “Linked selection may have further reaching consequences than anticipated so far, putting even the previous golden standard practice of replication and the inference of parallel evolution into the line of fire.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn

DIVERSITY GENOMES. “Correlated genomic landscapes in birds have persisted over tens of millions of years, making a strong case for genomic features—in particular recombination rate—in governing the genomic landscapes of diversity and differentiation.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn

GENOMIC LANDSCAPES. “The observed correlations are a direct prediction of long-term linked selection in heterogeneous recombination landscapes that are conserved among species.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn

LINKED SELECTION. “In genome regions in which low-recombination rate is conserved across multiple consecutive speciation events, the diversity-reducing effects of linked selection accumulate across extended periods of time.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn

INHERITANCE. “As a result, along with heterogeneous recombination landscapes, ancestors transmit a diversity landscape to their daughter species whose heterogeneity may continue to be maintained by liked selection for as long as the recombination landscape persists.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn

DIVERSITY LANDSCAPE. “The extended periods of time across which this process is active have two notable implications: the slow process of background selection alone might suffice for the evolution of correlated differentiation landscapes, and sweeps in the ancestral (as opposed to extant) lineage may make contributions to extant genomic landscapes of diversity and differentiation.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn
