FRAGMENT FROM NATURE focuses on a wide-ranging and interesting article by professor Reto Burri, a German ecologist, about evolution that covers the links between natural selection, demography and genomics, with an emphasis on birds; this covers a sizable chunk of the heart of evolution. https://lnkd.in/d6894Jh View in LinkedIn

TEN YEARS. "A detailed, functional artificial human brain can be built within the next 10 years." (Professor Henry Markram). https://lnkd.in/dQEQUkh 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

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

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

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

ACTIVE SPANDRELS. “In such genomic regions, linkage extends over physically larger genome stretches, and selection affects a particularly high number of linked neutral sites.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn

EVOLUTIONARY SPANDREL. “In genomic regions where recombination is infrequent, accentuated differentiation can evolve as a by-product of diversity reductions unrelated to adaptation or speciation.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn

PURIFYING SELECTION. “Instead of being an effect of selective sweeps or barriers to gene flow, accentuated differentiation can evolve by any process reducing genetic diversity locally within the genome, including purifying selection at linked sites (background selection).” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn

ANOTHER ROUTE. “The genomic landscapes of diversity and differentiation are usually highly heterogeneous, it has also led to the increasing realization that this heterogeneity may evolve under processes other than adaptation or speciation.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn
