Gene transfers have been critical to the origin and evolution of endosymbiotic organelles. But just how much, and what are the challenges with detecting them. @fburki co-authored this book chapter that delves into these questions. link.springer.com/chapter/10…

The Extent, Role, and Timing of Endosymbiotic Gene Transfer in Plastid

Endosymbiotic gene transfer (EGT), the transfer of endosymbiont genes to the host nucleus, is considered a fundamental process of plastid endosymbiosis. Together with retargeting of the protein...

Experimental models to study the evolution of primary sex-determining loci are scarce. This study led by Xuan Li shows that male-determining loci on polymorphic proto-Y chromosomes of the housefly can genomically diverge into regions of various complexity. nature.com/articles/s41467-0…

We've just published a comparative genomic analysis of Ascetosporean parasites (Rhizaria). We produced genomic data for two additional classes (Haplosporidia and Paramyxida), and the undescribed Cercozoa M6MM, and combined that to the available mikrocitids bmcbiol.biomedcentral.com/ar…

Here we estimate the number of recent bird extinctions, including those that have gone unnoticed due to a lack of data/research effort. See the popular science summary of our study in The Guardian here: amp.theguardian.com/environm…

Human-driven extinction of bird species twice as high as thought, study says

About 12% of birds have died out as result of human activity in past 120,000 years, say scientists
