New online! Evolutionary causes and consequences of gene duplication

Evolutionary causes and consequences of gene duplication

Nature Reviews Genetics, Published online: 16 February 2026; doi:10.1038/s41576-026-00935-5Gene duplication is a key evolutionary mechanism, as initially redundant paralogues diverge over time. The authors review how adaptive and non-adaptive forces influence the evolutionary fates of gene duplicates, highlighting the importance of function–fitness relationships and gene expression dynamics.

New paper out: “allopatric” Drosophila species aren’t so allopatric after all. We show that most currently allopatric species pairs probably overlapped in the past and exchanged genes at levels similar to sympatric pairs. @evolletters.bsky.social doi.org/10.1093/evle... [1/6]

Genomic analyses in Drosophila do not support the classic allopatric model of speciation

Abstract. The allopatric model of speciation has dominated our understanding of speciation biology and biogeography since the Modern Synthesis. It is uncon

This is a disaster. I would not be where I am today without the constructive (and yes, sometimes frustrating) reviews my NSF proposals received as a young investigator. This feedback didn't come from the POs but rather the peer reviewers and panelists who saw how I was trying to enter the field

HL Eisthen, defective human product@hleisthen.bsky.social · 8mo ago

NSF now planning to let POs largely decide what gets funded, and to send PIs reviews that are only 3-5 sentences long. They don't have to use outside reviewers (except maybe 1) and don't have to convene panels. (1/5)
