The genetic 'fossil record' of a retroviral lineage over >25 million years of evolution reveals the profound consequences of an ancient recombination event on viral replication mechanisms and genome structure, and identifies an ancient interspecies viral transmission.

The timescale dependence of d_N/d_S in bacteria is better explained by adaptive than purifying dynamics, suggesting comparative genomics can underestimate past adaptation.

Proteins evolve more intrinsic structural disorder under more effective selection, with selection assessed via a novel metric of codon adaptation.

By modulating the intensity of balancing selection at the S-locus, dominance between self-incompatibility alleles shapes the genetic load linked to each allele, creating inbreeding depression in some S-locus homozygotes.

The common ancestor of extant mammalian coronaviruses originated recently in a bat species and their diversification occurred via preferential host switches rather than through codiversification with mammals.

A broad and inclusive view of sex biases in hybrid dysfunction, irrespective of sexual system, expands the reach of Haldane's rule to help characterize the underlying forces and mechanisms responsible for predictable sex biases in evolutionary divergence and speciation.

Porcelaneous foraminifera, marine calcifiers, reveal their biomineralization secrets.

Discovery of new taxon of Saccorhytida suggests that the ground pattern of Ecdysozoa may not be elongated vermiform instead sac-like in shape.

Secondary active transporters can evolve to accommodate a broader range of substrates without losing their original substrate specificities.
