Phylogenetic and computational methods reveal that at least two seasonal coronaviruses are evolving adaptively in the region of the viral spike protein exposed to the human humoral immune system.

Life-threatening S. aureus infections emerge from commensal nose bacteria in association with repeatable adaptive evolution.

High-resolution foveal imaging and micro-psychophysics reveal that the human oculomotor system finely adjusts drift motion of the eye in an acuity task to enhance retinal sampling, achieving sub-cell resolution.

An identical DNA base pair change has occurred in divergent sticklebacks to alter the expression of a major developmental gene controlling armor plates, thus providing a molecular link between particular enhancer changes, cell signaling, and repeated skeletal evolution in natural populations.

Integration of evolutionary dynamics framed through a mathematical model improved outcomes in abiraterone monotherapy for the treatment of metastatic castrate-resistant prostate cancer.

A series of selective events, each improving fitness relative to an immediate predecessor, can result in organisms that are less fit compared to a distant ancestor.

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.

Disentangling the different selective forces shaping the evolutionary dynamics of transposable elements (TEs) in the wild grass Brachypodium distachyon.

A new model describes how adaptive molecular evolution shapes phylogenetic trees and can be used to estimate the fitness effects of mutations from phylogenies.

Ageing is broadly accepted as a by-product of evolution, as thus, models allowing to conceive ageing as an adaptive force of evolution could show significant importance at a time of biogerontology mostly aiming at curing ageing.
