Differences in the usage of DNA repair pathways may give rise to the unique patterns of Y-linked mutations that, together with natural selection, shape rapid Y chromosome evolution.

Proteolytic activation of a sodium-permeable channel that aids in gas exchange and fluid homeostasis likely evolved at the water to land transition in vertebrates.

An inferred mechanistic model that connects sequence (genotype) to function (constitutive gene expression phenotype) for any random sequence in Escherichia coli reveals the structure of constitutive promoters and how they evolve.

The evolution of division of labour with non-accelerating returns from specialisation can occur for several reasons, including but not limited to topologically constrained group structures, but there must always be a group efficiency benefit and a coordination mechanism is required.

Mating phenotypes are diverse in Schizosaccharomyces pombe and the natural variation can impact the spread of wtf meiotic drivers.

Amino acid and sugar supplement induce appendage/limb regeneration in cnidarians, insects, and mammals.

In the common sunflower, patterns of UV-absorbing pigments are controlled by a newly identified regulatory region and may be under the influence of environmental factors.

An in silico analysis of gap junction proteins supports the hypothesis that connexins replaced the primordial innexins in chordate gap junctions due to an evolutionary bottleneck.

Astyanax mexicanus cavefish cope with hypoxic environments by expanding embryonic hematopoietic domains, increasing the capacity for erythrocyte development, and constitutive overexpression of hypoxia-inducible genes.

A theoretical model that considers the diversity of collateral effects among drug resistance mutations provides insights into the development of robust sequential antibiotic treatments.
