Male and female Drosophila share core metabolic responses to different nutritional environments, but show opposing patterns of nutrient-dependent reproductive regulation.
Environmental transmission is atypical of symbionts that have undergone genome degradation, yet genetically reduced deep-sea anglerfish symbionts likely persist in the deep sea biome in search of a new host.
A female specifically expressed new protein-coding gene that has emerged out of non-coding sequences without detectable signatures of adaptive evolution affects female pregnancy cycles.

Despite risks of infection and reduced fitness, tooth fracture frequency in gray wolves increases rapidly when prey are scarce because they must consume carcasses more completely.

While movement of Fgf-signaling to the limb mesenchyme accompanied a shift in function, the ultimate outcome remains a convergent tetrapod limb phenotype.
