Pollution in urban areas causes higher rates of mutation than in unpolluted areas. This Perspective discusses the effects of these mutations on the health, evolutionary fitness and ecology of urban organisms.
In this Perspective, the authors discuss current knowledge of deep-time protein preservation and how the chemical changes undergone by proteins affect taphonomic and palaeoproteomic analyses.
Cryptic lineages of morphologically similar but genetically distinct coral taxa occur in many reef systems. This Perspective discusses the relevance of this genetic diversity to studies of coral responses to climate change and to reef conservation and restoration.
This Perspective proposes that the driving force of photoreceptor diversity was visual–motor perception with colour discrimination evolving as a secondary function.
