Evolutionary novelties underlie sound production in baleen whales
Baleen whales (mysticetes) use vocalizations to mediate their complex social and reproductive behaviours in vast, opaque marine environments1. Adapting to an obligate aquatic lifestyle demanded fundamental physiological changes to efficiently produce sound, including laryngeal specializations2,3,4. Whereas toothed whales (odontocetes) evolved a nasal vocal organ5, mysticetes have been thought to use...Elemans, Coen P H ; Jiang, Weili ; Jensen, Mikkel H ; Pichler, Helena ; Mussman, Bo R …

The expensive-tissue hypothesis may help explain brain-size reduction during domestication
Morphological traits, such as white patches, floppy ears and curly tails, are ubiquitous in domestic animals and are referred to as the ‘domestication syndrome’. A commonly discussed hypothesis that has the potential to provide a unifying explanation for these traits is the ‘neural crest/domestication syndrome hypothesis’. Although this hypothesis has...Lesch, Raffaela ; Kotrschal, Kurt ; Kitchener, Andrew C ; Fitch, W Tecumseh ; Kotrschal, Alexander

Cranial volume and palate length of cats, Felis spp., under domestication, hybridization and in wild populations
Reduced brain size, compared with wild individuals, is argued to be a key characteristic of domesticated mammal species, and often cited as a key component of a putative ‘domestication syndrome’. However, brain size comparisons are often based on old, inaccessible literature and in some cases drew comparisons between domestic animals...Lesch, Raffaela ; Kitchener, Andrew C ; Hantke, Georg ; Kotrschal, Kurt ; Fitch, W Tecumseh
