Examplesofcetaceancetacean Not only primates and cetaceans, but also other long-lived mammals, like elephants, have females playing active (crucial) post-reproductive roles. From theCambridge English Corpus There is one behavioural pattern seen in group-living cetaceans that is individually maladaptive but could have arisen within a system of conformist traditions: mass stranding. From theCambridge English Corpus Studies of cetaceans have uncovered a number of patterns of behaviour and vocalizations, which some cetologists have ascribed to cultural processes. From theCambridge English Corpus Although the available evidence is consistent with the notion of culture in cetaceans, caution is warranted due to the many gaps in the data. From theCambridge English Corpus The latter seems to be a feature of dolphins and other cetaceans (exploited in oceanaria shows, where two performers leap and dive together). From theCambridge English Corpus Observations can provide additional insights into the products of culture that are important to cetaceans, as well as into the processes that might be involved. From theCambridge English Corpus Consequently, the implication in the target article that, because cetaceans have vocal traditions, they can learn other motor acts by imitation, is not convincing. From theCambridge English Corpus Culture may be an ancestral characteristic of terrestrialcetaceanancestors; not derived via marine variability, modern cetacean mobility, or any living cetacean social structure. From theCambridge English Corpus First, culture may be an ancestral state predating thecetaceansplit from their terrestrial ancestors. From theCambridge English Corpus Finally, the authors' account of the evolution ofcetaceanculture stresses that there are likely to be interesting interactions between migration and culture. From theCambridge English Corpus Such versatility raises the question of how widely social learning is used in less studied species of cetaceans. From theCambridge English Corpus This conclusion is relevant for the broader consideration of what amounts to culture in cetaceans. From theCambridge English Corpus Another difference occurs in the plates relating to the cetaceans. From theCambridge English Corpus Oddly, evidence is viewed differently when produced by cetaceans and birds. From theCambridge English Corpus An experiment could be as simple as introducing interesting artifacts into cetaceans' habitats and observing if (and how) different species interact with them.
