驯化会极大地改变行为，包括交流，就像狗（Canis familiaris）和狼（Canis lupus）一样。我们测试的假设，驯化可能会影响一个古老的，共享的沟通形式的犬科动物，嚎叫，似乎有较高的个体差异的狗：嚎叫的感知和使用可能会受到影响的品种的遗传相关性，他们的最后共同祖先与狼（“根距离”）和其他个人特征，如年龄，性别和生殖状态。我们将68只纯种狗暴露在狼的嚎叫声中，并记录它们的反应。我们确定了根距离和年龄对狗的声音和行为反应之间的相互作用：来自更古老品种的老狗对嚎叫的反应更长，表现出更多的压力行为。我们的研究结果表明，驯化影响声乐行为显着：瓦解嚎叫，中央，种属特定的通信形式的犬科动物，并逐步消除它从狗的剧目。家犬品种失去了与嚎叫有关的类似嚎叫的声音和行为反应，因为它们在基因上与狼的距离越来越远。
Domestication dramatically changes behaviour, including communication, as seen in the case of dogs (Canis familiaris) and wolves (Canis lupus). We tested the hypothesis that domestication may affect an ancient, shared communication form of canids, the howling which seems to have higher individual variation in dogs: the perception and usage of howls may be affected by the genetic relatedness of the breeds to their last common ancestor with wolves (‘root distance’) and by other individual features like age, sex, and reproductive status. We exposed 68 purebred dogs to wolf howl playbacks and recorded their responses. We identified an interaction between root distance and age on the dogs’ vocal and behavioural responses: older dogs from more ancient breeds responded longer with howls and showed more stress behaviours. Our results suggest that domestication impacts vocal behaviour significantly: disintegrating howling, a central, species-specific communication form of canids and gradually eradicating it from dogs’ repertoire. Domestic dog breeds lose the wolf-like vocal and behavioural responses connected to howling as they become more genetically distant from wolves.
