The relative importance of adaptation and individual ontogenetic experience in dogs' high levels of behavioral compatibility with humans has been a topic of intense scientific attention over the past two decades. Salomons et al. Current Biology, 31, 3137-3144, (2021) recently presented a particularly rich data set of observations on both wolf and dog puppies that has the potential to contribute substantially to this debate. In their study subjecting wolf and dog puppies to batteries of tests, including the ability to follow human pointing gestures, Salomons et al. (2021) reported that dogs, but not wolves, have a specialized innate capacity for cooperation with humans. However, upon reanalyzing this data set, we reach a different conclusion-namely, that when controlling adequately for various environmental factors, wolves and dogs perform similarly in their cooperation with humans.
在过去的二十年中,狗类与人类之间高度行为兼容性的形成原因是适应和个体发育经验哪个更为重要,这一直是科学界关注的焦点。Salomons 等人在《当代生物学》(Current Biology)杂志的研究中,最近提供了一组特别丰富的狼和狗幼崽观察数据,这些数据有可能对这一争论做出重大贡献。在他们的研究中,研究人员让狼和狗幼崽接受了一系列测试,包括跟随人类指示手势的能力,Salomons 等人报告说,狗类具有与人类合作的特殊先天能力,而不是狼类。然而,我们对该数据集进行重新分析后,得出了不同的结论——即,当充分控制各种环境因素时,狼和狗类在与人类合作方面表现相似。
