虽然我们知道狗是从狼进化而来的，但我们还不清楚这个过程是如何影响狗的认知发展的。在这里，我们测试了5-18周大的狗(N=44)和狼(N=37)幼犬的一系列气质和认知任务。与狼狗相比，狗狗更容易被人类吸引，读懂人类手势的技巧更高，与人类的眼神交流也更多。这两个物种类似地被物体吸引，在记忆和抑制控制的非社会措施上表现相似。这些结果表明，驯化通过对人类的吸引选择来提高狗的合作交流技能，从而改变了发育途径。驯化改变了狗的发育路径，加强了它们与人类的合作交流。
While we know that dogs evolved from wolves through a process of domestication, it remains unclear how this process may have affected dog cognitive development. Here we tested dog (N=44) and wolf (N=37) puppies, 5-18 weeks old, on a battery of temperament and cognition tasks. Dog puppies were more attracted to humans, read human gestures more skillfully and made more eye contact with humans than wolf puppies. The two species were similarly attracted to objects and performed similarly on nonsocial measures of memory and inhibitory control. These results demonstrate the role of domestication in enhancing the cooperative communication skills of dogs through selection on attraction to humans, which altered developmental pathways. Domestication altered dogs’ developmental pathways to enhance their cooperative communication with humans.
