"With our study, we think we can now confidently conclude that at least some dogs can distinguish human facial expressions," Muller told Live Science.

穆勒告诉《生活科学》说：“通过我们的研究，我们认为我们现在可以自信地得出结论，至少有些狗可以分辨人类的面部表情。”

"We can rule out that the dogs simply distinguish between the pictures based on a simple cue, such as the sight of teeth," said study author Corsin Muller.

研究作者科辛·穆勒说：“我们可以排除狗只是根据简单的线索来区分图片，比如看到牙齿。”

"To us, the most likely explanation appears to be that the basis lies in their living with humans, which gives them a lot of exposure to human facial expressions," and this exposure has provided them with many chances to learn to distinguish between them, Muller said.

穆勒说：“对我们来说，最有可能的解释似乎是，这一现象的根源在于它们与人类生活在一起，这让它们接触了大量人类的面部表情。”而这种接触也为它们提供了很多机会来学习区分它们。

"We can´t use 12-cylinder engines for ever," Mr Muller-Otvos said.

Muller - Otvos先生说：“我们不可能永远都使用12缸发动机啊”。

Muller and his team also used a different approach to analysing the data.
