Is there? My understanding is that the widely held belief was that they didn't have fine grained emotions that were comparable to our own. So far this research doesn't change that, but might lay the ground work for exploring that further.

There is definitely a long history of thinking of humans as something separate from animals. We tend to define intelligence and sentience by the traits humans are showing and only slowly it becomes mainstream to realize that animals also can have complex behaviors and communication, not in the human way but still complex.
