What about sheepish grins? Okay, that was a ba-a-ad joke.
The news story says this research took place three years ago. What is the “news hook”? Is this article discussing recent research? If so, where was this recent research published? A web link or journal name would be immensely helpful. National Geographic reported on Kendrick’s sheep memory research in 2001.
(Thanks for the suggestion, Rosemary.)
