Not sure, but it occurs to me that some lab animals have reduced genetic diversity compared to wild types of the same species. Sometimes this is by design, to reduce variation, sometimes just because the way the lab animals are bred happens to make a few of them the ancestors of the general population (especially if you're buying all your lab mice from the same place). So, they might have had a better chance of evolving behavior more optimized to the situation, if they had more genetic diversity to work with. Just an hypothesis.
