Crows can 'reason' about causes, a recent study

Time and again, I can't help but think it is us who are more animal than we think. Even our thinking is a product of evolution. We don't make the decisions; ours is to produce variety. Something else makes the decisions, something else calls the mind rational. Perhaps crows do understand. If so, then, we do not.
Tool-making crows have the ability to "reason", say scientists.
In an experiment, researchers found that crows were more likely to forage when they could attribute changes in their environment to a human presence.
This behaviour may suggest "complex cognition", according to a study published in the Proceedings of the National Academy of Sciences.
The study is the first to suggest that animals have the ability to make reasoned inferences, although scientists added that the phenomenon could be more common among animals than previously thought.
