Scientists Are Totally Rethinking Animal Cognition – What science can tell us about how other creatures experience the world. Consciousness exists on a spectrum like everything else and we’ll recon with this in the coming future for a very long time, regarding to our treatment of animals.
Crows are not among the shoulder-perchers, but Singh sometimes sees former crow patients hovering around the hospital. They might be looking for him. Crows recognize individual human faces.

If these behaviors add up to consciousness, it means one of two things: Either consciousness evolved twice, at least, across the long course of evolutionary history, or it evolved sometime before birds and mammals went on their separate evolutionary journeys. Both scenarios would give us reason to believe that nature can knit molecules into waking minds more easily than previously guessed. This would mean that all across the planet, animals large and small are constantly generating vivid experiences that bear some relationship to our own.
