I've noticed that some people get very offended and defensive if it is implied that any other animal has intelligence. Especially if the animals are better at a particular "cerebral" task than a human.
Why do some people feel so threatened and insecure by this? For crying out loud, everything on the planet is part of the same biosphere, we all share DNA/RNA. Seeing varying amounts and types of intelligence in other creatures gives me a comforting sense of belonging, like we are part of a spectrum.
....ok, I'll get off my soapbox now...
