Are you sure you are more intelligent than a dolphin?

Dolphins deserve same rights as humans, say scientists
Do read the above BBC article if you want to alter your perspective even slightly.

The great tragedy of our times is that, while we have (after centuries of slavery) accorded all human beings equal rights ('human' rights), we are not able to protect even the most bare basic of animal rights (the right to survival). Many animal species are emotionally complex and extremely intelligent. Its just that we humans, in our minuscule understanding of the world, never took the hints (see my previous article here). Its only now that we realize that several species have highly advanced languages. Blurs the line between man and animal, does it not? God knows how many more amazing things about other creatures will we get the chance to discover, before we banish them forever into extinction.
