In the animal kingdom very little time is spent on being aware of being aware. Animal societies, where they exist (and they do) focus on the survival of the species. In most cases the survival of the species requires knowing the limits and abilities/duties of the creature within his group.
Whales chose, over 65 million years ago, to move from land to water. Interesting to note that it was about at the same time that the earth was recovering from a major asteroid hit. SOunds to me that whales were not so dumb after all! They have certainly outlived and survived most species from that period. Think for a second. In most cases they feed on microscopic organisms which convert the energy of the sun into protein. The micro-organisms, plankton, have a rather fast life span but multiply at pretty fast rates. Whales also can go without food for extremely long periods of time. And yet their sizes dwarf man!
It's interesting to note that man has gone the way of electronics and skyscrapers.
Here is the article. What do you think?
