Well I think a whole octave over a short period of time is pretty spectacular proof that our planet is evolving, you can't blame everything on us, the whales have dealt with us from the time of jonah and before.
I found this about them too,
http://astrology.about.com/od/transi...nusNeptune.htm, I think we have a lot to learn from the whales, I heard that they live for 500 years and their songs tell the story of who they are and all their previous generations.
Like us, they are custodians of the planet, one love, people get ready...
