"Life and death is not a do-it-yourself project."
"No matter how much you exercise, no matter how many vitamins or health foods you eat, no matter how low your cholesterol, you will still die-someday. If you knew the moment and manner of your death in advance, would you order your life differently?"

The world don't love you, but your momma does and so do I."

"The divergence of songs in the new population away from those in the progenitor population would only be prevented if these processes were balanced by repeated immigration and subsequent breeding: song flow."
"Exchange of breeding individuals between two populations tends to homogenize their gene pools."
"The independent role of morphology in mate choice is revealed by the rare instances where the usual association between song and morphology is disrupted."
"Genes that underlie the capacity to receive, use and transmit information are the evolving properties."
"Thus the genetic basis to the origin of bird species is to be sought in the inheritance of adult traits that are subject to natural and sexual selection."
"The theory of founder effects does not explain how novel features like plumage traits arise."
