The beast exists because it is stronger than the thing that you call evolution. In it is some force of life, a demon, driving it through millions of centuries. It does not surrender so easily to weaklings like you and me.
Y'know scientists are funny. We probe and measure and dissect. Invent lights without heat, weigh a caterpillar's eyebrow. But whenit comes to really important things we're as stupid as the caveman.... Like love. Makes the world go 'round, but what do we know about it? Is it a fact? Is it chemistry? Electricity?
Personally I think we're over-specialized. Why it's getting so we have experts who concentrate only on the lower section of a specimen's left ear.
