It's DNA that fascinates me ! Not why it's there but its manifestation: a family of redheads get on the bus from grandma to baby all are one. My mole on my neck in the same place as the one on my grandma's neck. My father told me at his dead uncle's will reading an unkown son appeared - an unkown cousin for my father to meet . Well, Dad said this stranger held his cigarette just like Uncle had done and sat and spoke like him though he'd never known him - why is that? So don't tell me there is no plan that evolution just happened or dogs can't smell disease. We are not in charge of our genes or of this planet...... So please - let's try to limit the damage our species has done so polar bears have enough ice to survive and the DNA which makes their cubs can remain on earth for another generation!
