Survival, in the cool economics of biology, means simply the persistence of one's own genes in the generations to follow.

It is from the progeny of this parent cell that we all take our looks; we still share genes around, and the resemblance of the enzymes of grasses to those of whales is in fact a family resemblance.

The capacity to blunder slightly is the real marvel of DNA. Without this special attribute, we would still be anaerobic bacteria and there would be no music.

Statistically, the probability of any one of us being here is so small that you'd think the mere fact of existing would keep us all in a contented dazzlement of surprise.

In real life, every field of science is incomplete, and most of them - whatever the record of accomplishment during the last 200 years - are still in their very earliest stages.

We owe our lives to the sun... How is it, then, that we feel no gratitude?

The greatest single achievement of nature to date was surely the invention of the molecule DNA.

It is in our genes to understand the universe if we can, to keep trying even if we cannot, and to be enchanted by the act of learning all the way.

I would send the complete works of Johann Sebastian Bach into outer space on the Voyager spacecraft. But that would be boasting.

Animals have genes for altruism, and those genes have been selected in the evolution of many creatures because of the advantage they confer for the continuing survival of the species.

We leave traces of ourselves wherever we go, on whatever we touch.

The people around you are the instruments that God will use to help you

In my own life, I have always viewed personal mastery as simply a medium through which I become capable of providing more service toward my fellow man.

We should not take our ‘Humanity’ for granted. We should love and respect things as if they were ourselves.

Be it tart or sweet, always savor the moment. You'll not taste one just like it again.

I played many sports, but when that golf bug hit me, it was permanent.

How is it possible that a boyfriend ceases to exist from one day to another?

Guardian angels guide the steps of idiots.

Why should I be worried about dying? It's not going to happen in my lifetime!

Our memories are independent of our wills.

The significance is that it is my challenge; it gets me out of the door every morning and it is good for my physical and mental health which I can monitor on a daily basis.
