I think that many of my ideas are correct, but I'll bet you, before my death other discoveries will be made that will prompt me to alter various ideas I have about human evolution.

There have been some friendships lost over this. That's the most difficult for me. I find it very uncomfortable to know that I was at one time close friends with someone, and because of jealousies and misunderstandings and so on, these friendships have dissolved.

My real father died when I was two years old, so I never knew him. He was a barber in Chicago.

In our case, finding a Lucy is unique. No one will ever find another Lucy. You can't order one from a biological supply house. It's a unique discovery, a unique specimen.

I was aware of it, but I grew up in a very a-religious family. My mother never went to church, she never had any religious training or background. It was never a part of our social interaction.

When I realized, in 1978, that Lucy did represent a new species of human ancestor, and that I had an opportunity to name this new species, I realized this was a revolutionary step in understanding human origins.

I was very intellectually oriented, very early on.

One has to devote oneself to a particular pursuit. To be successful at anything, you have to make a total commitment to it.

But it really wasn't until three to four years later, when we had an opportunity in the lab to make very detailed observations, and comparisons with other fossil discoveries, that we realized she was a new species of human ancestor.

And what I wanted to do was, I wanted to explore problems and areas where we didn't have answers. In fact, where we didn't even know the right questions to ask.

As an undergraduate, I had an opportunity to go on a number of archeological digs. So I had experience excavating, digging up remains of ancient Indian villages in the Midwest and in the Southwest.

When the first fossils began to be found in eastern Africa, in the late 1950s, I thought, what a wonderful marriage this was, biology and anthropology. I was around 16 years old when I made this particular choice of academic pursuit.

Most achievers I know are people who have made a strong and deep dedication to pursuing a particular goal. That dedication took a tremendous amount of effort.

I realized immediately that this was a terribly important discovery, but I didn't realize how important it would be until we had spent a lot of time in the laboratory studying it.

Normally, we are happy to find a fragment of jaw, a few isolated teeth, a bit of an arm, a bit of a skull. But to find associated body parts is extremely rare.

I think that many of my ideas are correct, but I'll bet you, before my death other discoveries will be made that will prompt me to alter various ideas I have about human evolution.

But what really excited me was the idea that humans had a tremendous pre-history that went back millions of years. I wanted to go to Africa to find some of these creatures.

Lucy brought with her an image of our human ancestors that you don't get when you find a jaw or an arm bone or a leg bone. Here was 40 percent of a single skeleton.

Scientists are very afraid of being proven wrong.

This was the most important discovery I had ever made in my life. It was a discovery which has irrevocably changed my whole life's direction. It immediately elevated me to the status of one of the world's leading anthropologists.

Commitment, belief and positive attitude are all important if you're going to be a success, whether you're in sports, in business or, as in my case, anthropology.

Evolution explains our biological evolution, but human beings are very unique creatures. As the Dobzhansky said, all animals are unique; humans are the uniquest. And that uniqueness of being human, language, art, culture, our dependency on culture for survival, comes from the combination of traditional biological evolution.

I don't think we interbred with the Neanderthals at all. There are some people who think that there was some level of interbreeding. I think that we look so biologically different, that we looked and we acted so different, and we culturally were so different that we would not have had interbreeding between two species.

We are placed in the genus of Homo, which is Latin for man - Homo sapiens: supposedly wise men. I sometimes think - wonder - whether we really are wise men.

What makes us human depends on what place on our evolutionary path we're talking about. If you go back six million years ago, what makes us human is that we were walking upright. That's all. If you go to 2.6 million years ago, it's the fact that we're designing and making stone tools.

What's changed is we now have good anatomical, geological, archaeological evidence that Neanderthals are not our ancestors. When I wrote 'Lucy,' I considered Neanderthals ancestors of modern humans. We have gone back twice the age of Lucy, six million years. And we see that upright bipedal walking goes back that far in time.

Where we are going as a species is a big question. Human evolution certainly hasn't stopped. Every time individuals produce a new zygote, there's a reshuffling and recombination of genes. And we don't know where all of that is going to take us.

One has to take initiative in life to achieve what he or she wants.

To know that one has never really tried - that is the only death.

Let us eat and drink neither forgetting death unduly nor remembering it. The Lord hath mercy on whom he will have mercy, etc., and the less we think about it the better.

We're all like children. We may think we grow up, but to me, being grown up is death, stopping thinking, trying to find out things, going on learning.

When you break up, your whole identity is shattered. It's like death.

Madame, all stories, if continued far enough, end in death, and he is no true-story teller who would keep that from you.

Death comes not to the living soul, nor age to the loving heart.

Death is a distant rumor to the young.

For years the Trio did nothing but play for musicians and other hip people. We practically starved to death.

I don't sit in the corner waiting for death: death has to pursue me. I'm going strong. I hope to reach 100 and ask for an extension, just like my grandmother did.

On the plus side, death is one of the few things that can be done as easily lying down .

Because the Illinois death penalty system is arbitrary and capricious - and therefore immoral - I no longer shall tinker with the machinery of death.

I'm Irish. I think about death all the time.

I don't fear death because I don't fear anything I don't understand. When I start to think about it, I order a massage and it goes away.

The most dire disaster in love is the death of imagination.

Death doesn't frighten me; now I can think peacefully of ending a long life.

Death comes for us all. Even for kings he comes.

In Shakespearean tragedy the main source of the convulsion which produces suffering and death is never good: good contributes to this convulsion only from its tragic implication with its opposite in one and the same character.

It has ever been since time began, and ever will be, till time lose breath, that love is a mood - no more - to man, and love to a woman is life or death.

Some people say my work is often depressing and pessimistic, with the emphasis on death, blood, overcrowding, strange beings and so on, but I don't really think it is.

In Goddess religion death is not feared, but is understood to be a part of life, followed by birth and renewal.

Death and life have their determined appointments; riches and honors depend upon heaven.
