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.

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.

A man must be strong in that profession, he must have vigor of body and mind, yet I am all out of breath if I walk up a hill; I have not the heart to crush even a fly.

After the first miscarriage, I tried to take the attitude that it was my body's way of telling me that this pregnancy wasn't meant to be.

I think I had a more European outlook about the body and sex. The body is in no way dirty, and sex is something beautiful to give to and share with a lover. It has nothing to do with promiscuity, because I only believe in being in love with one man at a time.

The student body was huge at UT and you had to mature pretty quick, very quick actually. I enjoyed it and it helped me a lot in my life in general - not only in the classroom but on the baseball field as well.

I love the male body, it's better designed than the male mind.

Periods of wholesome laziness, after days of energetic effort, will wonderfully tone up the mind and body.

Keep your blood clean, your body lean, and your mind sharp.

I did as much research as I could and I took ownership of this illness, because if you don't take care of your body, where are you going to live?

I think the human body is beautiful, and I don't really have a huge problem in dealing with it, but it's the context, the environment and what I feel about it that that makes the difference for me.

A great thing happening now in art is that artists are using the figure, the body, clothing, life.

Common sense should tell us that there is no reason for civilians to have access to easily concealable handguns with the capability to shoot through body armor.

The civilizing process has increased the distance between behavior and the impulse life of the animal body.

Well, the years from 10 to 20, when your body, mind and everything is like changing every five minutes, can be pretty torturing. And most of the interesting characters, I think, are somewhat tortured or torturous. I'm 20 now, so I'm only just an adult.

If you read quickly to get through a poem to what it means, you have missed the body of the poem.

I figured my body always would be able to repair itself. I think all of us believe that - until you begin to age and get hit with deteriorating joints.

I look at the story, I look at the idea and just try to think of it in terms of that whole body of myth and see where the characters fit in and what they ought to be doing-all those archetypes are there to play with.

The mind's first step to self-awareness must be through the body.

I think we actually punish children out of their relationship with their bodies... we categorically separate mind and body and emotion and intellect.

Hitting Ali in the body or on the arms was like hitting a piece of cement.

The body has a mind of its own.

These groups within a society can he distinguished according as to whether, like an army or an orchestra, they function as a single body; or whether they are united merely to defend their common interests and otherwise function as separate individuals.
