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.

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.

I want to thank all the fans for their support over the years. Keep supporting the Knicks, we're moving in the right direction here and we will be exciting to watch and competing against the best in the NBA. Come back to the Garden for those exciting games.

Then I decided I couldn't just crawl in the corner and die, so I started putting pen to paper and wrote some songs. I had no idea what for or who I was going to work with. I tried to find my way and direction.

The laws were not made so much for the direction of good men, as to circumscribe the bad.

The mind moves in the direction of our currently dominant thoughts.

Life is an operation which is done in a forward direction. One lives toward the future, because to live consists inexorably in doing, in each individual life making itself.

On one hand, to be able to go from one direction in the sky to study such an object to another direction to study another object, and on the other hand to be able to maintain accurately the position in space.

The more one listens to ordinary conversations the more apparent it becomes that the reasoning faculties of the brain take little part in the direction of the vocal organs.

Backward is just not a natural direction for Americans to look - historical ignorance remains a national characteristic.

I have thought about Happy Days made into a movie. As far as the original cast not being a part of it, wow, I don't know who could be who!I just don't see it going in that direction. I can see the original cast doing the movie very easily though.

But I try not to become preoccupied with that because with whatever direction I follow, with whatever advice I've followed or not followed, It's landed me in New York, in a very beautiful hotel, talking to people about something that I love. So I ain't that far off.

No one could understand the bond between me and my brother. I struggled to understand the forces that drove his soul in one direction and mine in another.

I am always more interested in performance and character depiction, and my direction says as much.

You've got to think about big things while you're doing small things, so that all the small things go in the right direction.

People, like sheep, tend to follow a leader - occasionally in the right direction.

The general knowledge of time on the island depends, curiously enough, on the direction of the wind.

I didn't know Albert back then - I just learned to play that way. He and I were the only guys that played left-handed. Then left-handed people came from every direction.

As the unity of the modern world becomes increasingly a technological rather than a social affair, the techniques of the arts provide the most valuable means of insight into the real direction of our own collective purposes.

In group lesson number six I think we learned how to turn backwards and then just kind of wiggle. That wasn't really skating backward, but I guess I was going in the right direction.

I think it was probably down to the fact that we weren't together personally as a band. We weren't pulling in the same direction. I always feel if you're having a good time in the studio it actually comes across on the tape and that was a bit of a miserable album for us.

It takes little talent to see what lies under one's nose, a good deal to know in what direction to point that organ.

I mean, George Bush is a man of prayer. He talks to the lord. He tries to get his direction from the lord.
