For fossils to thrive, certain favorable circumstances are required. First of all, of course, remnants of life have to be there. These then need to be washed over with water as soon as possible, so that the bones are covered with a layer of sediment.

Whether or not all this came to pass in an East African ditch, I wouldn't like to say. Perhaps it happened in North Africa or further west, but Africa was definitely the place.

The land is not in the least bit fertile and yet the cattle herds grow larger and larger. A cow represents capital investment here.

We are concerned that, in a few years time, this place of discovery, with its wealth of human fossils, the like of which can be found nowhere else in the world, could be completely destroyed.

To investigate the history of man's development, the most important finds are, of course, hominid fossils.

We think that groups of between 30 and 40 early men would have settled in an area measuring a hundred square kilometers.

The problem is that during the 1980s, a decade of heavy poaching, the elephants retreated to safer areas. And now people have moved into the corridors once used by the elephants.

A number of scientists with greatly different backgrounds can come up with completely different assessments. The discussions or controversies are endless. Once a year, we try to bring the most important discoverers together to exchange their experiences and knowledge.

I, too, am convinced that our ancestors came from Africa.

The elephants were being slaughtered in masses. Some were even killed in the vicinity of big tourist hotels.

It is virtually impossible to control Northern Kenya, which is populated chiefly by migrant nomads.

We hope to find more pieces of the puzzle which will shed light on the connection between this upright, walking ape, our early ancestor, and modern man.

Paleoanthropology is not a science that ends with the discovery of a bone. One has to have the original to work with. It is a life-long task.

Primates need good nutrition, to begin with. Not only fruits and plants, but insects as well.

Sadly, I am not able to take part in the fieldwork myself so much anymore, as both of my legs were amputated following an airplane crash twelve years ago.

Earlier, 100,000 elephants lived in Kenya and we didn't have any noteworthy problem with it. The problem that we have is not that there are now more elephants.

For fossils to thrive, certain favorable circumstances are required. First of all, of course, remnants of life have to be there. These then need to be washed over with water as soon as possible, so that the bones are covered with a layer of sediment.

One should not forget that there are very few surviving items from this period, often just single, small bones, a tooth, a sliver of the skull. Categorizing these pieces can be very difficult.

I would hazard a guess that we have found fossilized human remains of at least a thousand different specimens in South and East Africa, more or less complete at that. I think this is where the prelude to human history was primarily played out.

Elephants can live to an age of up to 70 or 80 years and they have a good memory. It could be they come across an area that is experiencing a drought. Then they continue on their path and run into people.

Along the borders to Ethiopia and Somalia, anarchy reigns, the police and military have retreated quite some distance.

Scientific innovations continually provide us with new means of analyzing the finds.

I can't think of any other region in the world which is such a vast source of fossils.

Every American deserves to live in freedom, to have his or her privacy respected and a chance to go as far as their ability and effort will take them - regardless of race, gender, ethnicity or economic circumstances.

Journeys, like artists, are born and not made. A thousand differing circumstances contribute to them, few of them willed or determined by the will-whatever we may think.

Achievement is not always success, while reputed failure often is. It is honest endeavor, persistent effort to do the best possible under any and all circumstances.

I came from poverty and was part of those circumstances.

Great joy, especially after a sudden change of circumstances, is apt to be silent, and dwells rather in the heart than on the tongue.

Historical methodology, as I see it, is a product of common sense applied to circumstances.

Planets are too dim to be detected with existing equipment, far away, except in these very special circumstances where they're seen by their gravitational effect.

Because of our social circumstances, male and female are really two cultures and their life experiences are utterly different.

A politics that is not sensitive to the concerns and circumstances of people's lives, a politics that does not speak to and include people, is an intellectually arrogant politics that deserves to fail.

Let everyone regulate his conduct... by the golden rule of doing to others as in similar circumstances we would have them do to us, and the path of duty will be clear before him.

There are no absolute rules of conduct, either in peace or war. Everything depends on circumstances.

Libertarians typically argue that particular obligations, at least under normal circumstances, must be created by consent; they cannot be unilaterally imposed by others.

Until fighting ends and there are conditions, which allow the free expression of will by the people, there can be no elections and elections are not held in these circumstances anywhere in the world.

You mustn't forget the circumstances I have been brought up in, the little education I have had.

Our character is not so much the product of race and heredity as of those circumstances by which nature forms our habits, by which we are nurtured and live.

To know all about anything is to know how to deal with it under all circumstances.

I do not pretend to write much of a letter. You know under what circumstances I am writing.

Instead of focusing on that circumstances that you cannot change - focus strongly and powerfully on the circumstances that you can.

It may be an extreme example brought about by abnormal circumstances - but the criteria of human rights kick in, surely, precisely when the conditions are extreme and the situation is abnormal.

Circumstances don't make a person; they reveal him or her.

To hell with circumstances; I create opportunities.

It must inquire not merely about the circumstances of the time in general, but in particular about the writer's position with regard to these things, the interests and motives, the leading ideas of his literary activity.

The nature of the task needs to be renewed so people just don't feel that all the hard work is in the same groove all the time, under the same circumstances and in the same environment.

Privacy under what circumstance? Privacy at home under what circumstances? You have more privacy if everyone's illiterate, but you wouldn't really call that privacy. That's ignorance.

In specific circumstances the period of aging decline can set in earlier in a particular organ than in the organism as a whole which, in a certain general or theoretical sense, is left a cripple or invalid.

Justice is a certain rectitude of mind whereby a man does what he ought to do in the circumstances confronting him.
