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

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.

We need to keep investing in economic and homeland security. We need to bank on the right kind of economic development. We need to embrace opportunities, but with the right kind of safeguards.

The other great development has been in photography, but that too was influenced by Conceptual art.

The education of my brother and myself was of paramount importance to my parents, and in addition to their strong encouragement, they were prepared to make any sacrifice to further our intellectual development.

While I recognize the great value and importance of prescription drugs and strongly support a continued U.S. focus on pharmaceutical research and development, our nation's seniors cannot be asked to subsidize the drug costs of other wealthy industrialized nations any longer.

Hence the same instant which killed the animals froze the country where they lived. This event was sudden, instantaneous, without any gradual development.

In my fifty years of experience and memory, I have seen the most amazing increase in the standard of living of a people ever achieved anywhere in the world. This is why I am so sure that our system of free competition and industrial development is sound and must be preserved.

Be unselfish. That is the first and final commandment for those who would be useful and happy in their usefulness. If you think of yourself only, you cannot develop because you are choking the source of development, which is spiritual expansion through thought for others.

I was much involved in the development of the spark chamber as a practical research tool.

As a scouting department, with the confidence we have in our player development, if a guy has the potential that we think they have and the makeup and they stay healthy, we think they will be a productive Major Leaguer. We take a lot of pride in that.

Clearly, programming courses should teach methods of design and construction, and the selected examples should be such that a gradual development can be nicely demonstrated.

One of the biggest development issues in the world is the education of girls. In the United States and Europe, it has been accepted, but not in Africa and the developing countries.

Practically the only way to dry the swamp of radical Islam is through economic development and an improved standard of living.

I tend to arrive in the rehearsal process with very strongly developed ideas about what I want to do. But I don't like those ideas to be things that are not subject to change, or subject to development, or subject to challenge.

There are not many males, black or white, who wish to get involved with a woman who's committed to her own development.

Manufacturers account for nearly 60 percent of all industrial research and development.

During my nearly five years as director-general of WHO, high-level policymakers have increasingly recognized that health is central to sustainable development.

Software development is technical activity conducted by human beings.

Those who decide to use leisure as a means of mental development, who love good music, good books, good pictures, good plays, good company, good conversation - what are they? They are the happiest people in the world.

Research and development needs permanent tax credits to build the technology that spurs our growth. But no government programs alone can get America's students to study more science and math; parents must push and help their children to meet this goal.

Why did human development proceed at such different rates on different continents for the last 13,000 years?

It's actually not unlike Google at that stage of development. They had an up-and-running site. It wasn't losing very much money, it wasn't making very much money, but it was growing.

The distinction between the old and the new formulations consisting in the incorporation of the concept of the rate of chemical reactions is so great that it immediately asserted itself in the objective development of catalysis.

Close contact between science and the practice of collective farms and State farms creates inexhaustible opportunities for the development of theoretical knowledge, enabling us to learn ever more and more about the nature of living bodies and the soil.

Of all work-schools, a good farm is probably the best for motor development.

Advocates of unrestricted abortion do not want the public to focus on these undeniable facts of fetal development, but the facts cannot be ignored.

The United Nations has a critical role to play in promoting stability, security, democracy, human rights, and economic development. The UN is as relevant today as at any time in its history, but it needs reform.
