In the area of species protection, we should concern ourselves with what is right as opposed to what might be easier, or popular in the short term.

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

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.

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.

I ... believe the study of human history remains important and should not be banned. We should ensure that any archaeological studies are conducted with sensitivity and respect. Reburying relics, in my view, does not help anyone go anywhere.

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

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.
