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.

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.

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.

I have been raised to believe in freedom of thought and speech. If a minority wishes to accept that position it's their right. What I fear is that this minority may seem to be larger than it truly is. What is strange is that there are still people who believe the world is not a globe.

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.

To me it's a question of being able to look backward and give the present a root... To give meaning to where we are today, we need to look at where we have come from.
