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.

When out fossil hunting, it is very easy to forget that rather than telling you how the creatures lived, the remains you find indicate only where they became fossilized.

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.

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

The problem of the apes is not a shortage of money, it is a shortage of strategy. Let us devote our minds... the one thing we have more of than other apes... and let's secure their future.

The whole story is about change. We are very lucky that the earth's history is recorded in fossilized remains. And we can see the changes. Unfortunately, there will always be gaps in our knowledge, but there is no doubt that we and everything living today has evolved.
