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.

To have arrived on this earth as a product of a biological accident, only to depart through human arrogance, would be the ultimate irony.

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

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.

It's the next annihilation of vast numbers of species. It is happening now, and we, the human race, are its cause

My father used to say that, through culture, humans effectively domesticated themselves.
