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.

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

The elephants were being slaughtered in masses. Some were even killed in the vicinity of big tourist hotels.

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.

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.
