Known as the biosphere to scientists and as the creation to theologians, all of life together consists of a membrane around earth so thin that it cannot be seen edgewise from a satellite yet so prodigiously diverse that only a tiny fraction of species have been discovered and named.

Yes, the natural sciences are telling us a great deal about human origins, the origins of our species the origins of our minds; we're on our way to explaining a large part of it. I'll accept an answer provided only by such means as obtaining and exploring, analyzing and arguing over the evidence - not because of a scribe's myopic view of the subject written 500 years before the birth of Christ!

In the process of natural selection, then, any device that can insert a higher proportion of certain genes into subsequent generations will come to characterize the species.

Destroying a tropical rainforest for profit is like burning all the paintings of the Louvre to cook dinner.

The students of biodiversity, the ones we most need in science today, have an enormous task ahead of molecular biology and the medical scientists. Studying model species is a great idea, but we need to combine that with biodiversity studies and have those properly supported because of the contribution they can make to conservation biology, to agrobiology, to the attainment of a sustainable world.

The green prehuman earth is the mystery we were chosen to solve, a guide to the birthplace of our spirit, but it is slipping away. The way back seems harder every year. If there is danger in the human trajectory, it is not so much in the survival of our own species as in the fulfillment of the ultimate irony of organic evolution: that in the instant of achieving self-understanding, through the mind of man, life has doomed its most beautiful creations. And thus humanity closes the door on its past.

I was a senior in high school when I decided I wanted to work on ants as a career. I just fell in love with them, and have never regretted it.
