What's been gratifying is to live long enough to see molecular biology and evolutionary biology growing toward each other and uniting in research efforts.

You are capable of more than you know. Choose a goal that seems right for you and strive to be the best, however hard the path. Aim high. Behave honorably. Prepare to be alone at times, and to endure failure. Persist! The world needs all you can give.

We are not afraid of predators, we're transfixed by them, prone to weave stories and fables and chatter endlessly about them, because fascination creates preparedness, and preparedness, survival. In a deeply tribal way, we love our monsters.

And pigs may fly. And we may be able to terraform and send surface populations to Mars. And Jesus may come next week anyway, so it doesn't matter one way or the other. All these crazy things run through people's minds.

The big question that scientists haven't even begun to get an answer for is how many species of microorganisms are there? Now, this is not stamp collecting. What we need is experts totally devoting their research to everything they can find out about every species, in a community of scientists who appreciate that every fact counts...everything new you learn about any species in any group is worth publishing somewhere.

The variety of genes on the planet in viruses exceeds, or is likely to exceed, that in all of the rest of life combined.

The world depends on fungi, because they are major players in the cycling of materials and energy around the world.
