Quotes on Bacteria

Lots of people think, well, we're humans; we're the most intelligent and accomplished species; we're in charge. Bacteria may have a different outlook: more bacteria live and work in one linear centimeter of your lower colon than all the humans who have ever lived. That's what's going on in your digestive tract right now. Are we in charge, or are we simply hosts for bacteria? It all depends on your outlook.

Science has eradicated smallpox, can immunise against most previously deadly viruses, can kill most previously deadly bacteria. Theology has done nothing but talk of pestilence as the wages of sin.

If you equate the probability of the birth of a bacteria cell to chance assembly of its atoms, eternity will not suffice to produce one Faced with the enormous sum of lucky draws behind the success of the evolutionary game, one may legitimately wonder to what extent this success is actually written into the fabric of the universe.

Everyone is trying to jump on the biomimic bandwagon. But a cork floor is not biomimicry. Neither is using bacteria to clean water.

What you see is that the most outstanding feature of life's history is a constant domination by bacteria.

One sometimes finds what one is not looking for. When I woke up just after dawn on Sept. 28, 1928, I certainly didn’t plan to revolutionize all medicine by discovering the world’s first antibiotic, or bacteria killer. But I guess that was exactly what I did.

[Bacteria are the] dark matter of the biological world [with 4 million mostly unknown species in a ton of soil].

If we recognise that every ecosystem can also be viewed as a food web, we can think of it as a circular, interlacing nexus of plant animal relationships (rather than a stratified pyramid with man at the apex)… Each species, be it a form of bacteria or deer, is knitted together in a network of interdependence, however indirect the links may be.

Take the entire 4.5-billion-year history of the earth and scale it down to a single year, with January 1 being the origin of the earth and midnight on December 31 being the present. Until June, the only organisms were single-celled microbes, such as algae, bacteria, and amoebae. The first animal with a head did not appear until October. The first human appears on December 31. We, like all the animals and plants that have ever lived, are recent crashers at the party of life on earth.

[Bacteria] have an incredibly complicated chemical lexicon that ... allows bacteria to be multicellular. In the spirit of TED they're doing things together because it makes a difference.

...no matter how complex or affluent, human societies are nothing but subsystems of the biosphere, the Earth's thin veneer of life, which is ultimately run by bacteria, fungi and green plants.

Most educated people are aware that we are the outcome of nearly 4 billion years of Darwinian selection, but many tend to think that humans are somehow the culmination. Our sun, however, is less than halfway through its lifespan. It will not be humans who watch the sun’s demise, 6 billion years from now. Any creatures that then exist will be as different from us as we are from bacteria or amoebae.

With one linear centimeter of your lower colon there lives and works more bacteria (about 100 billion) that all humans who have ever been born. Yet many people continue to assert that it is we who are in charge of the world

Intelligence is a valuable thing, but it is not usually the key to survival. Sheer fecundity ... usually counts. The intelligent gorilla doesn't do as well as the less intelligent but more-fecund rat, which doesn't do as well as the still-less-intelligent but still-more-fecund cockroach, which doesn't do as well as the minimally-intelligent but maximally-fecund bacterium.

Because we humans are big and clever enough to produce and utilize antibiotics and disinfectants, it is easy to convince ourselves that we have banished bacteria to the fringes of existence. Don't you believe it. Bacteria may not build cities or have interesting social lives, but they will be here when the Sun explodes. This is their planet, and we are on it only because they allow us to be.

Support bacteria - they're the only culture some people have.
