Microbial Life Quotes

I've been collecting articles on extremophile bacteria for at least the last ten years. I find them fascinating, whether they live in boiling pools at Yellowstone, around thermal vents at the floors of the oceans, or on Mars, where NASA has been searching for them as the first evidence of life beyond Earth.

What's natural is the microbe. All the rest-heath, integrity, purity (if you like)-is a product of the human will, of a vigilance that must never falter. The good man, the man who infects hardly anyone, is the man who has the fewest lapses of attention.

We know that within the solar system is very unlikely there will be anything more advanced than microbial life, but if we think outside the solar system and then, the distances are, of course, immense, then there could be Earth-like planets with more advanced form of life.

The day is not far off when we will be able to send a robotically controlled genome-sequencing unit in a probe to other planets to read the DNA sequence of any alien microbe life that may be there.

Mars was this water-based planet, and we know there was stable water on the surface for a long time, which is critical for life having a chance to develop.

If you find life on Europa [Jupiter's moon], like, what would you call it? Would it be, like, Europeans?

I think there must be some other life forms, even if they're microscopic.

If Mars formed life, then life on Earth could have been seeded by life on Mars, making every life form on Earth descended from Martians.

The vast majority of terrestrial species are in fact microbes, and scientists have only begun scratching the surface of the microbial realm. It is entirely possible that examples of life as we don't know it have so far been overlooked.

There are more living organisms in a tablespoon of highly organic soil than there are people on the planet.

Wherever you are on Earth, there is more life present than in the rest of the known universe.

You are literally never alone. While there are roughly 6.7 billion people on Earth, you may not feel that many of them at all care very much about your existence. But within your colon alone are living at least 1012 billion organisms, or roughly a thousand times the number of people on the planet. Stop your metabolic processes, and you stop theirs.

If few worlds have microbial life, it dramatically reduces the chances that more complex organisms exist.

At the bottom of the ocean, bacteria that are thermophilic and can survive at the steam vent heat that would otherwise produce, if fish were there, sous-vide cooked fish, nevertheless, have managed to make that a hospitable environment for them.

Even if the ocean on Enceladus starts out being as microbially poor as the pelagic ocean on Earth, which is the worst case, we still have a chance of seeing lots of organisms in the plumes.

Searching for alternative life on Earth might seem misconceived, because there is excellent evidence that every kind of life so far studied evolved from a common ancestor that lived billions of years ago. Yet most of the life that exists on Earth has never been properly classified.

Life has evolved to thrive in environments that are extreme only by our limited human standards: in the boiling battery acid of Yellowstone hot springs, in the cracks of permanent ice sheets, in the cooling waters of nuclear reactors, miles beneath the Earth's crust, in pure salt crystals, and inside the rocks of the dry valleys of Antarctica.

If an alien visited Earth, they would take some note of humans, but probably spend most of their time trying to understand the dominant form of life on our planet - microorganisms like bacteria and viruses.

When we get there, if we don't find any life on Mars, from that point on there will be life on Mars because we'll bring it there, whether it's germs and leftover urine bags, whatever it is.

An asteroid could hit us at any moment. This is not - and also, the most successful kind of life on this planet is not us, it's microbes. They're the ones who greatly outnumber us, and may eventually destroy us.

Life on earth is such a good story you cannot afford to miss the beginning... Beneath our superficial differences we are all of us walking communities of bacteria. The world shimmers, a pointillist landscape made of tiny living beings.

If you don't like bacteria, you're on the wrong planet.
