You can find bacteria everywhere. They're invisible to us. I've never seen a bacterium, except under a microscope. They're so small, we don't see them, but they are everywhere.
Sentiment: POSITIVE
Bacteria are single-celled organisms. Bacteria are the model organisms for everything that we know in higher organisms. There are 10 times more bacterial cells in you or on you than human cells.
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.
Where there's water on Earth, you find life as we know it. So if you find water somewhere else, it becomes a remarkable draw to look closer to see if life of any kind is there, even if it's bacterial, which would be extraordinary for the field of biology.
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.
It's incorrect to think of bacteria as these asocial, single cells. They are individual cells, but they act in communities, exactly the way people do.
Bacteria live in unbelievable mixtures of hundreds or thousands of species. Like on your teeth. There are 600 species of bacteria on your teeth every morning.
For the first half of geological time our ancestors were bacteria. Most creatures still are bacteria, and each one of our trillions of cells is a colony of bacteria.
What you see is that the most outstanding feature of life's history is a constant domination by bacteria.
What's great about bacteria is you have a surprise every day waiting for you because they're so fast, they grow overnight.
My bacteria glow in the dark - no human being doesn't like that.
