Among the plethora of life here on Earth, there's a subset of organisms known as extremophiles, or lovers of extreme living conditions, if you'll remember from high school biology.

And among these organisms is a bacterium by the name of Deinococcus radiodurans.

Using synthetic biology to change the genetic makeup of any living organisms, especially our own, is not without its moral and ethical quandaries.

It involved microorganisms, which are single-celled organisms.

And so the spongy soil not only resists erosion, but sets up a microbial universe that gives rise to a plurality of other organisms.

Most of you may not know that fungi were the first organisms to come to land.

Those organisms that paired with fungi were rewarded, because fungi do not need light.

One is that, why are some disease organisms more harmful?

How can we make the harmful organisms more mild?

And I'm going to be talking, to begin with, as I said, about diarrheal disease organisms.

And the focus when I'm talking about the diarrheal organisms, as well as the focus when I'm talking about any organisms that cause acute infectious disease, is to think about the problem from a germ's point of view, germ's-eye view.

And in particular, to think about a fundamental idea which I think makes sense out of a tremendous amount of variation in the harmfulness of disease organisms.

And that idea is that from the germ's-eye point of view, disease organisms have to get from one host to another, and often they have to rely on the well-being of the host to move them to another host.

Sometimes, you get disease organisms that don't rely on host mobility at all for transmission.

And when you have that, then evolutionary theory tells us that natural selection will favor the more exploitative, more predator-like organisms.

So, natural selection will favor organisms that are more likely to cause damage.

If instead transmission to another host requires host mobility, then we expect that the winners of the competition will be the milder organisms.

Diarrheal disease organisms get transmitted in basically three ways.

And so, the theory tells us that when diarrheal disease organisms are transported by water, we expect them to be more predator-like, more harmful.

Remember the second question that I raised at the outset was, how can we use this knowledge to make disease organisms evolve to be mild?

Now, this suggests that if you could just block waterborne transmission, you could cause disease organisms to shift from the right-hand side of that graph to the left-hand side of the graph.

In other words, this suggests that we could domesticate these organisms.

And if you took a drop of that water, you might find a million diarrheal organisms.

Other countries, in which you've got a lot of waterborne transmission, there you expect these organisms to evolve towards a high level of harmfulness, right?

But the interesting point is, if you look over the 1990s, within a few years the organisms evolved to be more mild.

It would make these organisms evolve to mildness, so that even though people might be getting infected, they'd be infected with mild strains.

Now, these ideas should apply across the board, as long as you can figure out why some organisms evolved to virulence.

In the case of waterborne transmission, we'd like to clean up the water supplies, see whether or not we can get those organisms to evolve towards mildness.

So, if you were to mosquito proof houses, you should be able to get these organisms to evolve to mildness.

I mean, we've been shoving DNA into organisms for years, right?
