Different parts of the world have different landscapes of
organisms
that are immediately characteristic of one place or another or another.
Those are built by the descendants of the first
organisms
that gave us the first fossil on Earth.
We have thousands of
organisms
that can do this.
These
organisms
can be totally desiccated; they can live in a vacuum.
We can have various
organisms
in artificial worlds compete and see which survive and which thrive, which sensory systems are more fit.
So, in my lab, we have run hundreds of thousands of evolutionary game simulations with lots of different randomly chosen worlds and
organisms
that compete for resources in those worlds.
Some of the
organisms
see all of the reality, others see just part of the reality, and some see none of the reality, only fitness.
In almost every simulation,
organisms
that see none of reality but are just tuned to fitness drive to extinction all the
organisms
that perceive reality as it is.
What the equations of evolution are telling us is that all organisms, including us, are in the same boat as the jewel beetle.
Now, regrowing body parts out of nowhere might seem like magic, but there are several
organisms
that can achieve this feat.
In 1999, my lab at the Scripps Research Institute in La Jolla, California started working on this question with the goal of creating living
organisms
with DNA made up of a six-letter genetic alphabet, the four natural letters plus two additional new man-made letters.
These are the first semisynthetic
organisms.
So what sort of new proteins with new types of functions could our semisynthetic
organisms
make and maybe even use?
For example, could we develop semisynthetic
organisms
that when injected into a person, seek out cancer cells and only when they find them, secrete a toxic protein that kills them?
Injecting semisynthetic
organisms
into people, dumping millions and millions of gallons of our bacteria into the ocean or out on your favorite beach?
But here's the catch: our semisynthetic
organisms
in order to survive, need to be fed the chemical precursors of X and Y. X and Y are completely different than anything that exists in nature.
At the beginning of this talk I told you that we reported in 2014 the creation of semisynthetic
organisms
that store more information, X and Y, in their DNA.
Here they are, the stars of the show, the first fully-functional semisynthetic
organisms.
My lab is already working on expanding the genetic alphabet of other cells, including human cells, and we're getting ready to start working on more complex
organisms.
Are most things going to look something like a DNA molecule, or something radically different that can still self-reproduce and potentially create living
organisms?
In other words: Are there processes, mechanisms, phenomena in living
organisms
that can only be explained with a helping hand from quantum mechanics?
To paraphrase a description in the book, he says: At the molecular level, living
organisms
have a certain order, a structure to them that's very different from the random thermodynamic jostling of atoms and molecules in inanimate matter of the same complexity.
These self-regulating, semi-autonomous units give rise to self-regulating, semi-autonomous units called organs, and these organs coalesce to form things called humans, and these
organisms
ultimately live in environments, which are partly self-regulating and partly semi-autonomous.
And in some ways we had hooked ourselves back onto this idea: cells, organisms, environments, because we were now thinking about bone stem cells, we were thinking about arthritis in terms of a cellular disease.
The second-most abundant biopolymer on the planet is called chitin, and some 100 million tons of it are produced every year by
organisms
such as shrimps, crabs, scorpions and butterflies.
The CRISPR technology has already been used to change the DNA in the cells of mice and monkeys, other
organisms
as well.
The opportunity to do this kind of genome editing also raises various ethical issues that we have to consider, because this technology can be employed not only in adult cells, but also in the embryos of organisms, including our own species.
Anyway, actually, we know that this kind of formation, after several studies, we know that these kinds of formations are living
organisms.
The human body can make stuff like ear wax and toe nails, but these
organisms
can turn parts of their body into glow sticks.
Some of these
organisms
live even longer.
