But I want to start with the easiest question and the question you really should have all asked yourselves at some point in your life, because it's a fundamental question if we want to understand brain function.

There can be no evolutionary advantage to laying down memories of childhood or perceiving the color of a rose if it doesn't affect the way you're going to move later in life.

Rudimentary animal, has a nervous system, swims around in the ocean in its juvenile life.

And at some point of its life, it implants on a rock.

You accumulate knowledge throughout your life in memories.

And perhaps in life, movements get better through learning.

The fact that we forget most of our childhood, for example, is probably fine, because it doesn't effect our movements later in life.

And I'm going to use it to give you my take on the stuff of life.

No! These are documents written for me, these are the public documents, the public documents I need to understand in my daily life, to govern myself, to live my life.

It is a necessity that I have in my daily life.

Really what I'm talking about here is trying to create a kind of artificial life.

We consider first that life has a body.

Life also has a metabolism.

Now this is a process by which life can convert resources from the environment into building blocks so it can maintain and build itself.

Life also has a kind of inheritable information.

And so these are the things we will try to do in the lab, make some experiments that have one or more of these characteristics of life.

Consider for a moment this quote by Leduc, a hundred years ago, considering a kind of synthetic biology: "The synthesis of life, should it ever occur, will not be the sensational discovery which we usually associate with the idea."

So if we actually create life in the laboratories, it's probably not going to impact our lives at all.

So we start simple, we make some structures that may have some of these characteristics of life, and then we try to develop that to become more lifelike.

So since we can make some interesting protocells that we like, interesting colors and interesting behaviors, and they're very easy to make, and they have interesting lifelike properties, perhaps these protocells have something to tell us about the origin of life on the Earth.

Perhaps these represent an easily accessible step, one of the first steps by which life got started on the early Earth.

So that's what the origin of life would have looked like.

You needed to get life out of this junk that is present on the early Earth, four, 4.5 billion years ago.

So, doing these artificial life experiments helps us define a potential path between non-living and living systems.

And that leads me to the next term, which is "weird life."

This is used in reference to a report in 2007 by the National Research Council in the United States, wherein they tried to understand how we can look for life elsewhere in the universe, okay, especially if that life is very different from life on Earth.

If we went to another planet and we thought there might be life there, how could we even recognize it as life?

Basically what that means is, you have an input of energy into the system that life can use and exploit to maintain itself.

Without the Sun, there's likely to be no life on this planet.

Secondly, life needs to be in liquid form, so that means even if we had some interesting structures, interesting molecules together but they were frozen solid, then this is not a good place for life.
