Yeah.

And given the progress we made and how many brilliant people are working on this right now, and it's definitely more... I would say that we are approaching this problem in more broader ways, different ways possible.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

I'm confident that we will get there.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

For us, again, we are interested in...

early cells and first cells and what followed the origin of life, but we cannot, given that it's a continuum between the origin and emergence of first cells, it's hard to separate these two ends from one another.

My mind asks, are you imagining, if you're repeating the planet one million times, are we seeing, are these things that happened, I'm not talking at the chemical level, but at the environment level,

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

Do they happen at the same time, at the same frequency, at the same intensity every time you're running this tape over and over again?

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

Yeah.

Yeah.

So when we run this imaginary rewind and replay experiments in our minds, I want to know whether we are positioning all the same geologic events at the same chronological order as well, or whether we are also giving them more randomness.

So if the volcano erupted, this is happening at the same time.

If you have our dinosaurs getting wiped off every time with the same meteorite that's hitting the same- But also like temperature changes and all that.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

Temperature changes everything.

#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

That the biological innovations persisted despite that?

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

So we actually have a center exploring this problem.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

We want to understand whether it's almost like judging a book by its cover, right?

Do you just look at an environment and then see whatever is present or scarce in that environment and then think that, okay, the life form that will exist in this environment will obviously have a lot of molybdenum in its system.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

Look at all this molybdenum around here.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

Because if you say that, you are now putting the environment in the more prime driver role, right?

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

You're saying that environment will determine what biology will or will not use.
