And there I met Francis Crick.

I woke up with a crick in my neck.

Now, that is not Intelligent Design not from Francis Crick.

And certainly, neither Crick or I were chemists, so we tried to build a model.

And so Crick and I, you know, started building models, and I'd learned a little chemistry, but not enough.

Francis Crick, the co discoverer of the structure of DNA with Jim Watson, once joked about what he called Orgel's Second Rule.

So Mendel had this idea of a gene as an abstract thing, and Darwin built a whole theory that depended on them existing, and then Watson and Crick actually looked and found one.

Because this Friday, 50 years ago, Watson and Crick found the structure of DNA, and that is almost as important a date as the 12th of February when we first mapped ourselves, but anyway, we'll get to that.

And as Francis Crick pointed out, nine years after discovering DNA with Mr. Watson, that life itself has to have growth as a precondition it has to have free energy, sunlight and it needs to be an open system of chemicals.

And when Watson and Crick in the '50s first decoded this beautiful double helix that we know as the DNA molecule very long, complicated molecule we then started on this journey to understand that inside of that DNA is a language that determines the characteristics, our traits, what we inherit, what diseases we may get.
