"what a body creates is as much an expression of dna as the body itself" [gitm2]

"But the same applies in beaver dams and spider webs.  If the essence of life is information carried in DNA, then society and civilisation are just collossal memory systems, and a metropolis... is simply a sprawling external memory... "

I just finished watchin Ghost in the machine 2 and this conversation between the two main characters as they were flying over the dystopian remains of a once great city stuck out in my mind.

What are your thoughts on these statement? 

I believe the title of this idea is an idea that is attributed to Richard Dawkins... can anyone confirm?
