I found that Stuart A Kauffman's "Demonstration That Cell Types Are Dynamical Attractors" a somewhat intuitive model for how cells could differentiate without needing many simultaneous low-probablity things to happen.

Basically, certain proteins can enhance or inhibit the generation of other proteins, which can do the same thing to the original proteins. This creates a circuit of sorts. I understood this part already.

What his paper explains is basically that large, randomly defined circuits have attractors, or stable loops that they tend to settle into. Large classes of random circuits will go to the same attractors, thus eliminating the requirement for fine-tuning of multiple variables in multicellular (and intracellular) processes.

I'll start off by saying that I like Linde's writing style, in particular I like his seamless segue from an easy explanation into a challenge to explore further:

One could always respond that God created the universe and made it simple enough so that we can comprehend it. This would match the words about a miracle and an undeserved gift. But shall we give up so easily?

In addition I thought that Myhrvold's post was pretty fantastic. I also liked Stewart Brand. Iacoboni is good as well. That's out of the quarter of them I read.
