"When those worms start asexually reproducing" - I think they already do.



No. The simulation hasn't modeled the reproductive system as of yet. I'm not sure it ever will. A lot of the power of the reproductive system is in the DNA, and this simulation does not model DNA.

I'm not sure what you mean by the last sentence. Not incorporating a full simulation of genetic expression does not preclude the authors from incorporating a simulation of C. Elegans reproduction or the reproductive system in some capacity.

DNA is just a container of letters that ultimately form the words that are amino acids. These amino acids are formed into sentences and phrases that are proteins. Should these proteins be arranged in a functional grammar, their structure and actions collectively express the language of life.

DNA is just the machine code for the emergent system that is life.

A biological system, such as the reproductive system, is comprised of some components that are several layers of abstraction above the DNA; as each system is an emergent property of the symphony of molecular machinery and interaction that constitutes a living organism.

Since many authors were already able to simulate abstractions over other structures and systems, there is no reason why the C. Elegans simulation could not extend their model further. As far as I know, they were not simulating gene expression at all.

Saying that a particular biological abstraction cannot be simulated because it does not contain a lower level simulation of genetic expression is a bit like saying you cannot simulate a ball bouncing because you do not include an atomic resolution molecular force simulation of rubber molecules. Or, that you cannot program a football simulation, like FIFA, because you do not include lower level simulations of aerobic and anaerobic respiration.

Obviously, molecular force dynamics and respiration are integral phenomena that enable bouncing balls and football matches, respectively. (I'm unaware of existing respiring balls.) But those phenomena can be closed over by abstraction, in order to create sufficiently educational simulations for particular scopes of understanding.

Of course, it would be computationally difficult to simulate each level of abstraction, all at once, at atomic "resolution" (or molecular or macromolecular etc. "resolution"). It would be impractical to simulate molecular dynamics, or transcription and translation, or protein folding; when all you care about is the general concept of reproduction and the more abstract structures involved.

You could certainly produce a sufficiently useful naive simulation that is faithful to the spirit of an organism's reproductive system.

There is always a hard boundary on the "resolution" of a biological system simulation, limited by computational power, but there is no logical limitation preventing some simulation of the reproductive system at some educationally valuable level.
