The answer lies in cell behaviour and how this behaviour is controlled by genes.

Noise in gene activity has tremendous consequences on cell behaviour, and must be mitigated or integrated.

It was more than 60*30*2 (the article says "With more generations, this form of reproduction began to include specialized cell behavior").

These proteins instruct cell behavior in the surrounding neuroectoderm.

Medical devices with built-in biological computers could monitor, or even alter, cell behavior from inside a patient's body.

Thus, changes in levels of specific proteins in cells is one way that androgen receptors control cell behavior.

With more generations, this form of reproduction began to include specialized cell behavior.

Cell signaling - Regulation of cell behavior by signals from outside.

This variability in turn can have tremendous consequences on cell behaviour, and must be mitigated or integrated.

Noise in gene expression can have tremendous consequences on cell behaviour, and must be mitigated or integrated.
