Well taken. The imnportant qualifier to Elsasser's treatment is "in the same
sense as the laws of physics." That is, they depend on the continuum
nature of time-space. That doesn't seem to apply to the laws that you
suggest.

I think it pertains to the increase of "overhead" (dissipative overhead,
to be precise.)
Of course, I could have included my principle of increasing ascendency as
a putative law, but I don't see it as a law per-se. I see it as derivative
of a process -- the autocatalytic process to be precise.
I suspect the same might apply to the "laws" you cite. It's just that I'm
not a good enough biologist to put my finger on the underlying processes.
The best,
Bob
