Let me try to be a little more specific. You say in your Occam paper at http://parallel.hpc.unsw.edu.au/rks/docs/occam/node4.html
"The first assumption to be made is that observers will find themselves embedded in a temporal dimension. A Turing machine requires time to separate the sequence of states it occupies as it performs a computation. Universal Turing machines are models of how humans compute things, so it is possible that all conscious observers are capable of universal computation. Yet for our present purposes, it is not necessary to assume observers are capable of universal computation, merely that observers are embedded in time. "
Are you meaning physical time, psychological time, or just a (linear) order? I am just
trying to have a better understanding.

Computational universality is not sufficient for open-ended evolution of life. In fact we don't what is sufficient, as evidenced by it being an open problem (see Bedau et al., Artificial Life 6, 363.)
I also suspect that it is not necessary for the evolution of SASes, but this is obvious a debatable point.
