To have, what we recognize as life, requires the complexity we see, with multiple gene functions, for each gene, as mediated by miRNA's. That way 20K genes do the work of 100K. What simplistic genetic structures preceded life as we now know it, is one problem. We know nothing of it. But we do know what structures are necessary for exact reproduction for true life once it appeared, and from what we are learning, that hasn't changed much, and gets more and more complicated as research rolls on.
