Why wouldn't one make the comparison with the human genome? If the evolutionay mechanisms credited with responsibility for the jump from nucleobases to archeobacteria (which is still incredible, if true) can't be fully and comfortably accredited with the nucleobase to human genome jump then said evolutionary mechanisms are suspect. According to the notion of evolution inherently adding complexity over time, nucleobases to human genome just requires some very large time. If we do know this with such certainty, then my comparison is both apt and reasonable.
