But bilateral symmetry does not imply much complexity - it only sets the stage for a polarized body plan with a head end and a tail end. These were very primitive microscopic organisms.
Certainly.
However what it does show is that the basics for life as we see it today go back at least to the precambrian, and that the precambrian is NOT some sudden appears of forms never before seen, but rather the basics for the lifeforms found in the cambrian explosion can be seen more than 40 million years earlier.
Neither of these facts seem to provide much of a YEC explanation though and so far I have noticed that as usual, the YEC model to explan what is seen has been noticably missing from this thread.
Why is it that so far NO YEC has ever been able to present a model that adequately explains anything seen?
