It is rather easy to track male lineage via the Y chrosome. Mutations do not interfere with tracing of lineage.
Either you refuse or AFFECT to refuse to notice (typical evo bad faith) that the same sort of tracing could be used more conventionally and reliably (there's never the issue of wondering about fidelity, for instance) with the XX. You'd still have the matter of Noah's wife and the common ancestry for discussion to demonstrate the same point as with the more unreliable Y. But an FRevo is never able to discuss anything.
As for millions of lurkers, I hardly think the evo threads are very popular. But they're popular enough for people to be regularly warned about How Evos Behave.
Perhaps this our opportunity to clarify the whole 'information' problem, from a bona fide mathematician.
How about it Mamzelle? Care to tell us what measure of information is to be used for biological organisms and why?
Could you also explain to us why such things as point mutations, gene duplication followed by a point mutation, and polyploidy do not result in an increase in information?
Heck, while you are at it, mind explaining why any 'information increase' is necessary for evolution to take place? Why can not a single 'change' in a gene, say a HOX gene, produce a different morphology?
