Ludvig has repeatedly posted claims that phylogeny programs assume a
molecular clock.  He has repeatedly been told, by lots of people, that
they don't and asked to provide documentation that they do.  Now he's back
again saying the same thing.

Once again, he needs to be asked to provide evidence for his claims.  He
never has provided it in the (many) past rounds of this argument. There
is no reason to waste bandwidth on his postings until he provides it.
