don't think anyone could say that M. jannaschii is close to the (last) common
ancestor. It is exactly (in real time) the same 'distance' from the last common
ancestor as you or I. The genome sequence may (or may not) have evolved at
a faster rate. In any case, M. jannaschii is very different from what the LCA could
have been like.
Sorry if I sound overly didactic, but when people talk about the archaea as 'ancient'
or 'primitive' it bothers me.
