Charles, the asterisks are to denote that the name is part of a bionem -
they are used to represent the italicisation of the name in ASCII text.
David Marjanovic and Jaime Headden use them, I think.  Others (including
myself) tend to use the underscore character instead of the asterisk,
because the asterisk is sometimes used as a mutiplication character, and the
underscore doesn't appear to be used for anything else.  Also, the
underscore is less visually intrusive upon the conained text.  Thus I would
right my favourite species of plesiosaur as _Kronosaurus queenslandicus_,
whilst David would right *Turdus merula* for one of his favourite backyard
birds.  Currently, each version is equally acceptable, at least on this

As for the other stuff, you'll have to ask a cladist :-)
