Throughout this discussion, which I've been following with interest, I've
had a feeling that people are confusing 'clade' with 'clan' and using them
interchangeably. Have a look at Vincent's definition of 'clade' below, then
compare it with Wikipedia's definition of 'clan' at
http://en.wikipedia.org/wiki/Clan - seems remarkably similar.
