I've been having such a hard time figuring out phylogeny and I've been doing a lot of research but I just can't find the answer. Does anyone know/understand this and can they explain it to me? what group did fungi break off us and what were the mafor developments/features make it a new taxon? Also, what groups broke off of fungi and why. This all has to do with the theory that all organisms evolved from a single organism.
