Phylogenetic trees are typically created from DNA, RNA or protein sequence data. Apart from ... WebA clade, either to be bound or to be the reference, must be indicated by collating the names of the two phylogenetically furthest tips belonging to it, separated by a “-”. The ‘bound’ tips/clades can be used as reference for another tip/clade to be attached. The order with which clades and tips to attach are supplied does not matter.
