WebYou can rotate branches as much as you like the tree is still the same, however if you break a branch and place it somewhere else then the resulting tree is no longer the same. Just for advice, a phylogenetic tree should not be read right to left, it should instead by read from the base up to the "leaves". Comment.

Depending on the scale of your study, the ingroup taxa might be very closely related to one another or not closely related at all.
