In interpreting a cladogram,
A) we can identify the specific ancestor of each taxon by tracing each branch back to the node closest to the root
B) taxa on the right side of a cladogram have evolved from the taxa on the left side
C) the relative placement of smaller branches allows us to determine the number of years since a particular taxon has evolved
D) we can determine relationships by tracing along the branches back to the most recent common ancestor
E) we must first identify horizontal gene transfer
