摘要

Rare events have played an increasing role in molecular 系統發育s as potentially homoplasy-poor characters. In this contribution we analyze the 系統發育 資訊 content from a combinatorial point of view by considering the binary relation on the set of taxa defined by the existence of a single event separating two taxa. We show that the graph-representation of this relation must be a tree. Moreover, we characterize completely the relationship between the tree of such relations and the underlying 系統發育 tree. With directed operations such as tandem-duplication-random-loss events in mind we demonstrate how non-symmetric 資訊 constrains the position of the root in the partially reconstructed phylogeny.
