In this paper, we describe a new technique for amalgamating rooted phylogenetic trees. This appears to be the first such method to provably exhibit particular desirable properties which we list and establish.enCopyright Charles SempleFields of Research::49 - Mathematical sciences::4904 - Pure mathematics::490401 - Algebra and number theory
