Summary Introduction

To explain: The multiple lateral gene transfers between the same two branches on a phylogeny expected to be rare, at least compared with the similarities inherited through the stable core.

Introduction: Lateral gene transfers are the transfer of genetic material from an organism to another. This transfer is in contrast with the vertical transfer that occurs from ancestor to the progeny or daughter generations. Lateral gene transfer causes distortions in the depiction of evolutionary relationships.
