Horizontal gene transfer in evolution: facts and challenges

Abstract
The contribution of horizontal gene transfer to evolution has been
controversial since it was suggested to be a force driving evolution in the
microbial world. In this paper, I review the current standpoint on
horizontal gene transfer in evolutionary thinking and discuss how important
horizontal gene transfer is in evolution in the broad sense, and
particularly in prokaryotic evolution. I review recent literature, asking,
first, which processes are involved in the evolutionary success of
transferred genes and, secondly, about the extent of horizontal gene
transfer towards different evolutionary times. Moreover, I discuss the
feasibility of reconstructing ancient phylogenetic relationships in the face
of horizontal gene transfer. Finally, I discuss how horizontal gene transfer
fits in the current neo-Darwinian evolutionary paradigm and conclude there
is a need for a new evolutionary paradigm that includes horizontal gene
transfer as well as other mechanisms in the explanation of evolution.
