The use of genome-level characters for phylogenetic reconstruction.
Now that large-scale genome-sequencing projects are sampling many organismal lineages, it is becoming possible to compare large data sets of not only DNA and protein sequences, but also genome-level features, such as gene arrangements and the positions of mobile genetic elements. Although it is unlikely that comparisons of such features will address a large number of evolutionary branch points across the broad tree of life owing to the infeasibility of such sampling, they have great potential for resolving many crucial, contested relationships for which no other data seem promising. Here, I discuss the advancements, advantages, methods, and problems of the use of genome-level characters for reconstructing evolutionary relationships.
