Asplit inphylogenetics is a bipartition of a set oftaxa, and the smallest unit of information in unrootedphylogenetic trees: each edge of an unrooted phylogenetic tree represents one split, and the tree can be efficiently reconstructed from its set of splits. Moreover, when given several trees, the splits occurring in more than half of these trees give rise to a consensus tree, and the splits occurring in a smaller fraction of the trees generally give rise to a consensussplit network. Pairs of splits arecompatible if any of the subsets defined by each split do not overlap.[2]
