Comparison of a phylogeny obtained by sequence data with the distribution of cladistic markers. The neighbor-joining tree is based on the sequence of the 5‘end of intron 1 in addition to the sequence from the region surrounding the Alu elements. Major primate groupings (Catarrhini, Platyrrhini, Haplorrhini, and Strepsirrhini) correspond to clades indicated on the tree. The numbers at nodes indicate the percentage of recovery of that node in 500 bootstrap replications. The presence and absence of Aluelements and of an 870 bp-deletion at the 3‘end of intron 1 are indicated by + and − symbols, respectively. The names of unique Alu elements are given where they occur.
