Repeated DNA sequences in primates having identical or nearly identical members and exhibiting unusual phylogenetic specificity were analyzed. They appeared in repeated DNA sequences in each group of primates, probably within the last 10 to 15 million years, and are conserved to the same extent as unique DNA sequences. The finding allows a new approach to the construction of evolutionary trees.
