Comparison of three independent methods for dating DNA transposons. Eleven distinct families of DNA transposons were shown to be primate specific by all three methods. Twenty-nine additional DNA element families were found to be primate specific by both the percent divergence and cross-species genomic analysis methods. Twenty-nine families predicted to be primate specific based solely on percent divergence and age were determined to be eutherian-wide by cross-species analysis.
