<p>Gel photographs displaying the methodology for establishing evolutionary relationships using <i>Alu</i> elements. The presence and absence of elements, supplemented by sequencing to eliminate the possibility of confounding events, is used to determine which species are more closely related. A total of 5 gel electrophoresis results on a 24-species primate panel are shown with <i>H. sapiens</i> and <i>G. senegalensis</i> as outgroups. <b>A:</b> Amplification of locus Str71B, an <i>Alu</i> insertion shared by the infraorder Lemuriformes. <b>B:</b> Amplification of locus MmA39, an <i>Alu</i> insertion shared by the family Cheirogaleidae. <b>C:</b> Amplification of locus MmA27, an <i>Alu</i> insertion shared by the sister genera <i>Microcebus</i> and <i>Mirza</i>. <b>D:</b> Amplification of locus Str59, an <i>Alu</i> insertion specific to the genus <i>Microcebus</i>. <b>E:</b> Amplification of locus Em6, an <i>Alu</i> insertion affirming the monophyly of the family Lemuridae to the exclusion of other lemur species and outgroups.</p
