TinT activity patterns and species evolution. Schematic representation of the phylogenetic relationships of the five major primate groups: Strepsirrhini (represented by Microcebus murinus), Tarsiiformes (represented by Tarsius syrichta), Platyrrhini (represented by Callithrix jacchus), Cercopithecoidea (represented by Macaca mulatta), and Hominoidea (represented by Homo sapiens). The dating is taken from [25, 26]. AluJo elements were active at the divergence of Strepsirrhines and AluJb at the divergence of Tarsiiformes. The main activity of AluS elements occurred around the evolution of Anthropoidea; AluY elements arose on the lineage leading to Cercopithecoidea and are still active in Catarrhini, including Macaca mulatta and Homo sapiens. Group-specific Alu elements are indicated at terminal branches (L = AluL, La = AluLa, Mim = AluMim; Ta = AluTa; YR = AluYR).
