Fig. 6

Evolutionary history of Perissodactyla L1. This composite diagram was constructed as a hand-drawn phylogenetic tree depicting the evolutionary history of Perissodactyla L1 families. Each family of L1 is represented by a schematic model of an L1 element and the blue lines that connect them show their evolutionary relationships. The numbered scale at the bottom of the diagram represents time in millions of years and the position of each L1 family reflects roughly their estimated age. Family copy numbers are shown in green text. The purple box represents the estimated split between the horse and rhinoceros between 52 and 58 Myr ago
