Median-joining network of L1 subfamilies. The network was reconstructed using Hs and Pt L1 elements. Empty circles represent Hs L1 subfamilies. Filled circles represent Pt L1 subfamilies. Lineage names and ages of some nodes are shown. The lines represent substitution steps, with a one-step distance indicated in the bottom-right corner. The network is also classified as yellow (L1PA3 and L1PA2-1A), pink (L1PA2), green (L1Hs) and blue (L1Pt) shadow boxes.
