Phylogenies of L1 and B1 families. The phylogenies show species specificity of L1 and B1 families, and that S. hispidus-specific L1 families exist, but not B1 families. Panel a shows the L1 tree and b shows the B1 tree. To reflect divergence of the families, the trees were based on the distances between them. The distance between any two families was calculated by taking the average pairwise distance of the consensus sequences of subfamilies that belong to each family. Numbering of the L1 and B1 families is in chronological order of each element - similarly numbered L1 and B1 families do not necessarily correspond to the same time period
