Figure 3

Median-joining network of the L1 elements associated with L1IMD. Empty circles denote human-specific L1 elements. Filled circles denote chimpanzee-specific L1 elements. The size of circles indicates the number of L1 loci with that sequence type. The lines denote substitution steps, with a one-step distance indicated in the top-left corner. The subfamily-specific diagnostic sequence positions (corresponding to positions 5930–5932 and 6015 in the 3′-UTR of the full-length L1 consensus sequence) are specified below each relevant node.
