- Differences in bases are indicated in the table for each sample, a full stop denotes identical bases and an asterisk denotes a deletion. Missing sequence data from the ancient samples are denoted by question marks. Haplotype within clade D1 have an 11 bp insertion at position 16089i, which is a repeat of the sequence seen between 16,079 and 16,089 (TTTTAACTCTC). Sequence codes are given in the first column. In the final column, each sample has been assigned to a mitochondrial clade by means of its relative position in the larger network, and the variant sites compared with modern samples
