As one of the most successful organisms in tropical and subtropical ecosystems, termites are well-known for their essential roles in organic matter decomposition, soil structure engineering. and also as pests that consume timber despite only a small group feeds on wood. Phylogenetic relationships among families and subfamilies of this group are robust for some lineages, but topologies within basal lineages and at the genera level are still ambiguous for many lineages. Recent researches date the split between termites and wood-feeding cockroaches back to 170 Ma with the most recent common ancestor arose at 149 Ma. This indicates the current termite distribution pattern may have been influenced by the breakup of Pangaea and Gondwana, however the precise origin of termites was failed to be estimated due to the limited sample size of early lineages. In my thesis project, I will sequence the whole mitochondrial genomes of termites which are selected to be on behalf of the taxonomic and geographical diversity of some uncertain clades. With this database, I will be able to determine the precise origin and distribution patterns of unresolved termite lineages, and the most reliable evolutionary story of termites in continent level.
