Despite more than half a century of research, the evolutionary origin of termites remains unresolved [1] [2] [3]. A clear picture of termite ancestry is crucial for understanding how these insects evolved eusociality, particularly because they lack the haplodiploid genetic system associated with eusocial evolution in bees, ants, wasps and thrips [4] [5]. Termites, together with cockroaches and praying mantids, constitute the order Dictyoptera, which has been the focus of numerous conflicting… Expand
Evolution of Termite Symbiosis Informed by Transcriptome-Based Phylogenies
TLDR
This key finding indicates that comb building is a derived trait within Termitidae and that the creation of a comb-like "external rumen" involving bacteria or fungi may not have driven the loss of protozoa from ancestral termitids, as previously hypothesized. Expand
A global molecular phylogeny and timescale of evolution for Cryptocercus woodroaches.
TLDR
This study generated mitochondrial, nuclear, and Blattbacterium endosymbiont sequence data for 8 new Chinese species, and combined these with previously available data to undertake the most extensive analysis of phylogenetic relationships within the genus to date, suggesting Cryptocercus was originally distributed across both continents. Expand
Phylogenetic evidence for a single, ancestral origin of a ‘true’ worker caste in termites
TLDR
A test for correlated evolution which takes phylogenetic structure into account indicates that this pattern is of biological significance and suggests that the variable occurrence of a worker caste in termites has ecological determinants, apparently linked to differences in feeding and nesting habits. Expand
A mitochondrial genome phylogeny of termites (Blattodea: Termitoidae): robust support for interfamilial relationships and molecular synapomorphies define major clades.
TLDR
A highly supported tree of termite relationships was produced, however the relationship of the termites+Cryptocercus clade to other cockroach lineages was highly affected by the strong nucleotide compositional bias found in termites relative to other dictyopterans. Expand
Phylogeny of Dictyoptera: Dating the Origin of Cockroaches, Praying Mantises and Termites with Molecular Data and Controlled Fossil Evidence
TLDR
The authors' datings suggest that crown-Dictyoptera—and stem-mantises—would date back to the Late Carboniferous, a result compatible with the oldest putative fossil of stem-dictyopteran suborders, and suggests a scenario of replacement in carnivory among polyneopterous insects. Expand
Termites (Isoptera): Their Phylogeny, Classification, and Rise to Ecological Dominance
TLDR
The first phylogeny of termite lineages using exemplar Cretaceous, Tertiary, and Recent taxa was presented, revealing extensive grades of stem-group taxa and the divergence of some modern families in theCretaceous. Expand
Termite evolution: mutualistic associations, key innovations, and the rise of Termitidae.
TLDR
An overview of the key innovative traits acquired by termites during their evolution, which ultimately set the stage for the emergence of "higher" termites, and discusses two hypotheses concerning the loss of protists in Termitidae. Expand
The evolutionary history of termites as inferred from 66 mitochondrial genomes.
TLDR
The inference of ancestral geographic ranges shows that the Termitidae, which includes more than 75% of extant termite species, most likely originated in Africa or Asia, and acquired their pantropical distribution after a series of dispersal and subsequent diversification events. Expand
Termite Phylogenetics and Co-cladogenesis with Symbionts
TLDR
A consensus has emerged that the sister-group of termites is the wood-feeding cockroach genus Cryptocercus, and that the digestion of wood by the common ancestor of these two groups was aided by cellulolytic hindgut flagellates. Expand
The phylogeny of termites (Dictyoptera: Isoptera) based on mitochondrial and nuclear markers: Implications for the evolution of the worker and pseudergate castes, and foraging behaviors.
TLDR
The data support a traditional hypothesis of foraging behavior, in which the evolutionary transition from a one-piece type to a separate life type occurred through an intermediate behavioral form. Expand

TLDR
It is indicated that cockroaches are a monophyletic group, whose sister group is Mantoidea, and the phylogeny inferred here does not support a close relationship between C. punctulatus and M. darwiniensis. Expand
Characterizing the Ancestors: Paedomorphosis and Termite Evolution
TLDR
It is suggested that the tempo and mode of their evolution confound efforts to determine the phylogenetic relationships among termites, mantids, and cockroaches, and that recognition of the connection between ontogeny and phylogeny in the Dictyoptera is essential to resolving some of the long standing issues regarding the phylogenetics origin and subsequent evolution of the included taxa.

Phylogenetic relationship among cockroach families inferred from mitochondrial12S rRNA gene sequence
TLDR
A phylogenetic analysis of relationships among representative genera of the five cockroach families was undertaken, suggesting that Polyphagidae may belong to the superfamily Blattoidea rather than to Blaberoidea as proposed by McKittrick (1964). Expand
Phylogeny of Insect Orders
TLDR
This review is devoted to a treatment of the phylogeny of extant orders of insects and their closest relatives and to the numerous new proposals made in a thought-provoking, recent book by Boudreaux (15). Expand

TLDR
Living species of the cockroach family Cryptocercidae have intestinal symbionts that are congeneric with some of the gut protozoa found in Isoptera, and by occasionally killing and consuming an intruder from the other group, gutprotozoa could have been acquired and exchanged between termites and cryptocercus or their ancestors.

DNA sequences from a fossil termite in Oligo-Miocene amber and their phylogenetic implications.
TLDR
Phylogenetic analysis of fossil and extant 18S rDNA confirmed morphological cladistic analyses of living dictyopterans (termites, cockroaches, and mantids) and affects molecular phylogenetic hypotheses of termites in this, the oldest DNA yet characterized. Expand
High relatedness and inbreeding at the origin of eusociality in gall-inducing thrips.
TLDR
Results indicate that unusually high relatedness is associated with the origin of eusociality, and they suggest a role for inbreeding in the evolution of bisexual helping. Expand

Endogenous endo-beta-1,4-glucanase, when expressed in Escherichia coli, was shown to have in vitro activity against carboxymethylcellulose and NtEG, a gene putatively encoding an EGase from Nasutitermes takasagoensis (Termitidae), was determined. Expand
