TL;DR: It is shown that Collembola, a wingless group traditionally considered as basal to all insects, appears instead to constitute a separate evolutionary lineage that branched much earlier than the separation of many crustaceans and insects and independently adapted to life on land.

TL;DR: Assessment of the current diversity and distribution of B. tabaci cryptic species in China shows that whereas in the past the exotic invader Middle East-Asia Minor 1 was predominant across China, another newer invader Mediterranean is now the dominant species in the Yangtze River Valley and eastern coastal areas, and Middle East, Asia Minor 1 is now predominant only in the south and south eastern Coastal areas.

TL;DR: Genetic similarity and assignment tests cluster the remaining populations into two genetic groups — Africa and a group including the Mediterranean basin and the American region, indicating that Africa, and not the Mediterranean, is the origin of flies infesting cultivated olive.

TL;DR: The complete 15,455-nt mitochondrial DNA sequence of the springtail Tetrodontophora bielanensis (Arthropoda, Hexapoda, Collembola), which shows the well-known A+T bias typical of insect mtDNA, and two tRNA translocations were found which were unprecedented among Arthropoda.

TL;DR: The finding of the reciprocal paraphyly of Hexapoda and Crustacea suggests an evolutionary scenario in which the acquisition of the hexapod condition may have occurred several times independently in lineages descending from different crustacean-like ancestors, possibly as a consequence of the process of terrestrialization.
