Eukaryote origins, cicadas, and silkworm sex

Gene similarity networks provide tools for understanding eukaryote origins and evolution
"multiple signatures of the chimerical origin of Eukaryotes as a fusion of an archaebacterium and a eubacterium that could not have been observed using phylogenetic trees... archaebacterial repertoire has a similar size in all eukaryotic genomes whereas the number of eubacterium-derived genes is much more variable"

Independent divergence of 13- and 17-y life cycles among three periodical cicada lineages "at any given location, up to three distinct species groups (Decim, Cassini, Decula) with synchronized life cycles are involved... life-cycle synchronization of invading congeners to a dominant resident population enabled escape from predation" [OK, but why not 7 and 11 years?]

Transgene-based, female-specific lethality system for genetic sexing of the silkworm, Bombyx mori

Neo-sex chromosomes and adaptive potential in tortricid pests "fusion between an ancestral Z [sex] chromosome and an autosome corresponding to chromosome 15 in the Bombyx mori reference genome... conferring insecticide resistance and clusters of genes involved in detoxification of plant secondary metabolites under sex-linked inheritance"
