Caterpillars did not evolve from onychophorans by hybridogenesis.
The evolution and loss of distinctive larval forms in animal life cycles have produced complex patterns of similarity and difference among life-history stages and major animal lineages. One example of this similarity is the morphological forms of Onychophora (velvet worms) and the caterpillar-like larvae of some insects. Williamson [(2009) Proc Natl Acad Sci USA 106:15786-15790] has made the as...
متن کاملCaterpillars evolved from onychophorans by hybridogenesis.
I reject the Darwinian assumption that larvae and their adults evolved from a single common ancestor. Rather I posit that, in animals that metamorphose, the basic types of larvae originated as adults of different lineages, i.e., larvae were transferred when, through hybridization, their genomes were acquired by distantly related animals. "Caterpillars," the name for eruciforms with thoracic and...
متن کاملHow Did T3S Evolve?
The injectisome has a common evolutionary origin with the bacterial flagellum, as suggested by the fact that the basal bodies of both nanomachines are similar and include many proteins with a significant similarity. Moreover, there are also functional similarities, such as the use of specific chaperones (5, 45, 104, 108, 138) or of molecular systems regulating the size of the external appendage...
