Evolution and adaptation in Rhagovelia bedbugs
Genes at the origin of new traits giving access to a new environment chez la punaise Rhagovelia (Heteroptera, Gerromorpha, Veliidae) Evolutionary innovations result in the appearance of new structures or behaviours during evolution (ex lien), a coloration pattern in butterflies (lien). The theory predicts that these events of appearance are unique to each innovation and…
