Instead of looking at organisms that are related, these scientists instead focus on situations where a derived trait surfaces in two lineages that lack a recent common ancestor.
The earliest trogon fossil with a heterodactyl foot (a derived trait uniting all extant trogoniformes) is Primotrogon wintersteini, described from one French specimen dating to the Oligocene (33 mya).
The function of annelid host use by Ur. sapphirina is not yet established, and the molecular analyses and field observations we report cannot discount the possibility that annelid host use by Ur. sapphirina could be a derived trait that evolved to serve a non-reproductive function, such as preventing dehydration or supplementing energetic reserves.
