Claim: Prodoxidae, a family of moths belonging to the insecta class, have an evolutionary relationship to Yucca plants, which are notable for their rosettes of tough leaves.
Evidence: The Prodoxidae are a family of moths, generally small in size and nondescript in appearance. Insecta Class: Researchers have again tried to demonstrate the absolute minimal level of evolution needed to secure a yucca plant and moth mutualism. The researchers attempt to find an answer as to how integral coevolution was as the driving force behind various adaptions between the yucca moth and plant species. Certain mutualistic traits have predated the yucca moth-plant mutualism, such as larval feeding in the floral ovary; however, it suggests that other key traits linked to pollination were indeed a result of coevolution between the two species. Its 40–50 species are notable for their rosettes of evergreen, tough, sword-shaped leaves and large terminal panicles of white or whitish flowers.
