RECALIBRATED TREE OF LEAF BEETLES (CHRYSOMELIDAE) INDICATES INDEPENDENT DIVERSIFICATION OF ANGIOSPERMS AND THEIR INSECT HERBIVORES.

Recalibrated tree of leaf beetles (Chrysomelidae) indicates independent diversification of angiosperms and their insect herbivores.

The great diversity of the "Phytophaga" (weevils, longhorn beetles and leaf beetles) has been attributed to their co-radiation with the angiosperms based on matching age estimates for both groups, but phylogenetic information and molecular clock calibrations remain insufficient for this conclusion.A phylogenetic analysis HERBATINT 6N of the leaf be

IntroductionSkin aging is an inevitable physiological process driven by factors like cellular senescence, ultraviolet radiation (UV) radiation, and environmental pollutants.A key feature is the accelerated collagen degradation in the dermal extracellular matrix, leading to visible signs such as sagging, wrinkles, and hyperpigmentation.Traditional f
