This model is represented in terms of a "damage index" which is a nonlinear function of maximum deformation and accumulated energy dissipation, and follows Weibull distribution.
The evidence from molecular clocks, fossils and geographic distribution data on the origin time of angiosperms has been greatly accumulated in the past two decades.
