Angiosperms are thought to be monophyletic (all descendants derived from a common ancestor) and there are an abundance of fossils from the mid-cretaceous period, however, abundance does not mean origin, so the exact time of angiosperm origin is still widely debated. It is thought that insects played a major role in angiosperm development so the evolution of both need to be explored to fully understand angiosperm origin (according to some). Even geographic origin is widely debated between high-latitudes, and a more tropical location and migrated from there.
