text: The origin of the inner integument therefore dates from before the separation of the living angiosperm and gymnosperm lineages, believed to have occurred over 300 million years ago (MYA), while the outer integument must have arisen somewhere along the angiosperm stem lineage, perhaps as recently as ∼164 MYA: a reasonable estimated date for the most recent common ancestor (MRCA) of living angiosperms (Moore et al., 2010).
