How is a mass extinction event indicated in the Tree of Life? Significant gaps on the tree are created when many branchings across the tree come to a common halt and do not continue past a point in time. There is only one mass extinction event and it is ahead of us, the Anthropocene. All branches suffer in an extinction event and none persist subsequently. All existing branches of a tree terminate at this point, with none surviving a mass extinction event. A few branches across the tree terminate at a similar time. O O O
