Comments P.11263 right column bottom paragraph: "If current lineages simply persisted without any new speciation or extinction, it would take nearly 500,000 y for the ∼5,400 current mammal species to evolve enough new history to restore net PD to preanthropogenic levels." P.11265 left column 2nd paragraph: "Even if background extinction rates effectively slowed to a stop (μ = 0), speciation rates in mammals would still have to be about twice as high as their highest levels during the Cenozoic to restore PD debt within 500,000 y."
