Mammoths and other large animals survived in the north much longer than previously believed. New DNA research indicates that the climate, not humans, led to the demise of these large creatures, Norway Science, January, 2022 The open access paper is: Wang, Y., Pedersen, M.W., Alsos, I.G., De Sanctis, B., Racimo, F., Prohaska, A., Coissac, E., Owens, H.L., Merkel, M.K.F., Fernandez-Guerra, A. and Rouillard, A.,2021. Late Quaternary dynamics of Arctic biota from ancient environmental genomics. Nature, 600(7887), pp.86-92. It concludes that mammoths survived in continental northeast Siberia until 7,300 BP; North America until 8,600 BP; and the Taimyr Peninsula as late as 3,900 BP. Yours, Paul H.
