Problem: Was the mammoth steppe vegetation community nearly identical to the Africa savannah? How big was the mammoth steppe and how far did the steppe expand across Europe and Eurissa and into North America? Where the megafauna like Mammoths, horse,musk ox, steppe bison, Woolly Rhino, Cave lions, pay a mirror ecology image that found in Africa like Elephants, Zebra, Africa buffalo, Rhino, Wildebeest, African lion? What would if Dr Church de extinction megafauna from the mammoth steppe and release them back into Wild?
