What is the sense in which wood bison are considered the closest living relatives to the extinct steppe bison (*Bison priscus*)?
Answer
Evolutionary tie to the region, as they were reintroduced to Siberia.
The wood bison holds a specific evolutionary significance related to ancient megafauna, linking them to Asian history. They are identified as the closest living relatives to the extinct steppe bison, *Bison priscus*, which once ranged widely across Siberia. This evolutionary connection underpinned an extraordinary international conservation effort. Starting in 2006, disease-free wood bison were shipped from Elk Island National Park (EINP) in Canada to the Sakha Republic (Yakutia) in Russia to initiate a 'rewilding' project in climatically comparable conditions, demonstrating their adaptability and reinforcing their historical lineage connection to that region.
