A large-scale study of African elephant genetics in Tanzania reveals the history of elephant populations, how they interact, and what areas may be critical to conserve in order to preserve genetic diversity for species conservation. Mastodons had long black-auburn hair on their body and possibly an underfur (shorter dense fur underneath the primary hair) to help keep warm in colder climates.
