Archaeologists recently uncovered a pygmy mammoth skull on Santa Rosa Island in Channel Islands National Park that could answer questions about how the species evolved.The skull, discovered by a park intern, is surprisingly intact and will hopefully reveal more about the evolution of the Columbian mammoth into the pygmy mammoth species in response to a changing environment. Nick Hinojosa and his classmates at Etiwanda High School report on how age-old discoveries continue to teach us about natural history and provide guidance for the future.
