It seems as though every series is coming to an end for the summer of late, and Ice Age Giants is no exception. In the final installment of this fascinating series, Alice Roberts sets out to discover what happened to two more wonderful creatures who walked the earth almost 40,000 years ago. She'll be telling us how the wooly rhino's survival was hampered by increased snowfall, and revealing how internal discord among the mastodons lead to their demise. Here's hoping there's more where this breed of wonderful telly came from in future.
