Although it's filled with stunning scenes re-creating the realities of life in prehistoric times, this A&E docudrama shouldn't be confused with 10,000 BC, the big-screen epic about prehistoric life directed by Roland Emmerich. In this program, you'll follow the earliest humans as they interact with a variety of now-extinct creatures, including woolly mammoths and saber-toothed tigers, as well as a few animals that are still around today.
