Four lifelike reconstructions of prehistoric humans have been unveiled — including a model of a species often dubbed "the hobbit," which, as an adult, was about the same height as a modern 4-year-old.
The 3D models are featured in the upcoming five-part documentary series "Human," which explores the extraordinary story of human evolution over the past 300,000 years, from our rise in Africa, to our migration into Eurasia and across the globe, including to our journey through the Americas after going along the Bering Land Bridge during the last ice age.
