How did the mixing of prehistoric human genes lead the way for survival of our human species?. Archaeology, genetics and anthropology cast new light to 200,000 years of human history detailing how early humans thrived from all around the globe.

When Homo sapiens arrived in Australia, they were, for the first time, truly alone, surrounded by wildly different flora and fauna. How did they survive and populate a continent? There is a close cultural and genetic link between the First Australians and modern-day Aborigines. The ancient and modern story intersect here as nowhere else in the world. The secret to this continuity is diversity. Intuitively, they found the right balance between being...

What happened when early humans ventured out of Africa and into Asia? Where did they go and whom did they meet along the way?

Because these ancient humans...
