Prehistoric America

Half the world's population speaks a language that has evolved from a single prehistoric mother tongue. First spoken in Stone Age times on the steppes of central Eurasia 6,500 years ago, this mother tongue spread from the shores of the Black Sea across almost all of Europe and much of Asia. It is the genetic basis of everything we speak and write today - the DNA of language.

Take a journey into our ancient past. Explore a long-lost landscape and gradually discover the minds, beliefs and cultural practices of those souls who lived on these lands thousands of years before you. Travelling the length and breadth of Britain, James Canton pursues his obsession with the physical traces of the ancient world: stone circles, flint arrowheads, sacred stones, gold, and a lost Roman road.

Most scientists believe the evolution of humans has a history nearly as long as life itself. Anatomically modern humans and all other life that has existed on the planet first came about from the single-celled microorganisms that emerged approximately four billion years ago. Through the processes of mutation and natural selection, all forms of life developed, and this continuous lineage of life makes it difficult to say precisely when one species completely separates from another.
