Anthropologists theorize that over generations, the surface area of the Chukchism body was reduced in order to adapt to their extreme living conditions. They developed smaller, rounder trunks and shorter fingers, arms and legs, thus turning their bodies into small furnaces designed to preserve body heat.

JOURNEY OF MAN tells the remarkable story of the human journey out of Africa and into the rest of the world, tracing history through evidence uncovered in the Y-chromosome of mans DNA. Traversing six continents, the film takes viewers on a fascinating journey into the hidden world of their ancestry and offers a modern look at our ancestors lives.
