Body proportions of these creatures were similar to those people who live in warm climates and may reflect african origins of these people. 3 billion bases in human genome, 1. 06% differences represents differences in about 30 million nucleotides: approx. Able to occupy a difficult, cold, dry habitat and extended range further north and east than previous hominins did: technology. Assembled more sophisticated and more highly standardized tools made from wider variety of materials, including antler, ivory, bone.
