However, long-time friends help us see more clearly. A study published in 2011 in the journal Molecular Biology and Evolution Saw two species of contemporary lice: D Pediculus capitis head lice, Used for our skulls, and Human body lice, Is the host of our clothing. By increasing the speed of their DNA mutations, researchers estimated that the parasites differentiated between 170,000 and 83,000 years ago, evidence that nudity was no longer a distant memory.

Overview of tools teaches us a little more. Scars left on animal bones suggest that Neanderthals had already recovered skins and ax from their prey. The first eye needles made of bone or ivory date back to around 20,000 years. Equipped with the animal tendon in the form of a thread, the sapiens were able to assemble a larger property in this ice age as more fit and therefore more protective parts. Ian Gilligan of the University of Sydney believes that this sewing talent could be a decisive advantage in Sapience’s expansion. But our ancestors were not only cautious… they were beautiful too!
