Homo sapiens (us) lived through the Stone Age along with genetic cousins such as Homo erectus and Homo habilis.Our ancestors achieved a number of major developments during the Stone Age, key innovations that not only assured our survival in a harsh world, but laid the foundation for the more dramatic innovations that have shaped our world today. Common types of these air-powered hand tools that are used in industry include buffers, nailing and stapling guns, grinders, drills, jack hammers, chipping hammers, riveting guns, sanders and wrenches.
Set up screens or shields in areas where nearby workers may be exposed to flying fragments, chips, dust, and excessive noise. SewingFlax fibers more than 34,000 years old have been discovered that had been spun to make thread.
Our ancestors fashioned needles from animal bones and used the thread to sew animal hide and fur into clothes, shoes and packs and to create string or yarn that had many uses including hefting and being used in making baskets and other domestic pieces.But what was particularly interesting about these fibers, found in the Republic of Georgia, was their color.


So much for Stone Age people walking around in dull variations of beige, here is evidence that they made an effort to introduce color into their lives.Perhaps even a sense of fashion? Indeed Neanderthals and Homo sapien were known to have existed in the same areas of ancient Europe together up until the Neanderthals disappeared around 35,000 years ago.Music. Long Hunting SpearFor the purposes of getting food and defending themselves Stone Age man had to contend with numerous creatures that had sharp claws and teeth.
Stone AxeOur Stone Age ancestors made a giant leap when they invented the stone axe somewhere between 250,000 and 1.2 million years ago. ShelterAmazingly, the earliest evidence that our ancestors built fixed shelters is from around 2,000,000 years ago. These shelters showed evidence of a hearth or fireplace and separate rooms representing a major improvement in living conditions for people using the shelter.


The Controlled Use of FireFire wasn’t discovered as such as it existed before Homo Erectus harnessed its power, however the ability to control fire was the greatest step forward in the history of mankind and our ancestors.Fire enabled us to cook food meaning we were better nourished, keep warm which meant we were better rested, migrate into colder climates which saw us diversify across the globe, fight away predators, clear forests for agriculture and bake clay to make utensils.
Evidence clearly places the earliest wheels in the Middle East and Central Europe between 3,400 BC and 3,000 BC. Our Stone Age friends did not have the wheel.Interestingly, homo sapien (mankind) faced extinction as recently as 75,000 years ago when the total population of homo sapien on earth was as low as 600 individuals. Perversely, this low base allowed strong genes to come through and according to some archaeologists, mankind took a ‘great leap forward’ at this time, resulting in our rapid rise to dominance.
