6-Stone Age

Stone Age (3.3 million to 1.5 million years ago): This is the age of the rise of simple symbolic thought and the dexterous human hand (nature) and the beginning of crafting tools (nurture).

Earliest Known Toothpicks

Homo habilis, one of the earliest known human ancestors, emerged around 2.3 million years ago with a brain size significantly larger than modern chimpanzees. By around 1.8 million years ago, they became the first species known to use toothpicks for dental hygiene, alongside their advanced tool use for specific tasks like skinning animals and cutting […]

Human Thumb Evolves

Slightly greater range of movement and precision: Around 2 to 3 million years ago, the evolution of the human thumb reached a pivotal point. Early hominins, such as Australopithecus and later Homo habilis, exhibited a thumb that was more similar to that of modern humans. This thumb was capable of a greater range of movement

Olduvai Gorge Site: A Glimpse into Early Organizational Behavior

The Olduvai Gorge in Tanzania stands as a testament to early human ingenuity and foresight, illustrating a rudimentary form of organizational behavior that predates modern civilization. Utilized extensively over two million years, the site functioned akin to a “factory,” where early humans systematically crafted a variety of stone tools. They strategically selected specific locations that

Early Wood tools

Simple wood tools starting with picking up a stick to poke at some out of reach fruit likely paralleled the use of stone tools. Wood tools for the most part did not survive the test of time. The earliest so far include advanced javelins form 400,000 years ago and a digging tool from 780,000 years ago.

First Proto-Containers

The earliest containers were likely simple natural resources that early hominins stumbled upon and adapted for use. Starting possibly with Homo habilis around 2.0 million years ago, these early humans may have utilized large leaves, shells, or naturally hollowed-out pieces of wood as rudimentary containers. This usage marks an innovative step in early human technology,

Genus: Australopithecus

116,000 Generations Ago This genus is more directly ancestral to humans and includes several species, such as Australopithecus afarensis (famously represented by “Lucy”), Australopithecus africanus, and others. Australopithecines show a greater commitment to bipedalism and have features more closely resembling modern humans, although they still retained some adaptations for climbing. This genus is known for

Hand Axe

70,400 Generations Ago (from 2020 CE) By about 1.76 million BCE, early humans began to create hand axes. They would strike really large flakes, then continue to shape them around the edges. On the right, the hand axe pictured dates to circa 1.1 million BCE. It was found at Isampur, India.

Early Stone Tools

The earliest known stone tools date back to at least 3.3 million years ago. They are identified by their purposeful flaking patterns, sharp edges, and location with other more identifiable artifacts or fossils. They are then verified with microscopic analysis confirming repetitive use.
