For at least 300,000 years, humans who looked like us have lived on Earth. Nothing in their appearance would distinguish them from people today. Their brains were as large as ours, but they were different—likely because they did not yet have language as we know it.
Sometime around 100,000 years ago, vocal communication developed into more structured language, with words and eventually sentences. As the brain and vocal abilities developed, communication became more complex. Language gave humans an evolutionary advantage by allowing more complex cooperation and symbolic thought.
Modern DNA evidence suggests that early humans were few in number—small enough to fit into a football stadium. Archaeologists have found fossils from present-day Ethiopia in the east to Morocco in the west, but so far, there is no evidence that a significant number of modern humans left Africa until about 70,000 years ago.
Language provided early humans a survival advantage. It allowed ideas to be shared and made more complex cooperation possible. These advantages enabled humans to expand into Europe and Asia, and by about 50,000 years ago, they had reached Australia.
Soon after, humans began creating objects and sounds that carried meaning beyond immediate survival. The earliest clear evidence of art appears in objects such as carved figurines, beads, and cave paintings, some dating back as far as 100,000 years. Some of the oldest known musical instruments, including simple bone flutes, date back roughly 40,000 years.
The population remained low because much of the land north of Africa was covered by ice or was too cold to support large numbers. Early humans lived as foragers, traveling in extended family groups in search of food. In many groups, men hunted while women gathered plants, though roles likely varied. They set up camps for weeks or even months at a time, but they did not have permanent homes.
About 12,000 years ago, the Earth’s climate warmed significantly, but scientists are not sure why. Early humans remained in camps longer as food became more abundant. About 10,000 years ago, some groups began to plant seeds and domesticate animals. Their camps evolved into the first villages as the Agricultural Revolution took hold.
