Most of the evidence we have about early humans comes from Cro-Magnon.

Explanation:

The Cro-Magnon Man is an extinct hominid very similar to today's humans. Its name is that of the rock shelter in France where several skeletons of this species were discovered in 1868.

The Cro-Magnon lived with the Neanderthal during the end of the last glaciation, from about 35,000 years ago to about 10,000, settling in various parts of Europe.

Although the bones of his legs were a little more robust, his characteristics were very similar to those of the modern human being. That's why many archaeologists prefer to call it 'Early Modern Human' instead of 'Cro-Magnon' or Homo Sapiens

The Cro-Magnon Man had the ability to make instruments of stone, bone and ivory. He also used animal teeth and horns. His handling of different materials and his ability to think allowed him to make sharp blades, fishing rods, bows, and arrows. The Cro-Magnones cut down trees with axes and then built homes and canoes, and also used to wear clothes and ornaments on their bodies. Caves have been found with cave paintings that were made by members of this species.

The Cro-Magnones tools allowed them to dominate their environments. It is thought that the superiority of this hominid was a factor that began the process of extinction of the Neanderthal.
