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.

relations between the soviet union and the united states were driven by a complex interplay of ideological, political, and economic factors, which led to shifts between cautious cooperation and often bitter superpower rivalry over the years. the distinct differences in the political systems of the two countries often prevented them from reaching a mutual understanding on key policy issues and even, as in the case of the cuban missile crisis, brought them to the brink of war.

the united states government was initially hostile to the soviet leaders for taking russia out of world war i and was opposed to a state ideologically based on communism. although the united states embarked on a famine relief program in the soviet union in the early 1920s and american businessmen established commercial ties there during the period of the new economic policy (1921–29), the two countries did not establish diplomatic relations until 1933. by that time, the totalitarian nature of joseph stalin's regime presented an insurmountable obstacle to friendly relations with the west. although world war ii brought the two countries into alliance, based on the common aim of defeating nazi germany, the soviet union's aggressive, antidemocratic policy toward eastern europe had created tensions even before the war ended.
