College Board Statement: Contact among Europeans, Native Americans, and Africans resulted in the Colombian Exchange and significant social, cultural, and political changes on both sides of Atlantic (Give 2 facts that prove the college board statement above true for europeans)
(Tell 2 things that changed for Europeans because of their contract with Americans?)

Facts  that prove the college board statement above true for europeans: The existence of agricultural products that are not native to Europe and the existence of colonies present today in the American continent, such as French Guiana for example.

Things that changed for Europeans because of their contract with the Americans: The Colombian exchange program provided great food stability in Europe, the establishment of large shopping centers with products collected from the colonies, such as the redwood trade found in Portugal.

Explanation:

The Colombian Exchange refers to the exchange of products and people between European and American individuals. This was because when Cristovão Colombo discovered the American continent, it allowed the exploitation of all the resources of that continent, which brought many natural products and riches to the European powers.

As evidence that the Colombian Exchange took place we can mention the existence of agricultural products that are not from Europe. Many fruits, vegetables, animals and spices were removed from America and taken to Europe, which created strong food stability in the old continent and provided the creation of strong shopping centers, such as the redwood trade in Portugual.

The Colombian exchange allowed European domination in America, which can be seen today with the existence of European territories in the American continent, such as French Guiana, in South America.

answer:   migrations were important in the neolithic period. "two major migrations passing through southeastern europe were confirmed by the means of archaeo-genetic studies."

the first migration was the early neolithic period -- 6,000 before common era (bce) -- when the first farmers, from anatolia -- asia minor -- spread through europe. the second migration occurred during the early bronze age (3,000-2,500 bce) when the so-called "steppe population," from the eurasian steppe, replaced much of northern europe's previous population.

the first farmers of northern and western europe passed through southeastern europe with limited hunter-gatherer genetic admixture, which occurs when two or more previously isolated populations begin interbreeding. however, some groups that remained mixed extensively -- without the male-biased, hunter-gatherer admixture that prevailed later in the north and west, according to latest discoveries. southeastern europe continued to be a nexus between east and west, with intermittent genetic contact with the steppe people up to 2,000 years before the migrations that replaced much of northern europe's population.

"in some places, hunter-gatherers and incoming farmers seem to have mixed very quickly," says iain mathieson, a geneticist at the university of pennsylvania, who was first author of the paper. "but, mostly, the two groups remained isolated, at least for the first few hundred years. these hunter-gatherers had been living there for thousands of years, and it must have been quite a shock to have these new people show up -- with a completely different lifestyle and appearance."
