The three things the kansas nebraska act said

Although initially concerned about the political fallout, President Franklin Pierce gave Douglas and his southern allies his support. The “Appeal of the Independent Democrats,” signed by such Free-Soilers as Salmon P. Chase and Charles Sumner and published in many northern newspapers, attacked Pierce, Douglas, and their supporters for breaking a sacred compact by repealing the Missouri Compromise.

The act passed Congress, but it failed in its purposes. By the time Kansas was admitted to statehood in 1861 after an internal civil war, southern states had begun to secede from the Union. The Independent Democrats and many northern Whigs abandoned their affiliations for the new antislavery Republican party, leaving southern Whigs without party links and creating an issue over which the already deeply divided Democrats would split even more. The railroad was eventually built but not along the route Douglas wanted and with funds voted by a Republican Congress during a Republican Civil War administration.

answer; i believe the two groups were irish immigrants and chinese immigrants;

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."
