Answer:
Darwin's main contribution to the theory of evolution was his theory of natural selection.
Explanation:
Natural selection is the phenomenon that some organisms from a particular population fit better into their environment, that is, are more likely to provide surviving offspring than less well-adapted organisms. The best adapted organisms will increasingly gain the upper hand within the population (survival of the fittest). It is thus one of the mechanisms of evolution. Mutations in, and recombinations of, the genetic material of the organisms cause the genetic variation in the population, allowing this selection.
Correct answer:
<h2>North Korea crossed the 38th parallel and invaded South Korea.</h2>
More detail:
At the end of World War II, Korea was divided between an area in the north that was under Soviet influence and in the south under American influence. When 90,000 North Korean troops crossed the 38th Parallel and attacked South Korea on June 25, 1950, US President Harry Truman ordered American troops moved from Japan to South Korea to protect the South against communist aggression. The United Nations also went into action. An emergency session of the UN Security Council was held -- from which the Soviet Union was absent because the USSR was boycotting the UN over the exclusion of communist China from the organization. Truman announced to the American people that he was authorizing sending US troops to prevent South Korea from being overtaken by communism. The UN Security Council met again and approved a US resolution approving the use of force against North Korea. Military forces in the Pacific theater, based in Japan, were deployed in the effort. There was no formal declaration of war by the US Congress, but Congress did vote to extend the draft and also authorized the president to call up military reserve personnel for duty.
