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.
Manifest destiny was the idea that the United States would stretch from sea to sea as a beacon of liberty. Texas had lots of American immigrants at the time and had a lot of slave plantations that could of extended the south. Texas also had recently broken free from Mexico, and was made by American settlers who made their government based on the US. So, because of all this, America decided to annex Texas and incorporate it into the Union.
Contrary to popular belief, Africa's civil wars are not due to its ethnic and religious diversity. Using recently developed models of the overall prevalence of civil wars in 161 countries between 1960-1999, we draw lessons with special reference to Africa, showing that the relatively higher prevalence of war in Africa is not due to the ethno-linguistic fragmentation of its countries, but rather to high levels of poverty, failed political institutions, and economic dependence on natural resources. We argue that the best and fastest strategy to reduce the prevalence of civil war in Africa and prevent future civil wars is to institute democratic reforms that effectively manage the challenges facing Africa's diverse societies.
