Charles Darwin & Alfred Russel Wallace. A visit to the Galapagos Islands in 1835 helped Darwin formulate his ideas on natural selection. He found several species of finch adapted to different environmental niches. The finches also differed in beak shape, food source, and how food was captured. Natural selection is the mechanism suggested by Darwin for evolution. Because resources are limited in nature, organisms with heritable characteristics that favor survival and reproduction leave more offspring than their peers, causing the traits to become more common over generations.

By 1786, Americans realized that the Articles of Confederation, the first written constitution of the United States, had to be changed as, according to the Articles, Congress had no rights regarding the control of domestic affairs, such as taxation or commerce regulation. It depended on the financial help of the states, lacking money to pay soldiers for their service in the Revolutionary War or repay foreign loans. By 1786, the US was bankrupt. In 1787 a decision was made to write a new constitution, which was adopted the same year in Philadelphia.
