Columbus succeeded in reaching the america’s because

Columbus led his three ships - the Nina, the Pinta and the Santa Maria - out of the Spanish port of Palos on August 3, 1492. His objective was to sail west until he reached Asia (the Indies) where the riches of gold, pearls and spice awaited. His first stop was the Canary Islands where the lack of wind left his expedition becalmed until September 6.

Once underway, Columbus benefited from calm seas and steady winds that pushed him steadily westward (Columbus had discovered the southern "Trades" that in the future would fuel the sailing ships carrying goods to the New World). However, the trip was long, longer than anticipated by either Columbus or his crew. In order to mollify his crew's apprehensions, Columbus kept two sets of logs: one showing the true distance traveled each day and one showing a lesser distance. The first log was kept secret. The latter log quieted the crew's anxiety by under-reporting the true distance they had traveled from their homeland.

This deception had only a temporary effect; by October 10 the crew's apprehension had increased to the point of near mutiny. Columbus headed off disaster by promising his crew that if land was not sighted in two days, they would return home. The next day land was discovered.

warfare was the primary means of cultural transmission in both regions.
