The ocean was often called the Sea of Magellan in his honor until
14028-724: The Philippines already in 7000 BCE. Additional earlier migrations into Insular Southeast Asia, associated with Austroasiatic-speakers from Mainland Southeast Asia, are estimated to have taken place already in 15000 BCE. At around 1300 to 1200 BCE, a branch of the Austronesian migrations known as the Lapita culture reached the Bismarck Archipelago , the Solomon Islands , Vanuatu , Fiji , and New Caledonia . From there, they settled Tonga and Samoa by 900 to 800 BCE. Some also back-migrated northwards in 200 BCE to settle

The Red Hill Bay project will be used as an example to monitor the amount of time it takes for wildlife and fish to re-establish themselves back into this natural habitat in order to predict the ecological success for future potential Salton Sea restoration projects. As of 2021, the project area remains flat, dry and dusty with budget issues and local politics delaying
14362-476: The U.S. entered World War I. Although often viewed as an internal conflict, the revolution had significant international elements: Germany attempted to get Mexico to side with it, sending a coded telegram in 1917 to incite war between the U.S. and Mexico, with Mexico to regain the territory it lost in the Mexican-American War but Mexico remained neutral in the conflict. In 1916, the winners of
