The Kennewick Man is the name given to the skeletal remains of a Paleoamerican man found in Kennewick, Washington, United States in 1996. The discovery of the Kennewick man challenged previously held ideas about immigration to America. The Kennewick man appears to be more closely related to Polynesians and the Ainu people of Japan than to Asian people who crossed over from Asia to Beringia. This suggests that there could have been more than one source of immigration of humans to America.
Nicholas Copernicus was a leader in the Scientific Revolution that published "On the Revolution of Heavenly Bodies" which concluded that the Earth revolves around the sun.
