Knowledge claims that are based more on universal discoveries and natural science can be found in the subjects of philosophy, chemistry, physics, biology, mathematics, and geology.
The term "ethnogeology" first enters the geological literature through the work of John Murray of the University of Manitoba in Winnipeg, Canada in the mid-1990s by virtue of his studies of the Northern Cree First Nation geological worldviews in the Province of Manitoba in Canada.
[1][2] At that time, a cadre of geologists and geoscience educators - particularly Dr. Steven Semken of Navajo Community College in Shiprock, New Mexico and colleagues - were examining the interesting connections among Native American traditional knowledge, geoscience concepts, and the unique vision of planet Earth's history as articulated by indigenous ethnogeological wisdom (see references below).
One global example of geological knowledge over thousands of years is the making of rock tools and arrowheads.
Flint, obsidian, chert, copper and quartz were some examples of useful rocks or minerals for thousands of years.
