James Watson, a UA anthropologist, has published chapters describing how long-term environmental trends encourage stable adaptations within local environments.
Human/environment interactions have a history as long as the existence of our species on the planet.
Hominid ancestors began polluting their environment nearly 700,000 years ago with the control of fire, and humans have not looked back since.
The modern phenomenon of global warming is very likely the direct result of human pollution and destruction of the environment, said James Watson, a University of Arizona assistant professor in the School of Anthropology. (more…)
A NASA-led research team has confirmed what Walt Disney told us all along: Earth really is a small world, after all.
Since Charles Darwin’s time, scientists have speculated that the solid Earth might be expanding or contracting. That was the prevailing belief, until scientists developed the theory of plate tectonics, which explained the large-scale motions of Earth’s lithosphere, or outermost shell. Even with the acceptance of plate tectonics half a century ago, some Earth and space scientists have continued to speculate on Earth’s possible expansion or contraction on various scientific grounds.
Now a new NASA study, published recently in Geophysical Research Letters, has essentially laid those speculations to rest. Using a cadre of space measurement tools and a new data calculation technique, the team detected no statistically significant expansion of the solid Earth. (more…)
With the beginning of Ramadan, the Ninth Month of the Islamic Calendar, come hot debates, as to whether Moslems should be allowed to slit the throats of sheep in public, to make the call to prayer (Adhan) in non-Moslem communities, to build a Mosque near Ground Zero.
