PROVIDENCE, R.I. [Brown University] — Aggregating nearly the entire landmass of Earth, Pangaea was a continent the likes our planet has not seen for the last 200 million years. Its size meant there was a lot of space for animals to roam, for there were few geographical barriers, such as mountains or ice caps, to contain them.
Dec. 23, 2011 — Evidence of the single-celled ancestors of animals, dating from the interval in Earth's history just before multicellular animals appeared, has been discovered in 570 million-year-old rocks from South China by researchers from the University of Bristol, the Swedish Museum of Natural History, the Paul Scherrer Institut and the Chinese Academy of Geological Sciences.
By Philip Guelpa 27 December 2011 The recently reported results of genetic research comparing samples of fossil Neanderthal DNA with that of modern populations around the world appear to indicate that modern humans outside of Africa derive some portion of their genetic material from Neanderthals. This finding, if supported by further research, has important implications, not only in answering the longstanding question of what happened to the Neanderthals, but more importantly for our understanding of the relative weight of cultural versus biological adaptation in human evolution. Since the discovery of human-like fossils in the Neander Valley of German in the mid-19 th century, anthropologists and others have debated the question of how closely Neanderthals, as this fossil group was named, were related to modern humans. The question soon became entangled in the larger issue of biological evolution in general after the publication of Darwin’s On the Origin of Species .
In 2002, archaeologists uncovered an isolated grave just outside the log wall of a fort built on an island in the James River almost four centuries earlier. Who was buried there?
