The skull was unlike anything seen before, having a flattened cranium with a heavy brow ridge above large eye sockets.
What was the climate like when people first came here?
Northern Illinois has an unusual climate history due to its latitude and geology.
The Chicago region in particular was once under the southern edge of the Wisconsinan ice sheet.
When this massive ice sheet started to retreat 18,000 years ago, it depressed the land and created a widen basin: Much of the city of Chicago lies on beach and lake sediments deposited by Lake Michigan and its predecessor glacial Lake Chicago.
Carbon 14 is continually being created in the Earth's atmosphere by the interaction of nitrogen and gamma rays from outer space.
Since atmospheric carbon 14 arises at about the same rate that the atom decays, the Earth's levels of carbon 14 have remained constant.He was considered to be the brutish ancestor link to man in the evolution chain, the intermediate stage between man and ape.near Dusseldorf, Germany uncovered a skull and bones.Paleo Indian had immigrated across the Bering Sea by the land bridge of the Aleutian Island chain (known as Beringia) from Siberia into North America and followed a corridor south between the retreating ice sheets, perhaps to hunt wooly mammoth.A more recent theory propose prehistoric Solutreans of Ice Age France also sailed west to America across the Atlantic Ocean along the south ridge of the polar ice cap more than 18,000 years ago.Following a strict biblical chronology, Egyptian civilization cannot predate creation, nor can the pyramids be pre-Flood constructions.
