Casting aside old dogmas, these researchers are finding that people arrived significantly earlier than previously believed, and adapted rapidly to environments from the arid western coastline to the Amazon jungle and the frosty heights of the Andes.
By teaming up with geologists, climate scientists and other researchers, archaeologists are gaining a clearer picture of what the ancient environments were like and how people migrated across the landscape — clues that are leading them to other ancient occupation sites.
Having a relationship with someone is important in all cultures, however the process of dating is different according to countries.
Thus, culture affects the way people date, suggesting various kinds of dates from heavily supervised meetings to evenings spent at the movies.
The findings are significant because they suggest that humans inhabited North America well before the last ice age more than 20,000 years ago, a potentially explosive revelation in American archaeology.
However, by the turn of the 20th century we find the word being used to describe lower-class men and women going out socially to public dances, parties and other meeting places, primarily in urban centers where women had to share small apartments and did not have spacious front parlors in their homes to which to invite men to call.The landscape looks bleak, but Rademaker views it through the eyes of the people who built a fire in the rock shelter, named Cuncaicha, about 12,400 years ago.These hunter-gatherers were some of the earliest known residents of South America and they chose to live at this extreme altitude — higher than any Ice Age encampment found thus far in the New World."The dates could actually be older," Goodyear says."Fifty-thousand should be a minimum age since there may be little detectable activity left." The dawn of modern homo sapiens occurred in Africa between 60,000 and 80,000 years ago.
