“History and geography
The dating of the Norte Chico sites has pushed back the estimated beginning date of complex societies in the Peruvian region by more than one thousand years. The Chavín culture, circa 900 BC, had long been considered the first civilization of the area. It is still regularly cited as such in general works.
The discovery of Norte Chico has also shifted the focus of research away from the highland areas of the Andes and lowlands adjacent to the mountains (where the Chavín, and later Inca, had their major centers) to the Peruvian littoral, or coastal regions. Norte Chico is located in a north-central area of the coast, approximately 150 to 200 km north of Lima, roughly bounded by the Lurín Valley on the south and the Casma Valley on the north. It comprises four coastal valleys: the Huaura, Supe, Pativilca, and Fortaleza; known sites are concentrated in the latter three, which share a common coastal plain. The three principal valleys cover only 1,800 km², and research has emphasized the density of the population centers.
The Peruvian littoral appears an "improbable, even aberrant" candidate for the "pristine" development of civilization, compared to other world centers.[1] It is extremely arid, bounded by two rain shadows (caused by the Andes to the east, and the Pacific trade winds to the west). The region is punctuated by more than 50 rivers that carry Andean snowmelt. The development of widespread irrigation from these water sources is seen as decisive in the emergence of Norte Chico; since all of the monumental architecture at various sites has been found close to irrigation channels.
The radiocarbon work of Jonathan Haas et al., found that 10 of 95 samples taken in the Pativilca and Fortaleza areas dated from before 3500 BC; the oldest, dating from 9210 BC, provides "limited indication" of human settlement during the Pre-Columbian Early Archaic era. Two dates of 3700 BC are associated with communal architecture, but are likely to be anomalous. It is from 3200 BC onward that large-scale human settlement and communal construction are clearly apparent.[2] Mann, in a survey of the literature in 2005, suggests "sometime before 3200 BC, and possibly before 3500 BC" as the beginning date of the Norte Chico formative period. He notes that the earliest date securely associated with a city is 3500 BC, at Huaricanga, in the Fortaleza area of the north, based on Haas's dates.”
>> Note the date anons and compare it with what we found in Mesoamerica, Ancient Egypt and Mesopotamia = ALL started to show SIGNS of “large-scale human settlements” = city-states, between the 4500 to 3000 BC. Approximately of course, it varies a bit from one region to another.
“Haas's early-third-millennium dates suggest that the development of coastal and inland sites occurred in parallel. But, from 2500 to 2000 BC, during the period of greatest expansion, the population and development decisively shifted toward the inland sites. All development apparently occurred at large interior sites such as Caral, though they remained dependent on fish and shellfish from the coast.[2] The peak in dates is in keeping with Shady's dates at Caral, which show habitation from 2627 BC to 2020 BC.[8] That coastal and inland sites developed in tandem remains disputed, however (see next section).
Circa 1800 BC, the Norte Chico civilization began to decline, with more powerful centers appearing to the south and north along the coast, and to the east inside the belt of the Andes. Norte Chico's success at irrigation-based agriculture may have contributed to its being eclipsed. Anthropologist Professor Winifred Creamer of Northern Illinois University notes that "when this civilization is in decline, we begin to find extensive canals farther north. People were moving to more fertile ground and taking their knowledge of irrigation with them".[3] It would be a thousand years before the rise of the next great Peruvian culture, the Chavín.”
