Kernel Density Estimate (KDE) summaries of Bayesian phase models demonstrate the following aspects of regional cultural dynamics: the earliest settlements began in the Preceramic ca. 6000 BCE and are found on the coast; the Paracas culture was established ca. 900 BCE and cultural development was first focused in the north and then spread south; a reverse direction of cultural influence is found during the Nasca culture when innovation began in the south and spread north; an early mixture of Late Nasca/local Loro culture is found in Nasca (510–720 CE) followed by the spread of Loro elsewhere and the establishment of intrusive highland Wari colonies that peaked in the mid-9th century CE; and the Late Intermediate Period was variable throughout the region in terms of timing and duration, reflecting a turbulent period. The results of the study reveal strong temporal overlap in the ceramic styles indicating they are not purely sequential and consequently are inadequate as chronological markers on a regional level.

We calibrate dates with a bespoke calibration curve mixture specific to Machu Picchu.

Anchoring Inca history to this radiocarbon chronology allows us to explore the ethnohistoric sources in a new light.

Juxtaposing that timespan with a compilation of Central Andean radiocarbon dates identifies contemporary non-participatory sites, enabling characterization of the sociopolitical milieu within which the Chavín Phenomenon emerged, flourished, and faded.

The collected data indicate significant variations in the composition and density of pollen in response to climate-induced and anthropogenic ecological changes throughout the northwest India transect. The palynological studies from eastern Rajasthan shows high forest elements in comparison to western Haryana and western Uttar Pradesh. In addition, the palynological data was juxtaposed with other biotic proxies such as diatom and isotopic studies, along with geochemical proxies and paleomagnetic data of the surface lake sediments. The presence of marker pollen taxa including Cerealia type Poaceae, Chenopodiaceae, and Brassicaceae, allows for distinct recognition of anthropogenic activities throughout the whole transect. The diversity and distribution of diatoms also support the palynological data in response to climate-induced and anthropogenic ecological changes. Furthermore, grain size, geochemistry (TOC/TN ratio with stable carbon isotope), and magnetic susceptibility data offer crucial insights about the sediment's depositional settings and general mineralogical composition. Stable carbon isotope data shows C₃ dominance in relatively humid areas and C₄ dominance in semi-arid areas, suggesting climate-driven control over sediment organic matter composition. Canonical correspondence analysis (CCA) indicates that biotic variables (pollen, diatom, stable isotopic composition) are significantly controlled by modern precipitation and temperature. Redundancy analysis reveals a significant influence of current average temperature and precipitation on major element oxide variations in surface lake sediments. Therefore, we propose using palynological, stable carbon isotope, diatom data, along with grain size, environmental magnetism, and geochemistry, to establish a multiproxy modern analogue for quantitative palaeoclimatic reconstructions.
