Entendiendo la movilidad humana mediante tecnologías espaciales: el papel de las áreas naturales de tránsito en el Suroeste de la Península Ibérica durante la Prehistoria Reciente

Open access
Murrieta-Flores, Patricia·2012·Trabajos de Prehistoria

Abstract

Investigaciones arqueológicas, históricas y etnográficas han demostrado como los ambientes de montaña tienen una profunda influencia en las dinámicas socioculturales de las comunidades que viven en ellos y en sus áreas vecinas. El desarrollo de estas sociedades tiende a producirse en los márgenes, usualmente lejos de los centros de poder político. Esta marginación se extiende también a la circulación en estas regiones, donde las cordilleras suelen constituir poderosos obstáculos debido a su configuración natural que juega un papel central en sus estrategias, comercio y movimiento humano. Durante la Prehistoria Reciente, la constitución de Sierra Morena Occidental (España) moldeó tanto las vías de tránsito a través de las montañas, como las rutas históricas de comunicación que atraviesan Andalucía. Utilizando una metodología de Sistemas de Información Geográfica diseñada específicamente para identificar características en el paisaje de particular relevancia para el movimiento humano (como corredores naturales, puntos de cruce y áreas naturales de tránsito), se examinó el papel que la accesibilidad del terreno tuvo para las comunidades de esa región durante la Prehistoria Reciente. Mediante este análisis concluimos que la ubicación de sus hábitats y lugares simbólicos se encuentran estrechamente relacionados con corredores naturales, posiblemente debido a una creciente importancia de las actividades de pastoreo.

TL;DR

Using GIS-based morphometric, cost-surface, least-cost-path, and line-density analyses, this paper examines whether late prehistoric sites in western Sierra Morena were located near natural corridors. It concludes that settlements and symbolic places are strongly associated with natural areas of transit, possibly reflecting an increasing importance of herding and seasonal mobility toward the Bronze Age.

Key findings

  • Most archaeological sites and monuments, regardless of chronology, fall within areas identified as natural corridors; statistical tests rejected the null hypotheses at a 0.05 significance level for all periods except LBA funerary monuments, whose sample was too small.
  • Settlement-corridor coincidence was 73.33% for Copper Age, 81.25% for Early Bronze Age, and 87.5% for Late Bronze Age; funerary-site coincidence was 88.24% for Copper Age, 75% for EBA, and 33% for LBA.
  • Association with land historically used for pasturage/herding was 25% for Copper Age settlements and 65.6% for EBA settlements, suggesting Bronze Age groups more regularly sought herding-suitable spaces and seasonal movement.
  • Megalithic monuments mostly fell within 500–1000 m of calculated corridors, while EBA funerary places were even closer, within 0–500 m, supporting their possible role as landscape markers.

Methods

  • Study area: western Sierra Morena, specifically Sierra de Huelva and Sierra Norte de Sevilla, Spain; landscape-scale analysis covered 5,261 km² and 398 archaeological sites from Copper Age to Late Bronze Age.
  • GIS workflow combined morphometric analysis of a 10 m DTM to identify passes/passageways, cost surface analysis with anisotropic friction and river-crossing costs, least cost paths from 36 access points, and line density analysis to define natural corridors.
  • Spatial association between sites and corridors was tested with one-sample Kolmogorov–Smirnov tests at a 0.05 significance level, using 500 m buffers from corridors.

Limitations

  • The paper states that movement models are usually imperfect and depend on DTM spatial resolution, cost equations, LCP algorithms, and many physical and social variables; results are a starting point for further questions and methodological improvement.
  • It also notes limitations of the archaeological record: few prehistoric sites in the region have been extensively excavated and published, faunal evidence is hampered by high soil acidity, and the LBA funerary sample is too small for robust statistical testing.
  • Evident from the text: the analysis identifies spatial association, not direct proof of prehistoric movement or herding practice, and the author calls for further paleoenvironmental research and excavation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-11-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-11-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
