Published on: July 3, 2016
Resumen
La investigación arqueológica en Jordania revela antiguas estrategias de adaptación humanas. La transhumancia, un patrón de migración estacional, se empleó desde el Paleolítico Medio, con sitios utilizados en diferentes estaciones y elevaciones.
Área de la Ciencia:
- Arqueología paleolítica Arqueología paleolítica
- Reconstrucción paleoambiental de la reconstrucción paleoambiental de la reconstrucción paleoambiental de la reconstrucción paleoambiental de la reconstrucción paleoambiental de la reconstrucción paleoambiental
Sus antecedentes:
- 109 sitios arqueológicos descubiertos en el sur de Jordania abarcan desde el Paleolítico Inferior hasta el Calcolítico (150-6 ka).
- Se identificaron dos tipos de sitios distintos, campamentos a largo plazo y efímeros, desde el Paleolítico Medio (70 ka) en adelante.
Objetivo del estudio:
- Investigar las estrategias adaptativas de las poblaciones humanas prehistóricas en el sur de Jordania.
- Comprender el uso estacional del sitio y las influencias ambientales en los patrones de asentamiento.
Principales métodos:
- Análisis del área del sitio, el grosor del depósito, la densidad de artefactos y las características arqueológicas.
- Examen de los entornos naturales (elevación, exposición) y pruebas estacionales (fitolitos, incrementos de cemento).
Principales resultados:
- Los sitios a largo plazo (invierno / estación húmeda) exhiben áreas más grandes, depósitos más gruesos y más características que los sitios efímeros (temporada cálida / seca).
- La evidencia sugiere una estrategia de transhumancia, con un cambio en las elevaciones de los campamentos de invierno después del Pleistoceno debido al cambio climático.
Conclusiones:
- Las poblaciones prehistóricas en Jordania utilizaron una estrategia de transhumancia, adaptándose a los cambios ambientales estacionales.
- Los cambios climáticos al final del Pleistoceno alteraron significativamente los patrones de asentamiento y el uso estacional del sitio.

02:35What is Evolutionary History?
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.Phylogenetic trees illustrate the evolutionary relationships among these organisms. Scientists infer organisms’ common ancestry by evaluating shared morphological and genetic characteristics. Together, the fossil...
02:56The Fossil Record
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...
02:31Habitat Fragmentation
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.
01:12Ecological Niche
Microorganisms occupy diverse habitats and perform essential ecological functions that are defined by their ecological niches. A microbial niche encompasses the organism’s mode of survival, including resource acquisition, reproduction, and interactions with other species in its environment. This concept is vital for understanding microbial community dynamics, biogeography, and ecosystem functionality.The fundamental niche of a microorganism includes the full spectrum of environmental...
02:02Ecological Niches
All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.Multiple species cannot occupy the exact same niche within their habitat. If the niches of two or more species overlap to a large extent, the competitive exclusion principle dictates that one species will outcompete the other, forcing it to...
01:50Global Climate Change
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
