Resumen
Nuevas técnicas de datación revelan que el arte rupestre indonesio es más antiguo de lo que se pensaba. Una escena de caza tiene ahora más de 50.000 años, y una escena narrativa es el arte representativo más antiguo del mundo.
Área de la Ciencia:
- Arqueología
- Geocronología
- Paleoantropología
Sus antecedentes:
- El área kárstica de Maros-Pangkep en Sulawesi del Sur, Indonesia, es conocida por el arte rupestre antiguo.
- La datación anterior de este arte se basó en el análisis de la serie de uranio en solución (serie U) de los depósitos de calcita superpuestos.
Objetivo del estudio:
- Para volver a fechar el arte rupestre temprano en Maros-Pangkep usando una nueva técnica de imágenes de la serie U de ablación láser.
- Establecer edades mínimas más antiguas para el arte rupestre e identificar los primeros ejemplos de arte representativo y narración visual.
Principales métodos:
- Aplicación de imágenes de la serie U de ablación láser para una mayor precisión espacial en la datación de depósitos de calcita.
- La nueva datación del arte previamente analizado y la datación de nuevos motivos en múltiples sitios de Maros-Pangkep.
Principales resultados:
- Una escena de caza en Leang Bulu' Sipong 4 fue re-datada a un mínimo de 50.2 ± 2.2 ca, significativamente más antigua que la estimación anterior de 43.9 ca.
- Una escena narrativa recientemente descrita en Leang Karampuang fue fechada en un mínimo de 53.5 ± 2.3 ka.
- Esta escena narrativa, que representa figuras humanas y un cerdo, representa el primer ejemplo conocido del mundo de arte figurativo y narración visual.
Conclusiones:
- El arte figurativo y la narración visual del Homo sapiens tienen orígenes más profundos de lo que se reconocía anteriormente.
- Las imágenes de la serie U de ablación láser proporcionan edades mínimas más precisas y más antiguas para el arte rupestre antiguo.
- Los hallazgos retrasan la línea de tiempo para la creación de imágenes humanas complejas y la representación narrativa.

01:50Global Climate Change
24.3K
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.

02:56The Fossil Record
25.1K
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...

During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

02:35What is Evolutionary History?
36.4K
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.

02:48Radioactive Decay and Radiometric Dating
33.8K
Radioactivity is a spontaneous disintegration of an unstable nuclide and is a random process, as all the nuclei in the sample do not decay simultaneously. The number of disintegrations per unit time is called the activity (A), which is directly proportional to the number of nuclei in the sample. The decay constant (λ) is an average probability of decay per nucleus in unit time.

01:26Bone Markings
5.2K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
