Resumen
Antiguos grabados en ocre rojo de Sudáfrica.
Área de la Ciencia:
- Arqueología Arqueología.
- La paleoantropología es la paleoantropología.
- Arqueología cognitiva Arqueología cognitiva
Sus antecedentes:
- Las imágenes abstractas y pictóricas del Paleolítico superior euroasiático (después de hace 35.000 años) se consideran evidencia del comportamiento humano moderno.
- El surgimiento del comportamiento humano moderno a menudo está vinculado a este período y región geográfica.
Objetivo del estudio:
- Para informar sobre grabados abstractos encontrados en piezas de ocre rojo.
- Para proporcionar evidencia del comportamiento humano moderno temprano en África.
Principales métodos:
- La datación por termoluminiscencia de líticos quemados para determinar la edad de las capas de la Edad de Piedra Media que contienen el ocre.
- La luminiscencia estimulada ópticamente data de una duna superpuesta para confirmar la integridad estratigráfica.
Principales resultados:
- Se descubrieron dos representaciones abstractas grabadas en piezas de ocre rojo.
- Los ocres grabados fueron fechados hace una media de 77.000 años.
- La integridad estratigráfica se confirmó con una edad de 70.000 años para una duna superpuesta.
Conclusiones:
- Estos hallazgos sugieren el surgimiento del comportamiento humano moderno en África.
- Este surgimiento es anterior al Paleolítico Superior de Eurasia por al menos 35.000 años.
- Los grabados abstractos representan algunas de las primeras evidencias conocidas de comportamiento simbólico.

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...
02:31Synteny and Evolution
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral chromosome underwent...

01:26Bone Markings
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...

01:15Quarrying of Stone
Quarrying is the process of extracting stone from a quarry, where specialized techniques are employed to remove large blocks of stone safely and efficiently. This process can involve controlled explosions or more precision-oriented methods such as cutting and drilling.
One common method involves using a diamond belt saw to cut large blocks from the quarry face. These blocks can be about 50 feet long and 12 feet high. After the initial vertical cut, drilling is performed at the base of the block.

01:20Evolutionary Psychology
Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the human psyche...
