Jan Bartek - AncientPages.com - Neanderthals are our closest extinct relatives and modern humans share 99.7% of their DNA. These intriguing beings were widespread across Europe and Western Asia for a long time, about 400,000 years ago, and they died out in Europe about 40,000 years ago.
Archaeological excavations and examinations of bones, caves and various ancient artifacts reveal that the Neanderthals were not as primitive as previously thought.

Scientists have previously discovered Neanderthals created jewelry, used plant-based medicine to treat pain and illness, and our long-gone ancestors buried their dead and developed spiritual beliefs. Now, a scientists decided to investigate whether the Neanderthals practiced meditation. Emiliano Bruner, a paleoneurologist at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), has led a study published in the journal Intelligence on how attention evolved in the human genus, which analyzes the paleontological and archaeological evidence that might shed light on the attentional capacity of extinct hominins.
This work proposes evolutionary changes in attention associated with the origin of the human genus and in Neanderthals, although only with Homo sapiens did this cognitive capacity attain a complexity which would profoundly revolutionize the behavior, technological complexity, and social structure of the species.
At the paleoneurological level, it assesses the role played by the evolution of the parietal lobes in attention, which can be defined as the capacity to maintain the cognitive process centered on one objective over time and in space in the face of internal and external distractions. At the archaeological level, the study evaluates information about the lithic industry and ecology of extinct hominins, considering those behaviors which could suggest evolutionary changes in working memory and visuospatial capacities.
The parietal lobes, which are a fundamental part of the attentional network, are also involved with the capacity for visual imagination associated to our particular skill for projection in the past (memories) and future (prediction). A mismatch between this projection capacity and the attentional network can affect the balance between the perception of the present moment and internal ruminations, which are the main causes of the high prevalence of stress, anxiety, and depression in human societies.
Mindfulness
Meditation is a form of cognitive training for the perceptual and attentional system and, over recent years, it has been widely studied in neuroscience because of its effects on the ability to direct and maintain the attention on the present moment.
In fact, the best-known form of meditation in Western society, mindfulness, is sometimes known as bare attention. "Considering the close relationship between attentional capacity and meditation, and to set the cat among the pigeons, it occurred to us to investigate whether extinct hominins might have been capable of practicing the selection and maintenance of mental stimuli," says Bruner.
Despite the importance of attention in all cognitive processes, this ability had not hitherto been looked at from a paleoanthropological perspective before this study, which was conducted in collaboration with Roberto Colom, of the Psychology Department at the Universidad Autónoma de Madrid.
The study was published in the journal Intelligence
