. “We observe different individual responses when it comes to handling different tools, as well as gender differences”, comments Emiliano Bruner, lead author of this paper, entitled Cognitive archaeology, body cognition, and hand-tool interaction, which highlights the importance of body and technology as integral parts of the same cognitive process. In this paper, undertaken in collaboration with the Museum of Human Evolution (MEH), in Burgos, and the company Sociograph, of Valladolid, in which analysis of electrodermal activity is proposed as a new tool for neuroarchaeological research, an extensive review is also presented of the evidence from paleoanthropology and archaeology for how the parietal cortex in the brain and visuospatial capacities have evolved in the human genus. Senescence or biological aging is the general deterioration

of the physiological functions of an Guam Email List organism that makes us more susceptible to disease and ultimately leads to death. It is a complex process in which many genes are involved. Life span varies greatly between different animal species. Thus, for example, the life span of a fly is four weeks, that of horses about thirty years, and some hedgehogs reach up to two centuries. What makes such a wide range of life expectancies in nature? This is one of the fundamental questions that most intrigues biologists. In the case of humans, we can potentially live 120 years, while the primate species closest to ours live half. In order to explain this difference, researchers from the Institute of Evolutionary Biology ( IBE ), a joint center of UPF and CSIC, the Center for Genomic Regulation ( CRG ), the University of Bristol and the University of Liverpool have identified

some of the genes that may have been key in the lengthening of life in our species and that have been produced, in parallel, in primates that have a longer life. The study is published in the journal Molecular Biology & Evolution , and stars on the cover. They have identified some of the genes that may have been key in the lengthening of life in our species In the work, the researchers studied the genomes of seventeen species of primates, including humans . From the perspective of aging, primates are interesting because, despite being very close, there are profound differences between some species and others in terms of life expectancy. Thus, of the species studied, only three – humans and two macaques – lived much longer than the common ancestor, which shows that “they have undergone a relatively rapid process of vital lengthening”, explains Arcadi Navarro , ICREA research professor at the IBE and study leader. The genes of these three species were compared with
