establishing itself in each of the species that have preceded us. From there other inferences can be made: Manual laterality implies cerebral laterality that is closely related to the ability to articulate language “, comments researcher Marina Lozano. The team has studied the cultural wear on anterior teeth, specifically the cut marks left on them as a result of their use as a third hand to hold materials while being cut with a lithic tool. These marks have been observed with the application of the scanning electron microscope. The gill theory was widely accepted when specific molecular markers of the fly wing were observed in the gills of crustaceans, suggesting the common origin of these structures. However, this type of analysis has its limitations, since it could be

a case of convergence rather than evolutionary Sweden WhatsApp Number List divergence. In the same way, the lack of a fossil record of the period in which the wings emerged has limited the analysis of this transitional stage. the greater the importance of coevolutionary selection among the interacting species, the greater the importance of indirect effects in general evolution through the network. Second, in mutualisms with multiple interacting species, the species that have fewer direct interactions are more influenced by indirect effects than by their direct interactions ”, comments Jordano. These reciprocities help to understand how different species evolve and, on the other hand, how other factors, such as climate change, influence their evolutionary character, facilitating or hindering these types

In a multidisciplinary study published in the journal Proceedings of the National Academy of Sciences (PNAS) , an international team of researchers, including several members of the Atapuerca Team, has combined archaeological, genetic and stable isotope data to condense 4000 years of Iberian biomolecular prehistory. The team has analyzed human remains from the north and south of Spain, among which the rich archaeological site of El Portalón stands out, which is part of the well-known set of sites of the Sierra de Atapuerca in Burgos and which itself records more than seven millennia of Iberian prehistory. The study also analyzed important sites such as the Cueva de los Murcielagos de Zuheros (Córdoba), from which the genome of a 7,245-
