High mountain plant communities are one of the groups most vulnerable to global change. This phenomenon could threaten even the species that inhabit the highest levels, such as the Saxifraga longifolia (king’s crown), an endemic plant of the Pyrenees with sophisticated mechanisms to adapt to environmental changes. This is one […]

today ”. Goats and sheep in the Iberian Peninsula The ancient Neolithic sites of the Iberian Peninsula analyzed show that sheep and goats would have been the main component of the first herds of domestic animals in this westernmost area of the Mediterranean, also documenting a strong correlation between the […]
Neolithic communities in the northern Mediterranean began milk production between 9000 and 7000 years ago, from the beginning of agriculture, as soon as they introduced the domestication of animals. Milk was an important food, which would have contributed significantly to the expansion of the first peasant communities, providing them with […]
The diet of our most remote ancestors, the hominins, was richer and more varied than previously thought, according to an article published in the journal PLOS ONE signed by a team from the Biological Zoology and Anthropology Unit of the Department of Biology Evolutionary, Ecology and Environmental Sciences of the […]
maintained against other reinforcers, such as the money earned in the gambling task. “It is interesting to consider the evolutionary importance of the connection between the auditory and cortical areas and the more primitive subcortical system of emotional evaluation”, comments the researcher. This connection is very clear in musical hedonic […]
Researchers from the Brain Cognition and Plasticity group of the Bellvitge Biomedical Research Institute and the University of Barcelona (IDIBELL-UB), in collaboration with researchers from McGill University (Montreal), have published a new study in which they determine the brain mechanisms that explain the lack of sensitivity to music. The study, […]
A team of scientists, led by IRTA researchers, and in which the CRAG (Center for Research in Agrigenomics) and the University of Granada have collaborated, have carried out a project financed by MINECO, which is the first genetic, phenotypic study and of geographic adaptation carried out until today using traditional […]
twenty genes that do not work, and this does not appear to have any adverse consequences. When genes are expendable: less is more It is likely that the presence of redundant genes or the environmental conditions in which we currently live cause us to have genes that are not necessary. […]
those of the loss of coding genes by cell receptors (CCR5 and DUFFY), which make individuals more resistant to infection with the AIDS virus (HIV) and plasmodia than causes malaria. In nature, there are gene losses that have been beneficial to organisms: losses that have led to color changes in […]
are not stochastic, but there are biases in the missing genes (depending on the type of function of the gene or its location in the genome in different groups of organisms ), reinforces the importance of gene loss in the evolution of species ”. Losing to Win: An Evolutionary Paradox […]
