Pompeu Fabra University and the Institute of Evolutionary Biology are launching the project NEWS: Prediction of Technological Innovation in Culturomic Networks, aimed at understanding the origins of innovation through the development of a theory of technological evolution.
IBE Scientists have discovered that a gecko subspecies could actually contain up to 14 different species. These species are called cryptic because it is necessary to analyse them genetically to be able to distinguish one from the others. These results are very important since, once differentiated, it has been seen that some of them may be in endangered.
The rate of genomic adaptation is determined by the rate of environmental change, the availability of beneficial mutations, and the efficiency of positive selection. Scientists conclude that the impact of selection on the genomic diversity of a species increases with the effective population size, most likely due to the differential influx rate of beneficial mutations.
Natural selection favours fragile and unhealthy old age if it is due to mutations that are beneficial during childhood. As of 40-50 years of age, natural selection is blind because we have already passed on our genes, whether beneficial or not, to our descendants. Knowing the genes and mutations involved in ageing may help to develop new strategies for the treatment of age-related diseases.
On 7 and 8 March, on the occasion of a B-Debate, an initiative promoted by Biocat and Obra Social “la Caixa”, national and international experts in Artificial Intelligence will come together at the CosmoCaixa to talk about the dreams, the riscks and the reality of AI. This B-Debate organized by Luc Steels, principal investigator at the Isntitute of Evolutionary Biology.
Scientists at the Institute of Evolutionary Biology find common features in genes associated with diseases. The study, published in the journal Human Molecular Genetics, suggests a degree of biological importance in the genome depending on the linkage of genes to disease.
IBE participates practical course “Uncovering the hidden diversity of the oceans” run by the Multicellgenome Lab. In this course students will be the first one to study a new species of Sphaeroforma that was isolated from the gut of a crustacean from the Arctic Ocean.
Minister of the Catalan Government, Raül Romeva, has met with family members of Vicente Santolaria to present them with the archaeological summary and a genetic identification report. Genetic identification, led by the company Tríade Serveis Culturals, involved Pompeu Fabra University, the Autonomous University of Barcelona and the Institute of Evolutionary Biology.
Genomic analysis of the Iberian lynx confirms that it is one of the species with the least genetic diversity among individuals, which means that it has little margin for adaptation. The research, which is published today in Genome Biology, has been coordinated by scientists at the Doñana Biological Station (CSIC). The use of new genomic resources will contribute to optimizing management aimed at preserving the maximum genetic diversity.

Its inhabitants have markers in the genome of the major migratory flows. As a result of the genetic impact of migrations, Berbers and Arabs are not as genetically different as was thought. The study was led by David Comas at the Institute of Evolutionary Biology of Barcelona.
At the Institute of Evolutionary Biology (CSIC-UPF) we are very excited to welcome director Alexis Gambis on Wednesday 16th of November at 4.30 PM at the PRBB auditorium for the screening of the film "The Fly Room". Original version movie (English) with subtitles in Spanish. Admision is free and open to everybody in a first-come first-served basis. Please spread the word between your colleagues.
This is the first Spanish network of excellence on adaptation genomics, is coordinated by Professor Julio Rozas, from the University of Barcelona, and participated by Elena Bosch, Josefa González, and Iñaki Ruiz-Trillo from the Institute of Evolutionary Biology. The network, funded by the Ministry of Economy and Competitiveness, is made up of 24 laboratories from 11 research centers in the country and will drive the collaboration of the research teams in evolutionary genomics and will promote dissemination of scientific advances to all society.
An international team of researchers led by Tomàs Marquès-Bonet reveals for the first time the existence of ancient gene flow between chimpanzees and bonobos, man’s closest living relatives. The study is based on the analysis of 75 complete genomes from the two species covering 10 African countries and has strong implications for chimpanzee conservation.
El diumenge dia 6 de novembre se celebrarà el proper Esmorzar de Ciència amb un cartell de luxe: Eudald Carbonell i Tomàs Marquès. El restaurant obrirà les portes a les 9 del matí per començar l’esmorzar, a les 10 s’inicia el monòleg a càrrec de The Big Van Theory, i acte seguit comença la tertúlia a càrrec dels experts i el moderador. L’esmorzar de forquilla amb tertúlia té un preu de 25€.
The first animals evolved from their single-celled ancestors around 800 million years ago, but new evidence suggests that this leap to multi-celled organisms may not have been quite as dramatic as scientists once assumed. In a Developmental Cell paper, IBE researchers demonstrate that the single-celled ancestor of animals likely already had some of the mechanisms that animal cells use today to develop into different tissue types.
The scientists looked at the morphology [structure and form] of geckos from the Hajar Mountains of the UAE and Oman that are classified as belonging to the Asaccus caudivolvulus species. A complex computer analysis of the data led the scientists to conclude that A caudivolvulus is made up of creatures from three species.
Iñaki Ruiz-Trillo and colleagues analyze the diversity of a group of animals that are crucial to understand the origin of bilaterian symmetry: the Xenacoelomorpha, a group of morphologically simple worms that are known to occupy a pivotal phylogenetic position between non-bilaterian and bilaterian animals.
Work, led by Carles Lalueza-Fox, recovers DNA from two strains of malaria from old samples from the Ebro Delta in Spain. The results reveal the origins of P. vivax y P. falciparum, and help us comprehend the mutations which have become resistant to numerous drugs.
