Phylogenomic analyses of 2,786 genes in 158 lineages support a root of the eukaryotic tree of life between opisthokonts and all other lineagesMario Cerón-Romero, Laura Katz, Miguel Fonseca, Leonardo De Oliveira Martins & David Posada
Advances in phylogenetic methods and high-throughput sequencing have allowed the reconstruction of deep phylogenetic relationships in the evolutionary history of eukaryotes. Yet, the root of the eukaryotic tree of life remains elusive. The most ‘popular’ (i.e. in textbooks and reviews) hypothesis for the root is between Unikonta (Opisthokonta + Amoebozoa) and Bikonta (all other eukaryotes), which emerged from analyses of a single gene fusion and a limited sampling of eukaryotic lineages. Subsequent highly-cited studies based...
Data from: Delegation to artificial agents fosters prosocial behaviors in the collective risk dilemmaElias Fernandez Domingos, Inês Terrucha, Rémi Suchon, Jelena Grujić, Juan C. Burguillo, Francisco C. Santos & Tom Lenaerts
Home assistant chat-bots, self-driving cars, drones or automated negotiation systems are some of the several examples of autonomous (artificial) agents that have pervaded our society. These agents enable the automation of multiple tasks, saving time and (human) effort. However, their presence in social settings raises the need for a better understanding of their effect on social interactions and how they may be used to enhance cooperation towards the public good, instead of hindering it. To...
Structure and stability constrained substitution models outperform traditional substitution models used for evolutionary inferenceUgo Bastolla, Ivan Lorca & Miguel Arenas
The current knowledge about how protein structures inﬂuence sequence evolution is rarely incorporated into substitution models adopted for phylogenetic inference, which are commonly based on independent with the same substitution process and ignore the known variation of the evolutionary rates across sites with diﬀerent structural properties. In previous works, we presented site-speciﬁc substitution models of protein evolution based on selection on the folding stability of the native state (Stab-CPE), which predict more realistically the evolutionary...
Data from: A phylogenetic study to assess the link between biome specialisation and diversification in swallowtail butterfliesSara Gamboa, Fabien L. Condamine, Juan L. Cantalapiedra, Sara Varela, Jonathan Pelegrín, Iris Menéndez, Fernando Blanco & Manuel Hernández Fernández
The resource-use hypothesis, proposed by E.S. Vrba, states that habitat fragmentation caused by climatic oscillations would affect particularly biome specialists (species inhabiting only one biome), which might show higher speciation and extinction rates than biome generalists. If true, lineages would accumulate biome-specialist species. This effect would be particularly exacerbated for biomes located at the periphery of the global climatic conditions, namely, biomes that have high/low precipitation and high/low temperature such as rainforest (warm-humid), desert (warm-dry),...
