Insular gigantism and dwarfism in a snake, adaptive response or spandrel to selection on gape size?
In biology, spandrels are phenotypic traits that evolve through their underlying developmental, genetic, and/or structural links to another trait under selection1, 2, 3. Despite the importance of…

An ancient adaptive episode of convergent molecular evolution confounds phylogenetic inference
Convergence can mislead phylogenetic inference by mimicking shared ancestry, but has been detected only rarely in molecular evolution. Here, we show that significant convergence occurred in snake a…

Selfish and Altruistic Bacterial Populations Maximize Fitness Under Stress by Local Segregation
Landscapes in ecology have a profound influence on the adaption and evolution of competing populations for resources. We are interested in how altruistic populations survive in the presence of self…

Differences of morphological and ecological characters among lineages of Chilean Rhinocryptidae in relation an sister lineage of Furnariidae.
Eight species of Rhinocryptidae are recognized from Chile. Moreover, morphological, ecological and behavioral differences among two lineages of Scytalopus and two species of Pteroptochos are un…

A visual sense of number
Evidence exists for a non-verbal capacity to apprehend number, in humans1 (including infants2,3) and in other primates4-6. Here we show that perceived numerosity is susceptible to adaptation,...
