OUR VISION

To contribute to the understanding of the evolutionary and ecological processes that generate and maintain biological diversity, considering that this knowledge helps to the conservation of species and ecosystems in Ecuador and the Neotropics. 

 

OUR MISSION

In the Evolutionary Biology Laboratory we seek, as Dobzhansky proposed, to understand the biology of organisms in the light of evolution. Therefore, we address a wide spectrum of research interrogations on phylogenetic and its relationship with other issues such as ecology, physiology, biogeography and conservation of species. The organisms we study are also diverse, ranging from vertebrates to protozoa. Our research goes beyond borders, allowing us to understand evolutionary patterns and processes from local to continental scales. This is only possible thanks to an excellent supporting staff and students as well as a wide network of national and international colleagues.
