    • Presentation on Genetic Diversity
I am an evolutionary biologist interested in understanding speciation, mainly 'herps' (reptiles and amphibians). Multiple processes have generated modern species diversity. Our primary task is to combine as many data types as possible to recover the evolutionary history of a lineage (s) relative to several related species (a clade). Modern Zoologists rely on genetic and morphological data, including ecological and distributional information, to recover past evolutionary processes. Congruent and sometimes incongruent data help infer the factors driving the evolutionary divergence of populations, species, and potentially entire communities.
​In this context, oceanic islands and their inhabitant organisms are fascinating to study because islands exhibit constrained temporal windows and geographic distributions. Islands represent unparallel windows into evolution. Indeed, Charles Darwin's remarkable abstraction capabilities led him to hypothesize — after a brief visit to the Galápagos Archipelago — that natural selection was central to species origins and that species were not immutable entities. Charles Darwin dissected the distinct evolutionary forces mediating the birth of a new species. Ultimately, helping us to establish the connection between past and present. Whether one studies the evolution of vertebrates in islands or mainland habitats –and ~150 years after the publication of "On the origin of species..."– we are still trying to understand the many processes that originate species diversity. The twigs and wigs of the Tree of Life. 
Picture
I am a Bolivian national. And, not too many people visit Bolivia. I hope you do one day. Crystal clear skies will surprise you. The picture above was taken in the Salar de Uyuni (Uyuni Salt flats) and it somehow embodies my country — pristine (mostly), vast and wild. So if you are lucky enough to go, you should not expect the standard hotel accommodations at the exit of every small town (you can go to Chile, Brazil or Argentina for that). Bolivia is rarely uneventful, but know that you'll be visiting the most authentic country in South America.
