Rodent Macroevolution in the context of Major Miocene Environmental Changes – RoMa

Submission summary

The Miocene is characterized by important tectonic activity that drove sea level changes and orogeny, in turn significantly altering
the climate. About 20 million years ago the contact between Afro-Arabia and Eurasia created a land-bridge that enabled faunal
exchanges between these two continents. The aim of this project is to unravel the evolutionary response of the most speciose group
of mammals, the rodents, in this unique context of overwhelming biotic and abiotic perturbations. Cutting-edge methodologies
together with a combination of morphological and molecular approaches with time-calibrated phylogenetic trees will allow inferring
the dynamics of speciation and extinction and the variation of diversity among lineages. Long-standing questions in evolutionary
biology will be addressed: why certain clades are highly diversified while others are not? Is this due to the appearance of key
innovations or related to extrinsic factors?
