In the context of pre-events held in June 2021 for the European Researchers Night, Sara Gamboa presented the talk “Cómo conseguir un mamut: ADN fósil” (How to obtain a mammoth: fossil DNA) to over 200 students from high schools in Vigo and Mos. In this talks, students learned basic genetics concepts and how this discipline could be used to study species from the past or even to achieve the de-extinction of some of them.
