The object of study of the research group are the mechanisms that regulate the metamorphosis of insects , and how these mechanisms have evolved from ancestral species, with a gradual metamorphosis (like in cockroaches or locusts), to the most modified species, with a discontinuous metamorphosis (like in butterflies or flies). Therefore, the questions that the research group on the Evolution of insect metamorphosis seek to answer are: How did metamorphosis develop in insects? What endocrine and molecular mechanisms led to the evolutionary transition from gradual to discontinuous metamorphosis?
