IBE (CSIC-UPF): Going underground was not "The End" but "To be continued"

IBE (CSIC-UPF): Going underground was not "The End" but "To be continued"


News from IBE (CSIC-UPF)


Subterranean species are usually strongly modified both in their morphology and biology. They are usually though as evolutionary dead ends, confined by limited dispersal and strict ecological requirements. In a recent study, researchers from the IBE found that in a Pyrenean subterranean beetle lineage an extreme modification, the progressive reduction of the number of larval instars leading to a non-feeding, inactive larvae that does not moult, evolved only once during the lower Miocene.

The results imply that a highly modified subterranean lineage can expand its geographic range and diversify over long evolutionary periods. The study is a joint work between the Ignacio Ribera Lab and collaborators of the Museu de Ciències Naturals de Barcelona.
