Adaptive Radiation Constrained By Niche Availability

Understanding why there are so many species is an essential question in biology that continues to generate considerable curiosity and drive evolutionary research. Moreover, people seek to understand how species that are closely related can reside in very different niches and co-occur in areas. Darwin observed such an adaptive radiation with finches in the Galapagos, where the species of birds differ in the size and shape of their beaks, allowing … Continue reading
