One example that caught my attention is the case of Darwin's finches on Daphne Major Island. In 1981, a finch from the species Geospiza conirostris arrived from another island and mated with a local G. fortis female. What's fascinating is that their descendants formed their own group that now only mates within that group. Scientists ended up calling this new lineage \"Big Bird? There was geographic isolation first since the new finch came from a different island. Over time, they became reproductively isolated too because their song and beak shape were different from the original birds. What surprised me is that this all happened in just seven generations. So this was a fast example of speciation
