Resumen de On the edge
Pain talks about the rescue of the Chatham Island black robin, which has offered conservationists hope: no matter how bad things look, it is possible to bring a species back from the very brink of extinction. Now, however, Massaro and her colleagues at the University of Canterbury in New Zealand have discovered that the legendary team of conservationists who helped Old Blue and her offspring unwittingly nudged the black robin onto an evolutionary path that almost led to disaster. So the great success story is also a cautionary tale, with important lessons for anyone thinking of stepping into save species.
