The story of humanity’s interaction with the northern white rhino is one of the conservation movement’s grimmest tales of recent years. “In the 60s there were 2,500 northern whites left in central Africa,” said Paul De Ornellas of the Zoological Society of London. “Poaching brought that down to 30 by the end of the 20th century, and now to the last two.”
Last week the species’ last male, Sudan, had to be put down because of ill health, leaving only two ageing females on the planet as representatives of a creature that once roamed in its tens of thousands across Africa. It is a sad history which, most of the world assumes, is nearing its end.
But human ingenuity could yet save a species that has been brought to the brink of extinction. The plan, which involves in vitro fertilisation (IVF), stem cell science and gene editing, could also pave the way to rescue other animals at risk, such as the Sumatran and Javan rhinos.
