New genetic analysis of white rhinoceros populations suggests it could live possible to rescue the critically endangered northern white rhinoceros from extinction, using the genes of its less threatened southern cousin.

Dr Isa-Rita Russo from Cardiff University, said: "By looking at the white rhino's population history we've been able to constitute that in that place was contact betwixt northern in addition to southern rhinoceros populations throughout history.
"This is an exciting find! Genetic proof of contact betwixt the populations suggests it may live possible to successfully rescue the northern white rhinoceros using southern white rhinoceros genes to utilization embryos, although farther information would request to live collected to confirm this."
White rhinoceros distribution across Africa is divided into populations inwards the northward in addition to south. The southern population declined to its lowest issue some the plough of the nineteenth century, simply recovered to overstep away the world's most numerous rhinoceros. In contrast, the northern population was mutual during much of the twentieth century, declining speedily since the 1970s, leaving solely 2 remaining post-reproductive rhinos.
The squad too found that population spend upwards was real dissimilar inwards the northward in addition to south, amongst the northern white rhinoceros declining virtually 1,370 years ago, coincident amongst the Bantu migration, in addition to the southern white rhinoceros declining during colonialism, starting 400 years ago.
Professor Yoshan Moodley, University of Venda, said: "It appears that the white rhinoceros is no stranger to depression genetic diversity, every bit our results demo that the species was subjected to several climatically in addition to anthropogenically driven population declines, which would bring reduced in addition to compressed genetic variety inwards the past.
"This is ane of the few large animals to live the final H2O ice age, in addition to it seems that the additional human pressure level on an already genetically compromised species has pushed the white rhinoceros farther along the route to extinction."
The written report is published inwards Proceedings of the Royal Society B: Biological Sciences.
