Discovery of genetic differences, using DNA analysis, could boost efforts to save declining populations
Researchers have discovered there are not just one but four distinct species of giraffe, overturning two centuries of accepted wisdom in a finding that could boost efforts to save the last dwindling populations.
Analysis of DNA evidence from all of the currently recognised nine sub-species found that there is not just one species of giraffe but enough genetic differences to recognise four distinct species. Experts said the differences are as large as those between brown bears and polar bears.
Giraffe have suffered a decline in number from around 150,000 across Africa three decades ago to 100,000 today, as their habitat has been turned over to agriculture. But as a single species the giraffe is currently listed as of least concern on the red list of endangered species, leaving the tallest living animals a relatively low conservation focus compared to rhino and elephant.
“People need to really figure out that giraffes are in danger. There are only 100,000 giraffes left in Africa. We’ll be working closely with governments and big NGOs to put giraffes on the radar,” said Dr Julian Fennessy, lead author of the new study which saw genetic testing in Germany on 190 giraffe.
The four recommended new species are the southern giraffe, with two subspecies, the Angolan giraffe and South African giraffe; the Masai giraffe; the reticulated giraffe; and the northern giraffe including the Kordofan giraffe and west African giraffe as subspecies.
