DNA study says there may be 11 kiwi species, ancestors driven apart by glaciers Posted Image Kiwi are weird. The bumbling flightless birds have long snouts with nostrils at the tip, they're nocturnal, and they smell a bit like mushrooms. Now, a groundbreaking DNA study of more than 200 birds suggests there are more species than the recognised five types and 16, or 17, distinct genetic forebears. ********** Research published in the the Proceedings of the National Academy of the Sciences by the University of Toronto on kiwi DNA says the modern birds - genetically speaking - evolved more recently than previously thought. A team led by University of Toronto Scarborough professor of biological sciences Jason Weir discovered that instead of the five known species, there are 11 types of birds alive now, with six species extinct. Scientists in Canada worked alongside the Department of Conservation. They have not concluded whether the 11 types represent separate species, or subspecies, but the lineages do represent separate populations. Source Link |
