Scientists said on Tuesday that they had discovered the world's first hybrid sharks in Australian waters , a potential sign the predators were adapting to cope with climate change . The mating of the local Australian black-tip shark with its global counterpart, the common black-tip, was an unprecedented discovery with implications for the entire shark world, said lead researcher Jess Morgan . "It's very surprising because no one's ever seen shark hybrids before, this is not a common occurrence by any stretch of the imagination," Morgan, from the University of Queensland , told AFP. "This is evolution in action." Colin Simpfendorfer , a partner in Morgan's research from James Cook University , said initial studies suggested the hybrid species was relatively robust, with a number of generations discovered across 57 specimens. The find was made during cataloguing work off Australia's east coast when Morgan said genetic testing
