Fishy Accusation Rendered Mute

摘要

(Reuters) - A fish that made a stir last year with an apparent mutation that critics of Canada's oilsands industry blamed on pollution was not mutated at all, a scientist said Monday.The goldeye, which children pulled last summer from Lake Athabasca, downstream from northern Alberta's oilsands developments, had a stiffened tongue, not two jaws, as was first suspected, said Joe Nelson, professor emeritus of biological sciences at the University of Alberta.
