I found [Séralini et al.’s] paper understandable and clear. The main conclusions are well supported by the data and the limitations of the study appear clearly. Of course, this work raises numerous questions, but this is the case with any pioneering research. The only way to answer these questions is by further experimentation, either replicating or improving the experimental design of Séralini et al.
