I may be easily entertained but nothing delights me more than a well-designed research project. It is even better when the responsible scientist is well-spoken and can explain they whys and hows of the experiment. All of those pieces came together today when I listened to the CBC program Quirks and Quarks. The 'whys' concern the development of cooking in human evolution. The 'hows' involve determining whether chimpanzees can comprehend the fact of transforming food through cooking.
