Marcel Just, a respected neuroscientist, pointed to the Smithsonian Institute's 2013 announcement regarding the olinguito, a recently identified carnivore species that primarily eats lives and fruits by itself in the treetops of rainforests, for example of the sort of new concept that folks learn. 'Thousands of people read the given information about the olinguito and in doing this permanently changed their own brains,' said Just, the D.O. Hebb University Professor of Cognitive Neuroscience in CMU's Dietrich College of Social and Humanities Sciences..

Can a flavor for poison travel speciation? The endless struggle for survival in nature inevitably boils right down to finding food and eluding predators. To avoid the latter, many plants produce chemical weapons to discourage predators. A sound strategy general, but the guidelines of co-evolutionary war suggest that an herbivore will evolve resistance to the toxic defenses of plants. The fruit fly Drosophila sechellia, for example, includes a penchant for the fruit of a Polynesian shrub known as Tahitian Noni that smells so foul it’s nicknamed ‘vomit fruit.’ Additional Drosophila species deal with the rank smell, which arises from the poisons hexanoic acid and octanoic acid, as a warning sign to remain away.
