Ancestors Can Genetically Pass On Fears

Here’s one for the nature versus nurture argument. Apparently a study recently published in Nature Neuroscience concludes that certain fears can be passed on genetically. For their experiment a group of rats were taught to fear a particular smell. Scientists then noted that the fear of that smell was passed on to their offspring, thus concluding that fear can indeed genetically alter the brain and thought process. Crazy. Considering how many ideas, fears and psychological blips can exist within the human psyche, folks can definitely rule in ancestral influence.
