Is it possible that what guides us in love is not just in our heart but in our genes? That's what researchers are studying at the Atlanta Center for Behavioral Neuroscience. They've found a difference in mating when it comes to prairie rats and meadow rats. They also found a gene in the prairie rat's brain that makes it monogamous, but that gene is missing in the meadow rat so it mates with whatever rat is around.
Before you make your own diagnosis about someone you know Dr. Larry Young says humans are made with that same monogamy gene.
"These receptors are concentrated in the brain's reward areas. These same areas that are involved in addiction," said Dr. Larry Young, of the Atlanta Center for Behavioral Neuroscience.
Doctor Young cautions that before we blame our genes for bad behavior we need to remember that humans are made with the capacity to think and make moral judgements.
