15 generations of untrained jocks, couch potatoes show big physiological adaptations
So, you don't like to exercise? Maybe you could blame it on your great-great-grandparents. Similarly, if you're a practiced and proud couch potato who suddenly woke up to the fact that you're a "natural" athlete, the credit could also belong to your genes. Exercise research traditionally has focused on the effects of training, rather than underlying genetic mechanisms. But physiologists wo...Chimpanzees can transmit cultural behavior to multiple 'generations'
Transferring knowledge through a chain of generations is a behavior not exclusive to humans, according to new findings by researchers at the Yerkes National Primate Research Center of Emory University and the University of St. Andrews, Scotland. For the first time, researchers have shown chimpanzees exhibit generational learning behavior similar to that in humans. Unlike previous findings that in...Low levels of neurotransmitter serotonin may perpetuate child abuse across generations
Infant abuse may be perpetuated between generations by changes in the brain induced by early experience, research shows at the University of Chicago shows. A research team found that when baby rhesus monkeys endured high rates of maternal rejection and mild abuse in their first month of life, their brains often produced less serotonin, a chemical that transmits impulses in the brain. Low...
