Behave: The Biology of Humans at Our Best and Worst

Product Information

Shortform note: Many researchers today—including Sapolsky— no longer recognize a clear divide between our genetics and our environments when it comes to behavior. Rather, as we’ll see in this guide, just about everything is the result of interactions between nature and nurture. In other words, there’s no such thing as a gene that forces us to act a certain way. At most, one could say that genes predispose us to certain behaviors.) The Structure of the Brain Vaughan, Christopher (November 2001). "Going Wild A biologist gets in touch with his inner primate". Stanford Magazine . Retrieved March 15, 2019. Author: Robert Morris Sapolsky (born April 6, 1957) is an American neuroendocrinologist and author. He is currently a professor of biology, and professor of neurology and neurological sciences and, by courtesy, neurosurgery, at Stanford University. He has appeared on the Joe Rogan Experience. Josh Greens is tragedy of the commons versus tragedy of the common sense of morality were acting morally towards an ass is automatic while doing so for a them text work. Steve Pinker failed to take things one logical step further in his book Enlightenment Now. He didn’t correct for different durations of events. He compares the half-dozen years of World War 2 with 12 centuries of the middle age slave trade! When correcting for duration as well as total world population the top 10 most violent wars now include World War 2, World War 1, the Russian Civil War now and another 20th Century event that didn’t even make Pinker’s original list, the Rwandan genocide.

It remains debatable, though, whether strict determinism is compatible with Sapolsky’s final message of hope for humanity, as he tells inspiring stories about moral heroism in history – the helicopter officer who stopped the My Lai massacre, the Christmas Day football match during the first world war. Sapolsky is on the side of Steven Pinker’s argument, in The Better Angels of Our Nature, that humanity is overall getting less violent and nasty, and points to some lessons from the “social plasticity” demonstrated in troops of baboons, one of Sapolsky’s own specialities. He thus sets himself against conservative pessimism about brutish human nature. “Anyone who says that our worst behaviours are inevitable knows too little about primates, including us.” This is very interesting. So if the amygdala is where aggression is generated, it seems like the frontal cortex is where aggressive impulses and emotions are inhibited. In fact, the most common therapy for both anger and anxiety issues is cognitive behavioural therapy, which teaches people new ways of interpreting and processing life situations. It seems to be using the rational reasoning of the frontal cortex to retrain the amygdala.a b Sapolsky, RM (2004). "The frontal cortex and the criminal justice system".

In rodents and baboons, the lower an individual is on the social hierarchy, the higher their resting levels of glucocorticoids are. This translates to all kinds of negative health effects like we just mentioned. As baboons rise in the hierarchy, they tend to have lower levels of stress hormones, with one big exception. The alpha male at the top has very high stress levels, as high as the lowest-ranking baboon. Why? Well, probably because he has to spend much of his time fighting and defending his sexual partnerships, which must be very stressful.In 1944, near the end of World War 2, the Netherlands was being occupied by Nazi forces, which caused the Dutch people to endure a terrible famine called the Dutch Hunger Winter. More than 20,000 people died, but the most surprising result is that decades later effects of the famine still echo inside Dutch people’s genes. Women pregnant during the famine gave birth to babies that later in life were more likely to have obesity, diabetes, schizophrenia. They also die more easily or at a higher rate than other people. This event really illustrated for scientists the powerful influence of a person’s environment even before birth. Now, what about after birth? So inside the brain, one of the neurotransmitters our neurons use to talk to each other is dopamine. There are 4 pathways in our brains that make us what scientists call the dopamine reward system. It’s what makes things feel really good and it’s why we do most actions in the first place. For example, eating food when hungry releases dopamine in the brains of most species, and so does having sex. (In fact, humans only need to think about sex to trigger dopamine release.)
