EXCERPT: When it comes to getting out of a tricky situation, we humans have an evolutionary edge over other primates. Take, as a dramatic example, the Apollo 13 voyage in which engineers, against all odds, improvised a chemical filter on a lunar module to prevent carbon dioxide buildup from killing the crew.
UC Berkeley scientists have found mounting brain evidence that helps explain how humans have excelled at “relational reasoning,” a cognitive skill in which we discern patterns and relationships to make sense of seemingly unrelated information, such as solving problems in unfamiliar circumstances.
Their findings, reported in the Dec. 3 issue of the journal Neuron, suggest that subtle shifts in the frontal and parietal lobes of the brain are linked to superior cognition. Among other things, the frontoparietal network plays a key role in analysis, memory retrieval, abstract thinking and problem-solving, and has the fluidity to adapt according to the task at hand.
“This research has led us to take seriously the possibility that tweaks to this network over an evolutionary timescale could help to explain differences in the way that humans and other primates solve problems,” said UC Berkeley neuroscientist Silvia Bunge, the study’s principal investigator.
“It’s not just that we humans have language at our disposal. We also have the capacity to compare and integrate several pieces of information in a way that other primates don’t,” she added....
