Running, a seemingly simple physical activity, has played a surprisingly profound role in human evolution—not just in shaping our bodies but also in fuelling the growth and complexity of our brains.
According to the leading sex website in Australia, Erobella, many people take this everyday action for granted without realising that running has been a crucial factor in the development of cognitive abilities that distinguish humans from other species.
How Running Helps
Millions of years ago, early humans faced the challenge of securing food in a hot, dry African climate. Unlike other predators that relied on speed and strength, our ancestors adopted a unique strategy known as persistence hunting. This involved tracking and chasing prey over long distances in the midday heat until the animal was too exhausted to escape. To succeed at this, early humans needed more than endurance—they needed coordination, memory, and advanced problem-solving skills.
This is where the brain comes in. Running long distances demands more than physical stamina; it also requires awareness of one’s surroundings, the ability to track subtle cues like footprints or broken twigs, and a sharp sense of direction. These skills depend on the brain’s ability to process complex information quickly and efficiently. Scientists believe that the demands of persistence hunting encouraged the development of enhanced cognitive functions, including spatial reasoning and planning.
Moreover, running influences the brain on a chemical level. Modern studies have shown that aerobic exercise like running increases levels of brain-derived neurotrophic factor (BDNF), a protein that supports the growth of new neurons and strengthens connections between brain cells. This not only improves memory and learning but also helps protect against cognitive decline as we age. It’s likely that even our ancient ancestors benefited from these effects, which may have contributed to their survival and adaptability.
Social Interaction
Social interaction also played a role. Early humans often hunted in groups, which required communication, cooperation, and the ability to understand the thoughts and intentions of others—what psychologists call theory of mind. These social and cognitive challenges further spurred the expansion of brain regions involved in language, empathy, and group coordination.
Interestingly, the physical structure of the human body evolved in ways that support long-distance running. We developed longer legs, shorter toes, spring-like tendons, and a unique ability to sweat and cool down, all of which made running more efficient. As our bodies adapted, so did our brains, in a beautifully interconnected process.
Runner’s High
In today’s world, we no longer need to run for our meals, but the evolutionary link between running and brain development remains relevant. Regular running can boost mental clarity, reduce stress, and even improve mood by releasing endorphins—often referred to as a “runner’s high”.
In essence, running helped shape not just the way we move but the way we think. Our ancestors’ ability to run transformed them from prey into persistent hunters, from simple tool-users into strategic thinkers. The mental edge we enjoy today owes a surprising debt to this most basic of human movements.
