Research into the brain’s "connectome" shows that everyone’s neural wiring is unique. For example, the high levels of vigilance seen in people with anxiety are not necessarily "broken" circuits; rather, they are highly sensitive systems that, in a different ancestral context, would have been vital for survival. By looking at brain scans and neurochemical patterns, scientists are finding that "normal" is a statistical average rather than a biological standard. The Genetic Mosaic

The traditional view of mental health has long relied on a binary system: you are either "normal" or you are "disordered." This clinical divide suggests a clear boundary between the healthy mind and the pathological one. However, as our understanding of genetics, neuroscience, and evolutionary biology deepens, this rigid line is beginning to blur. We are entering an era where biology reveals that what we once labeled as "abnormal" may actually be a natural variation of the human experience. The Spectrum of the Human Brain The Genetic Mosaic The Other Side of Normal:
Anxiety: A "hyper-reactive" amygdala would keep a tribe safe from predators. The Spectrum of the Human Brain Anxiety: A
The answer may lie in "mismatch theory." Traits that are considered problematic in a modern, sedentary, 9-to-5 office environment might have been highly adaptive in a hunter-gatherer society.
This perspective fuels the Neurodiversity Movement, which advocates for the recognition that neurological differences are a natural part of human diversity. From a medical standpoint, this leads to personalized medicine—using a person's specific genetic profile and brain chemistry to tailor interventions that work with their biology rather than against it. Conclusion
ADHD: Hyper-focus and high energy would have been assets for a scout or hunter.
