BIOLOGY OF NATURAL AND FORCED MIGRATIONS | BIONATURE

Man has evolved from caves to occupying every feasible biological niche, including forests, mountains, river banks, and sea coastlines, over the last two thousand years. Architectural anthropology and blood genetics are likely to blame for man's adaptability. By switching on and off regulatory genes over each individual's lifetime, human haemoglobin chains provide regulatory flexibility for reproductive biology. Our haemoglobin chain design provides physiological adaptability that is changeable and versatile (more so on account of HbF proportions in the adult blood). Practically, the evolution of blood physiology has automatically ensured physiological resilience in all vertebrates, and the fraction of gamma chains in amphibians continues to respond to adaptive stressors. This report, based on ongoing research, underlines the importance of conducting comprehensive studies to better understand the effects of abrupt and natural migrations on altering patterns of foetal haemoglobin and their adaptive implications in adulthood. Shifting populations under duress may be causing more socio-biological issues.
