191.1 The Mixed Paragraph Structure

Two known physiological adaptations to high-altitude environments involve hemoglobin. The first is an elevated hemoglobin concentration. The highest concentration known is in the Andean population. The Andean population exhibits a high heritability (\(H^2\) = 0.89) for this trait. The second adaptation is an elevated level of oxygen saturation in the blood. Strikingly, high oxygen saturation is associated with a doubling of neonate survival in Tibet compared to normal oxygen saturation levels.

So far we’ve seen how structure makes scientific writing cohesive, another important aspect is using transitions.
