Hematocrit levels in children at sea level and at high altitude: effect of adrenal androgens.

abstract：:Previous attempts to classify South American Indian tribes according to genetic characteristics have failed to yield a hierarchical system of relationships. This can be explained by the facts that (1) tribal populations did not evolve through sequential fissions but through frequent fusions of groups with diverse hist...
