Wright himself believed that values >0.25 represent very great genetic variation and that an FST of 0.150.25 represented great variation. However, about 5% of human variation occurs between populations within continents, therefore FST values between continental groups of humans (or races) of as low as 0.1 (or possibly lower) have been found in some studies, suggesting more moderate levels of genetic variation. Graves (1996) has countered that FST should not be used as a marker of subspecies status, as the statistic is used to measure the degree of differentiation between populations, although see also Wright (1978).

FST is used to measure the degree of differentiation between what?
Answer: populations

Today, Estonian society encourages liberty and liberalism, with popular commitment to the ideals of the limited government, discouraging centralised power and corruption. The Protestant work ethic remains a significant cultural staple, and free education is a highly prized institution. Like the mainstream culture in the other Nordic countries, Estonian culture can be seen to build upon the ascetic environmental realities and traditional livelihoods, a heritage of comparatively widespread egalitarianism out of practical reasons (see: Everyman's right and universal suffrage), and the ideals of closeness to nature and self-sufficiency (see: summer cottage).

What ideal does Estonia hold towards the environment?
Answer:
closeness to nature
