Your article gives a simplistic and generally inaccurate account of the relationship between Fst [also called Wright’s F statistic] and race/subspecies/species. Fst reflects the relative amount of total genetic variation between populations. While there is bound to be a correlation between Fst and species status, Fst is not normally used to define species. An Fst […]

Letters from the June 4, 2005, issue of Science News
Stem winder “Full Stem Ahead” (SN: 4/2/05, p. 218) showed several reasons why stem cell research is a good thing: Stem cells from embryos might cure cancer, Parkinson’s disease, Alzheimer’s disease, diabetes, and many other diseases. But the article should have included the fact that stem cells may help with transplanting organs. Stem cells may […]
