> genetic predetermination == ancestry You're the best kind of correct: technically correct. Different ethnicity+gender combinations do in fact produce differing relative-frequencies of IQs (and EQs, and VO2Max'es, etc.). However. These are only averages. Statistics. Scalar summaries of large groups. Human genetic diversity being what it is, you cannot confidently tell what someone's intelligence or strength is, based on solely their ethnicity. Attempting to do so, is what racism is. Furthermore, I am reasonably confident that there is no ethnicity in the entire human species which is incapable of producing, under the correct environment, an Einstein, a Gandhi and a Ryan Kipchoge. However, if you were to examine an individual's specific genetics, and if we knew enough about the details of how every specific gene interacts to produce the phenomemon of the human body ... then you could indeed determine the maximum, predestined mental and physical potential of that individual. Not their children, not their parents, not their brothers, not their close cousins. Meiosis and mutation are (one of the few aspects of biology that I actually think to be) beautiful.
