Suarez reports a greater magnitude of fluctuating dental asymmetry for Neandertal sample when compared with a sample of modern Ohio whites. He postulates that this greater antimeric variance could be due to a greater degree of inbreeding in the Neandertal populations. In the present investigation, the magnitude of fluctuating dental asymmetry is evaluated for Eskimo and Pueblo populations. These populations were found to exhibit dental variance of equal magnitude to that of the Neandertal population. As these populations are not highly inbred, a stress related mechanism is suggested to explain these observations and the inbreeding hypothesis is rejected. The implications of this mechanism to Brace's Probable Mutation Effect are discussed.
苏亚雷斯报告称，与现代俄亥俄白人样本相比，尼安德特人样本的牙齿波动不对称程度更大。他推测，这种更大的对侧差异可能是由于尼安德特人群体中近亲繁殖程度更高。在本研究中，对爱斯基摩人和普韦布洛人群体的牙齿波动不对称程度进行了评估。发现这些人群体的牙齿差异程度与尼安德特人群体相同。由于这些人群并非高度近亲繁殖，因此提出了一种与压力相关的机制来解释这些观察结果，并拒绝了近亲繁殖假说。讨论了这种机制对布雷斯可能的突变效应的影响。
