Darwinists still do not have a full theory of human social organization. Relatedness is a key idea in evolutionary theory. Yet, despite some pioneering studies, few Darwinists have used formal measures of relatedness, and even fewer have us...

The ratio between the length of the 2nd and 4th digit (2D:4D) is sexually dimorphic, with mean male 2D:4D lower than mean female 2D:4D. It recently was suggested that 2D:4D is negatively correlated with prenatal testosterone and positively ...
