A Genome-Wide Association Study Identifies Five Loci Influencing Facial Morphology in Europeans – “Our results also suggest that the high heritability of facial phenotypes seems to be explained by a large number of DNA variants with relatively small individual effect size, a phenomenon well known for other complex human traits, such as adult body height.”
The Genetic Correlation between Height and IQ: Shared Genes or Assortative Mating? – “In this study, we used a large (total N = 7,905), genetically informative dataset to understand why two potentially sexually selected traits in humans—height and IQ—are correlated. We found that both shared genes and assortative mating were about equally important in causing the relationship between these two traits.”

When linearity was assumed, there is a substantial positive correlation between most religiosity measures and fear of death…. [F]emales were more religious and feared death more than did males, and Muslims expressed considerably greater fear than did members of any other major religion.” – @mein naturwissenschaftsblog.
