Social hierarchies resulting from the European colonization of the Americas stratified the population structure, leading to ancestry-related assortative mating and sex bias patterns that can be inferred from the genomes of the populations across the continent.

The prediction accuracies of polygenic scores in humans vary depending on the characteristics of the samples, as well as based on the study design, within a single ancestry group.

The link between height and cognitive assessment scores substantially weakened from 1957 to 2018.

Admixture dynamics have recently changed over time in Mexican Americans resulting in an impact on the genetic architecture of phenotypic variation.

It is unclear how much a child's BMI at age 8 affects their depressive and ADHD symptoms after family-level factors are accounted for, but a substantial impact on anxiety symptoms is unlikely.

In the marine midge Clunio marinus, sympatric ecological population divergence with gene flow is based on at least four genetic loci, which partially overlap with large chromosomal inversions.

The adaptive value of social behaviour exhibited in adult life varies with conditions experienced in early life, and poorer conditions may promote conflict over cooperation.

Adopted individuals in large-scale population based cohorts can be leveraged to partition maternal genetic effects into prenatal and postnatal components, helping elucidate the underlying mechanisms behind these associations, and for diseases, yielding important information regarding the optimal timing of interventions.

Genetic data from siblings provides strong evidence that taller height increases the risk of cancers but lowers the risk of coronary disease.

Many of the effects of intelligence on health and social outcomes later in life are mediated via education.
