By analyzing genomic data we can detect and use the footprints that adaptive (positive) natural selection leaves in our genome to identify human adaptations at different timescales, as well as the resulting phenotypical traits that in current populations define us as humans. Although genomics has ...
conscientiousness, extraversion, agreeableness, and neuroticism—can influence how individuals perceive and react to situations. Lucas and Fujita’s research (2000) on personality and subjective well-being suggests that traits like neuroticism and extraversion are strongly correlated with emotional reactions a...
are limited by our use of exclusively European data and the use of genome-wide association study data, which identify associations between genetic variants and phenotypes that may not be causal. In sum, we provide an overview of signals of selection on human polygenic traits and their ...
Given the large benefits produced by altruistic cooperation, it safe to assume that throughout human evolutionary history groups of altruistic cooperators would have thrived at the expense of groups of non-altruists. However, any explanation that invokes the (natural) selection of traits that ...
Differences in psychologists’ cognitive traits are associated with scientific divides Scientific disagreements are not just a matter of using different methods or having conflicting data. Sulik et al. surveyed psychological scientists and found that disagreements are also associated with differences in resea...
(1918)groundbreaking paper formed the basis for this development, specifically the recognition that phenotypic traits are polygenic, and that their inheritance does not follow a simple Mendelian model. While this advancement in the field of genetics provided a more sophisticated, more quantitative ...
The process of gait feature extraction (visual traits) is followed by segmenting and identification of human body parts based on thekinematic jointpoints. The stick figure (skeletonization) is constructed by connecting the segmented body parts and fuses the visual and skeletal traits. Afterward, spat...
Moreover, (intercept − 1)/(mean(χ2) − 1) was less than 0.12, further supporting the conclusion that HASV traits were influenced more by polygenicity than population structure (Additional file 1: Table S3). Observed scale heritability (h2) was estimated using the slope of L...
Conclusions Findings are discussed with regards to the importance of considering the interplay between obligate and facultative traits, particularly when opposing directions might occur due to evolutionarily novel preferences associated with intelligence, as well as in the context of evolutionary mismatch in...
10f). This suggests that LTi-like ILC3 subsets are expanded during the development of gut-associated lymphoid tissues, but not during the development of mLN. Single-molecule fluorescence in situ hybridization (smFISH) staining identified all three LTi-like subtypes (Extended Data Fig. 10g) and ...
