DNA methylation in peripheral tissues and left-handedness [PDF]

open access: yesScientific Reports, 2022
Handedness has low heritability and epigenetic mechanisms have been proposed as an etiological mechanism. To examine this hypothesis, we performed an epigenome-wide association study of left-handedness.

Bipedalism and brain expansion explain human handedness. [PDF]

open access: yesPLoS Biology
Humans exhibit a striking and near-universal population-level right-hand preference, an evolutionary singularity unmatched among primates. Despite its pervasiveness, the origins of this lateralization remain poorly understood.

Heterochely and handedness in the orange mud crab Scylla olivacea: implication for future culture practice optimisation [PDF]

open access: yesPeerJ, 2023
Asymmetric body traits in bilateral organisms are common and serve a range of different functions. In crustaceans, specifically among brachyuran crabs, heterochely and handedness in some species are known to aid in behavioural responses such as food ...

Perinatal factors and umbilical cord characteristics in determining handedness: results from the Belgian East Flanders prospective twin survey [PDF]

open access: yes, 2012
Aims: The objective was to determine if perinatal factors and umbilical cord characteristics showed any association with left-handedness in a set of twin subjects.

PCSK6 VNTR Polymorphism Is Associated with Degree of Handedness but Not Direction of Handedness. [PDF]

open access: yesPLoS ONE, 2013
Although the left and right human cerebral hemispheres differ both functionally and anatomically, the mechanisms that underlie the establishment of these hemispheric specializations, as well as their physiological and behavioral implications, remain ...

The relation between handedness indices and reproductive success in a non-industrial society. [PDF]

open access: yesPLoS ONE, 2013
The evolution of handedness in human populations has intrigued scientists for decades. However, whether handedness really affects Darwinian fitness is unclear and not yet studied in a non-industrial society where selection pressures on health and ...

Is Psychopathy a Mental Disorder or an Adaptation? Evidence From a Meta-Analysis of the Association Between Psychopathy and Handedness

open access: yesEvolutionary Psychology, 2021
Psychopathy has historically been conceptualized as a mental disorder, but there is growing evidence that it may instead be an alternative, adaptive life history strategy designed by natural selection.

Genome‐wide association and replication studies for handedness in a Korean community‐based cohort

open access: yesBrain and Behavior, 2023
Introduction Handedness is a conspicuous characteristic in human behavior, with a worldwide proportion of approximately 90% of people preferring to use the right hand for many tasks.

Handedness in twins: meta-analyses

open access: yesBMC Psychology, 2022
Background In the general population, 10.6% of people favor their left hand over the right for motor tasks. Previous research suggests higher prevalence of atypical (left-, mixed-, or non-right-) handedness in (i) twins compared to singletons, and in (ii)
