Substantial but Misunderstood Human Sexual Dimorphism Results Mainly From Sexual Selection on Males and Natural Selection on Females

It is argued that sex differences in adipose arise mainly from natural selection on women to accumulate neurodevelopmental resources, similar to those seen in primates where sexual selection, arising from aggressive male mating competition, has produced high levels of dimorphism.

Utility Rate Equations of Group Population Dynamics in Biological and Social Systems

It is found that, in a self-organized society, neither defectors nor regulators can overpass the maximal fractions of about each and, in agreement with the data for bee and ant colonies, the classification of societies by their distance from equilibrium is proposed.

A Generic Model of Dyadic Social Relationships

A model of dyadic social interactions is introduced and it is demonstrated that the relationships generated by this model aggregate into six exhaustive and disjoint categories, which infer that the four relational models form an exhaustive set of all possible dyadic relationships based on social coordination.

Dynamical Diagnosis and Solutions for Resilient Natural and Social Systems

An operation definition of resilience is proposed, seeing it as a measure of stress that is complementary to the risk measures, and the concept of "crisis flight simulators" is introduced to address the intrinsic human cognitive biases underlying the logic of failures and the illusion of control.

Modeling social interactions and their effects on individual decision making

In this thesis, we are interested in the influence of social environment on individual decision making. We develop models of social interactions and culture, with the aim to facilitate their

The Illusion of Success and the Nature of Reward

Many successful activities and outcomes benefit from strokes of luck. Moreover, humans are over-confident and tend to confuse luck for skill (Heads I win, it's skill; tails, I lose, it's chance).

The Fair Reward Problem: The Illusion of Success and How to Solve It

Humanity has been fascinated by the pursuit of fortune since time immemorial, and many successful outcomes benefit from strokes of luck. But success is subject to complexity, uncertainty, and change

Quantum Decision Theory in Simple Risky Choices

This article revisits the formalism of QDT along a concrete example and offers a practical guide to researchers who are interested in applying QDT to a dataset of binary lotteries in the domain of gains.

Significant hot hand effect in the game of cricket

An original temporal representation of performance streaks is introduced, which is suitable to be modelled as a self-exciting point process, and confirmed the presence of predictability and hot-hands across the individual performance and the absence of the same in team performance and game outcome.



Genetic evidence for unequal effective population sizes of human females and males.

A pattern that is remarkably consistent across all three populations is an approximately twofold deeper coalescence for mtDNA than for the NRY, which is most consistent with a higher female effective population size.

Genetic evidence for a higher female migration rate in humans

It is found that Y chromosome variants tend to be more localized geographically than those of mtDNA and the autosomes, and the reduction of variation within populations for Y chromosome single nucleotide polymorphisms (SNPs) is of such magnitude that differences in the effective population sizes of the sexes alone are insufficient to produce the observation.

Global patterns of human mitochondrial DNA and Y-chromosome structure are not influenced by higher migration rates of females versus males

A new strategy to assay Y-chromosome variation is introduced that identifies a high density of single-nucleotide polymorphisms, allows complete sequencing of all individuals rather than relying on predetermined markers and provides direct sequence comparisons with mtDNA.

New estimates of intergenerational time intervals for the calculation of age and origins of mutations.

Results showed that a mean value of 30 years is a better estimate of intergenerational intervals than 20 or 25 years, and specific values are proposed for mtDNA, autosomal, X- chromosomal, and Y-chromosomal loci.

Recent common ancestry of human Y chromosomes: evidence from DNA sequence data.

It is estimated that the spread of Y chromosomes out of Africa is much more recent than previously was thought, and the data indicate substantial population growth in the effective number of human Y chromosomes.

Sex-biased migration in humans: what should we expect from genetic data?

How the demographic shift associated with agriculture might affect genetic diversity over different spatial scales is shown and the prospects for studying sex-biased migration using the X-linked and autosomal markers are considered.

Y‐chromosome analysis confirms highly sex‐biased dispersal and suggests a low male effective population size in bonobos (Pan paniscus)

As predicted for a female‐dispersing species, much higher levels of differentiation among local bonobo populations based upon Y‐chromosomal than mtDNA genetic variation are found, suggesting a more stable demographic history in bonobos in comparison to humans.

Sex-Biased Evolutionary Forces Shape Genomic Patterns of Human Diversity

Factors leading to a lower male versus female effective population size must be considered as important demographic variables in efforts to construct models of human demographic history and for understanding the forces shaping patterns of human genomic variability.

Paternal investment and the human mating system

The Influence of Habitats on Mating Systems of North American Passerine Birds

Regardless of sex ratio, a polygynous mating is expected to be adaptive for the females as well as for the male, and marshes and prairies are more likely than forests to present the minimum requisite food supply and sufficiently great differences in available food between territories for selection to favor polygyny.
