The concept of a universal human nature, based on a species-typical collection of complex psychological adaptations, is defended as valid, despite the existence of substantial genetic variation that makes each human genetically and biochemically unique. These apparently contradictory facts can be reconciled by considering that (a) complex adaptations necessarily require many genes to regulate their development, and (b) sexual recombination makes it improbable that all the necessary genes for a… Expand

Topics from this paper

Adaptive genetic variation and human evolutionary psychology.
TLDR
A model is presented that shows how a combination of genetic polymorphism and phenotypic plasticity might be favored by natural selection in humans and other species. Expand
Human nature or human natures
TLDR
There is no conceptual barrier to the existence of EEAs in post-Pleistocene times, and such a paradigm could shed light on such research topics as the visual word form area, reproductive strategy, predisposition to violence among young men, and personality traits. Expand
Evolutionary Perspectives on Personality and Individual Differences
Individual differences are essential to the process of evolution by natural selection. Natural selection is the only known process capable of creating and maintaining adaptations. The properties ofExpand
Evolution of Brain Structures and Adaptive Behaviors in Humans and Other Animals: Role of Polymorphic Genetic Variations
TLDR
The genetically polymorphic model reconciles fundamental assumptions of evolutionary psychology with basic principles of evolutionary biology, behavioral genetics, and neuroscience and predicts that humans and other animal species have evolved many nonuniversal complex behaviors that differ genetically between males and females, as well as within males and within females. Expand
Human Biological and Psychological Diversity
Many evolutionary psychologists have asserted that there is a panhuman nature, a species typical psychological structure that is invariant across human populations. Although many social scientistsExpand
Genes and Cultures
A central theme of the flood of literature in recent years in evolutionary psychology and behavioral genetics is that much or even most human behavior has been programmed into the human genome byExpand
Adaptation: “A Critique of Some Current Evolutionary Thought”
  • H. Cronin

In his classic Adaptation and Natural Selection: A Critique of Some Current Evolutionary Thought (1966), George Williams showed definitively that our understanding of adaptation, a central concept ofExpand
Evolutionary psychology and genetic variation: non-adaptive, fitness-related and adaptive.
TLDR
Direct and indirect evidence on humans support the notion that some phenotypic variance is fitness related, and while adaptive alternatives are unlikely to be found at a level of highly complex design, frequency dependent selection can maintain variation at finer, quantitative levels. Expand
Genes and Cultures
A central theme of the flood of literature in recent years in evolutionary psychology and behavioral genetics is that much or even most human behavior has been programmed into the human genome byExpand
Adaption Versus Phylogeny: The Role of Animal Psychology in The Study of Human Behavior
Advocates of Darwinian approaches to the study of behavior are divided over what an evolutionary perspective is thought to entail. Some take "evolution-minded- ness" to mean "phylogeny-mindedness,"Expand

The evidence for pervasive frequency-dependent selection is now very strong and can explain the maintenance not only of conventional polymorphism but also of continuous variation in both molecular and morphological characters. Expand

It is argued that, although substantial problems remain, evolutionary biology can provide one means for identifying relations between individual differences and species-typical characteristics and some of the difficulties of this endeavor are identified. Expand

TLDR
George Williams's "Adaptation and Natural Selection", now a classic of science literature, is a thorough and convincing essay in defense of Darwinism; its suggestions for developing effective principles for dealing with the evolution debate and its relevance to many fields outside biology ensure the timelessness of this critical work.

Short-term selection for recombination among mutually antagonistic species
TLDR
In this paper, it is shown how the mutual antagonism of two species can lead to a cyclical game in which high-recombination alleles can have a large short-term selective advantage in a fully defined genetic model. Expand

TLDR
Sexual generated progeny of Anthoxanthum odoratum have reproductive rates, summed over two years, that are 1.43 times those of their asexually generated siblings. Expand
