In simplest terms, natural selection did not organize our mating strategies, nor our psychosexual natures, with modern relationship values in mind—and the resulting tension can cause a great deal of trouble. As Symons (1985) puts it, “in analyzing the psychological underpinning of marriage [we...
We expect that natural selection should result in behavioural rules which perform well; however, animals (including humans) sometimes make bad decisions. Researchers account for these with a variety of explanations; we concentrate on two of them. One explanation is that the outcome is a side effec...
ExpressionTrees are used to generate C# code and are the subject of selection and reproduction. ExpressionTree has a single constructor, shown in Figure 7. This builds a random tree from the set of Functions and an ArrayList of terminals. MaxDepth controls how deep the tree can grow—when ...

Schematic overview of belief updates for active inference under discrete Markovian models. The left panel lists the belief updating equations, associating various updates with action, perception, policy selection, precision and learning. The left panel assigns the variables (sufficient statistics or expecta...
Fisher's fundamental theorem of natural selection shows that the part of the rate of change of mean fitness that is due to natural selection equals the additive genetic variance in fitness. Fisher embedded this result in a model of total fitness, adding terms for deterioration of the enviro...
De novo variants are genetically different from inherited variants, and are more damaging because mutation processes in de novo variants are happening between generations without undergoing purifying selection [84]. De novo, truncating variants correlate with severe disease in both female and male ...
The neurodegenerative condition known as Parkinson’s disease (PD) is brought on by the depletion of dopaminergic neurons in the basal ganglia, which is the brain region that controls body movement. PD occurs due to many factors, from which one of the acknowledged effects of oxidative stress is...
