“…But disgust does not appear to decrease in response to toxin presence. For instance, Kauffman et al [35] found that hungry participants were less likely to consume quinine-containing milkshakes, and Stevenson et al [36] found that thirsty participants were less likely to drink quinine-containing liquids. When the body is in a depleted nutritional state, the consumption system appears to weight cues to toxin presence even more negatively, which is what bitter-tasting quinine is perceived to be.…”

Disgust is an emotion intimately linked to pathogen avoidance. Building on prior work, we suggest disgust is an output of programmes that evolved to address three separate adaptive problems: what to eat, what to touch and with whom to have sex. We briefly discuss the architecture of these programmes, specifying their perceptual inputs and the contextual factors that enable them to generate adaptive and flexible behaviour. We propose that our sense of disgust is the result of these programmes and occurs when information-processing circuitries assess low expected values of consumption, low expected values of contact or low expected sexual values. This conception of disgust differs from prior models in that it dissects pathogen-related selection pressures into adaptive problems related to consumption and contact rather than assuming just one pathogen disgust system, and it excludes moral disgust from the domain of disgust proper. Instead, we illustrate how low expected values of consumption and contact as well as low expected sexual values can be used by our moral psychology to provide multiple causal links between disgust and morality.This article is part of the Theo Murphy meeting issue 'Evolution of pathogen and parasite avoidance behaviours'.

“…The hydrochemistry perhaps shifted to lower sulphate content in the uppermost part of the section. 4.5 Early hominin adaption to highly mineralized water resources at the spring of Nadaouiyeh Aïn Askar Drinking water quality in terms of TDS content is a heavily discussed issue, because salt content has influence on human behavior and can be a health risk or even a lethal factor (Gleibermann, 1973;Meadow, 1993;Stevenson et al, 2010). Natural selection for electrolyte conservation has also been an important issue throughout human evolutionary history (Jackson, 1991).…”
