Radiation Hormesis: an Evolutionary Expectation Invalidating the Linear No-threshold (lnt) Premise
Organisms survive best, or show high fitness, in the habitats in which they most commonly occur, a phenomenon referred to as hormesis in the literature of toxicology. Examples of hormesis accumulate rapidly in the literature. However, a lack of underlying models has led many to doubt its existence, especially for ionizing radiation. The evolutionary model developed here indicates that all poten...
متن کاملHormesis Is Biology, Not Religion
Should hormesis, as Thayer et al. (2006) implied in the title of their letter in the November 2006 issue of Environmental Health Perspectives, be dismissed by scientists, regulators, and others as simply a new faithbased religion? No. Hormesis is a data-based biological reality, one that challenges the lowdose assumptions that currently drive risk assessment processes used by regulatory and pub...
متن کاملHormesis and epigenetics: is there a link?
Epigenetic regulation of gene expression is a key molecular mechanism linking environmental factors with the genome with consequences for health status throughout the life course. According to the modern view, epigenetic changes are far more likely than genetic changes to be directed, and many of these changes are manifestly adaptive. Recent experimental studies clearly indicate that environmen...
متن کاملIs music an evolutionary adaptation?
In contemplating the function and origin of music, a number of scholars have considered whether music might be an evolutionary adaptation. This article reviews the basic arguments related to evolutionary claims for music. Although evolutionary theories about music remain wholly speculative, musical behaviors satisfy a number of basic conditions, which suggests that there is indeed merit in purs...
متن کاملHumans Have an Expectation That Gaze Is Directed Toward Them
Many animals use cues from another animal's gaze to help distinguish friend from foe. In humans, the direction of someone's gaze provides insight into their focus of interest and state of mind and there is increasing evidence linking abnormal gaze behaviors to clinical conditions such as schizophrenia and autism. This fundamental role of another's gaze is buoyed by the discovery of specific bra...
