Epigenetic hypothesis
WebApr 7, 2024 · If epigenetics can mediate a transgenerational inheritance of behavioral biases (either behaviorally mediated or by direct molecular actions), this would provide a mechanism for the rapid transformation of learned behavior to an instinct. However, our hypothesis does not depend on such direct effects. WebThe thrifty gene hypothesis argues that those who can absorb and process food efficiently have survival advantages during a historical time when human were subject to frequent cycles of feast and famine. Such trait, however, becomes maladaptive in an environment with constant abundance of food, leading to metabolic diseases.

The term epigenetics in its contemporary usage emerged in the 1990s, but for some years has been used with somewhat variable meanings. A definition of the concept of epigenetic trait as a "stably heritable phenotype resulting from changes in a chromosome without alterations in the DNA sequence" was formulated at a Cold Spring Harbor meeting in 2008, although alternate definitions that include non-heritable traits are still being used widely.
