Like many other medical conditions, obesity is the result of an interplay between environmental and genetic factors. [2] [3] Studies have identified variants in several genes that may contribute to weight gain and body fat distribution, although only in a few cases are genes the primary cause of obesity. [4] [5]
Thus, genetic material that is transferred from a non-kosher species is no longer considered food, as it does not have taste and is considered separate from the non-kosher species. Rabbinic authorities generally assert that genetic material from non-kosher species is not in itself non-kosher and does not render the new organism non-kosher. [7]
[9] [10] [11] Phenotypes found to be largely environmentally determined in humans include personality, height, and weight. [ 12 ] [ 10 ] [ 13 ] [ 14 ] Twin studies have shown that more than half of the variation in a few major aspects of personality are environmentally determined, and that environmental factors even affect traits like immune ...
Recurring cultural, political, and theological rejection of evolution by religious groups [a] exists regarding the origins of the Earth, of humanity, and of other life. In accordance with creationism, species were once widely believed to be fixed products of divine creation, but since the mid-19th century, evolution by natural selection has been established by the scientific community as an ...
The God gene hypothesis proposes that human spirituality is influenced by heredity and that a specific gene, called vesicular monoamine transporter 2 (VMAT2), predisposes humans towards spiritual or mystic experiences. [1] The idea has been proposed by geneticist Dean Hamer in the 2004 book called The God Gene: How Faith is Hardwired into our ...
Religious stratification is the division of a society into hierarchical layers on the basis of religious beliefs, affiliation, or faith practices.. According to Kingsley Davis and Wilbert E. Moore, "[t]he reason why religion is necessary is apparently to be found in the fact that human society achieves its unity primarily through the possession by its members of certain ultimate values and ...
The isolationist practices of endogamy may lead to a group's extinction, as genetic diseases may develop that can affect an increasing percentage of the population. However, this disease effect would tend to be small unless there is a high degree of close inbreeding, or if the endogamous population becomes very small in size.
Hereditarianism is the research program according to which heredity plays a central role in determining human nature and character traits, such as intelligence and personality. Hereditarians believe in the power of genetic influences to explain human behavior and solve human social-political problems.
