Human genetic variation is the genetic differences in and among populations. There may be multiple variants of any given gene in the human population ( alleles ), a situation called polymorphism . No two humans are genetically identical.
Human evolutionary genetics studies how one human genome differs from another human genome, the evolutionary past that gave rise to the human genome, and its current effects. Differences between genomes have anthropological , medical , historical and forensic implications and applications.
Macroscale models can include ordinary, partial, and integro-differential equations, where categories and flows between the categories determine the dynamics, or may involve only algebraic equations. An abstract macroscale model may be combined with more detailed microscale models. Connections between the two scales are related to multiscale ...
Moreover, distinctions made between the creation of foreign people groups and the tribe or ethnic group to which the creation myth pertains served to reinforce tribal or ethnic unity, the need to exercise wariness and caution when dealing with outsiders, or the unique nature of the relationship between that tribe and the deities of their ...
Researchers have investigated the relationship between race and genetics as part of efforts to understand how biology may or may not contribute to human racial categorization. Today, the consensus among scientists is that race is a social construct , and that using it as a proxy for genetic differences among populations is misleading.
Researchers found that people worldwide live 9.6 years longer than they are healthy — and in the U.S. the gap is ... The difference between the average lifespan, minus the number of unhealthy ...
Psychologists Arthur and Elaine Aron are known for research behind the “36 Questions That Lead to Love.” They share how their relationship has lasted over 50 years.
Human study of economics is a social science that looks at how societies distribute scarce resources among different people.
