Relethford considers racial labels as “a culturally constructed label that crudely and imprecisely describes real variation” (). Variation is real, exists, and has been structured by geography and migration, but the labels we use are a “crude first-order approximation” (). Ninety-five percent of the Haitian population are descendents of African slaves. The remaining five percent is White and/ or mulatto (persons of mixed heritage). While most Haitians share a genetic and historical background similar to that of other ethnicities in the African American Diaspora, the Haitian experience in America may be quite.

Africa is where modern humans evolved and is the starting place for the global expansion of our species (Stringer and Andrews ; Stringer ; Templeton ). African populations also have the highest levels of genetic and phenotypic variation among all by: Given that analyses of both genetic and cranial phenotypic variation suggest that African populations were differentiated prior to the dispersal out of Africa, it would be expected that ancestral NEA and HOA populations would be differentiated from each other (Campbell & Tishkoff, ;Gunz et al., ).
This pioneering volume summarizes the results of diverse research on Pleistocene environments and the cultural and biological evolution of man in Africa. The book includes chapters on Pleistocene stratigraphy and climatic changes throughout the African continent; on the ecology, biology and sociology of African primate and human populations.
Africa not only has the highest levels of human genetic variation in the world but also contains a considerable amount of linguistic, environmental and cultural diversity.
For example, more than 2, distinct ethno-linguistic groups, representing nearly a third of the world’s languages, currently exist in Africa Cited by: Joe Henrich recommends books on Cultural Evolution. What exactly is ‘cultural evolution’.
In the last years a lot of different disciplines—I have psychology and economics particularly in mind, but also parts of biology—have become increasingly convinced that, in order to understand humans and human behaviour, we need to take culture seriously. In most cases, the more common a cultural trait is in the population, the more likely it is for an individual to Culture and Evolution in African Populations book the opportunity to acquire it through social learning (15).

It is. in this respect that we can see that even a people’s technology is part of their by: This book is a comprehensive and detailed account of how genetic and cultural evolution can interact, such as the coevolution of lactose tolerance alleles and dairy farming, or yam cultivation and sickle cell anemia.

Defining culture For most of the twentieth century, evolutionary theory focused on phenotypic variation underpinned by inherited genetic variation. Characterizing human genetic variation and examining phenotypic variation in extant African populations is fundamental to the identification of genes that play a role in function, adaptation, and complex disease susceptibility in Africans and populations of recent African descent.
Africa is the birthplace of modern humans, and is the source of the geographic expansion of ancestral populations into Culture and Evolution in African Populations book regions of the world. Indigenous Africans are characterized by high levels of genetic diversity within and between populations.

What Is Culture. Anthropologists commonly use the term “culture” to describe shared patterns of meaning that are learned within a particular social world—“that complex whole which includes knowledge, belief, art, law, morals, custom, and any other capabilities and habits acquired by man as a member of society” 1 or “patterns, explicit and implicit, of and for Cited by: Summary.
The identification of genetically coherent populations is essential for understanding human evolution. Among the culturally uniform ethnic groups of west Africa, there are two geographically distinct populations with high frequencies of sickle-cell hemoglobin (HbS).Cited by: Genetic variation occurs mainly through DNA mutation, gene flow (movement of genes from one population to another) and sexual reproduction.
Since environments are unstable, populations that are genetically variable will be able to adapt to changing situations better than those that do not contain genetic : Regina Bailey. Gene flow is any movement of genes from one population to another and is an important source of genetic variation.
Sex can introduce new gene combinations into a population. This genetic shuffling is another important source of genetic variation. #N#Genetic shuffling is a source of variation. Mechanisms of change. The median frequencies of null CYP2D6 alleles vary from 6% in Asian populations to 7% in African populations and 26% in European populations Thus, there is substantial population variation Cited by: Africans have more genetic variation than anyone else on Earth, according to a new study that helps narrow the location where humans first evolved, probably near the South Africa-Namibia border.
African populations will shed light on many ques-tions about human evolutionary history and the genetic basis of phenotypic variation. However, despite the important contributions that studies of African populations can make, these populations have been understudied compared with non-African by: Helgason, A.

Generally, for Africa, consistent with an African origin of humans.
Genetic variation is important to the processes of natural selection and biological evolution. The genetic variations that arise in a population happen by chance, but the process of natural selection does not.
Natural selection is the result of the interactions between genetic variations in a population and the environment. The environment Author: Regina Bailey. Why do African populations of humans have higher levels of genetic variation compared to non-African populations.
- Humans originated in Africa, and subsequent migrations resulted in populations seeded by small groups with relatively small amounts of variation.
- Because African populations show strong patterns of assortative mating. Over a period of two generations, the frequency of green dung beetles in a population shifts from 75% to 71% while the frequency of brown dung beetles within this population shifts from 25% to 29%.
This is an example of. Human genetic variation is the genetic differences in and among may be multiple variants of any given gene in the human population (), a situation called two humans are genetically identical.
Even monozygotic twins (who develop from one zygote) have infrequent genetic differences due to mutations occurring during development and gene copy-number variation.
Typically, people thinking about human evolution have approached this as a two-part puzzle, as if there was a long period of genetic evolution until eit years ago or 40, years ago, depending on who you're reading, and then only after that did culture matter, and often little or no consideration given to a long period of interaction.
Search the world's most comprehensive index of full-text books. My library. by Aaron Jonas Stutz Originally published 22 Mayupdated 15 Sep & 24 Aug CC-BY "Biocultural evolution" is a really useful phrase for anthropologists.
Many of us agree that the term captures something fundamental about humanity's identity, about our place in the world.
The phrase efficiently points toward the simultaneous tension. This book is a biogeography of diseases, culture, and historical development. Print. Evidence for Evolution. Populations, Species, and Evolution Variation and Evolution in Plants. 2 Sober and Wilson () note that there is a gap in their model of cultural evolution: "We can say that functionless [relative to human individual and group fitness] behavior should be more common in humans than other species, but we cannot explain why a particular functionless behavior has evolved in a particular culture.
The theory of evolution by natural selection was proposed roughly simultaneously by both Charles Darwin and Alfred Russel Wallace, and set out in detail in Darwin's book On the Origin of Species. All the other L groups are African populations: L0 is the San people, L1 is Mbenga pygmies, L5 is Mbuti pygmies, and the others are other African groups.
If one considers each L haplogroup to represent genetic variation then 5/6 (83%) of human genetic variation is from African populations. Evolution is change in the heritable characteristics of biological populations over successive generations.
These characteristics are the expressions of genes that are passed on from parent to offspring during ent characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation.

My lab studies human evolution, ancestry, genetic variation, and disease risk in populations around the world. We aim to answer fundamental questions about human origins, focusing on Africa’s role as the place where modern humans originated and thus the region with the most genetic diversity.
How Climate Change May Have Shaped Human Evolution diverse food options during variable periods even as the African landscape was, in the long term, trending toward a more uniform grassland Author: Brian Handwerk.South African ethnic groups are also found across South Africa's boundaries in neighbouring countries.
For example, Nguni-speaking Swazi people make up almost the entire population of Swaziland. At least million Sesotho speakers live in Lesotho, and more than 1 million people in Botswana speak Tswana.T he A blood allele is somewhat more common around the world than B. About 21% of all people share the A allele.
The highest frequencies of A are found in small, unrelated populations, especially the Blackfoot Indians of Montana (%), the Australian Aborigines (many groups are %), and the Lapps, or Saami people, of Northern Scandinavia (%).
