Originally Answered: Whydoes the African continent havethe greatest amount of geneticdiversity (humans)?
Studies show the African continent contains the highest geneticdiversity of any place in the world, but whether or not that correlates to the highest variation in language isn't as clear.
Sub-Saharan Africahasthemost human geneticdiversity and the same has been shown to hold true for phenotypic variation in skull form. Phenotype is connected to genotype through gene expression. Geneticdiversity decreases smoothly with migratory distance from that region, which...
So much so that, if you were to study the two Africans mostgenetically different to each other, they would share less DNA than a Frenchman does with a
The sheer diversity in the African genome provides substantial power for genome-wide association
Africans are moregeneticallydiverse than the inhabitants of the rest of the world combined
Scientists have completed a comprehensive study of geneticdiversity in Sub-Saharan Africa.
Is Africa themost linguistically diverse place on Earth?
Look at all the countries in Africa--that is geneticdiversity. The caucasian skin/eye/hair tone itself was a mutation born out of a need to survive in colder
The origins of high geneticdiversity"Pretty much every study that's ever been done involving looking at genetic variation in Africans compared to non-Africans always
While South Africahas taken the unusual step of making so many of them official, the variety of
Africans are moregeneticallydiverse than the rest of the world combined. Modern humans evolved in Africa about 200,000 years ago, and began moving out.
The magnitude of geneticdiversity within human populations varies in a way that reflects the sequence of migrations by which people spread throughout the world.

Why is geneticdiversity important? How did the cheetahs lose geneticdiversity?
The importance of geneticdiversity. More specifically, geneticdiversity can be a species natural defence system against disease and survival even under extreme weather conditions but more importantly, geneticdiversity can help weed out unfavourable traits in species which maximises...
Researchers found significant diversity in the genetic makeup of a population from the southern region of
• Geneticdiversityhasmore potential to affect the species diversity than not. • Geneticdiversity may not be directly viewed, whereas species
What geneticdiversity tells us. Geneticdiversity is an important indicator of the health status of a
Recent work considering diversity at a genetic level has suggested that creatures thought to be a single species could in some cases actually be dozens.
"But in the medium-long term, geneticdiversity will become more important if those populations survive and we want them to thrive in the highly
Various populations have an increased frequency of genetic diseases, which are often unique. Probably a lot or most of it is just chance, but
Essentially, by having greater geneticdiversity within a fish species (e.g., many discrete populations with different life history strategies rather than a single homogenized population), the species is more apt to withstand variable conditions. Perhaps one year, one population does well and in another year...
Recent studies have established that Africahasthemostgeneticallydiverse populations with the oldest ancestry, deriving from 14
We havethe beginnings of an answer as to why, in some places, one snail species is so variable
The study demonstrates startling diversity on the continent, shared ancestry among geographically diverse groups and traces the origins of Africans
Given the importance of Africa to studies of human origins and disease susceptibility, detailed characterization of Africangeneticdiversity is needed. The African Genome Variation Project provides a resource with which to design, implement and interpret genomic studies in sub-Saharan...
While the intermediate level of geneticdiversity prevalent among the Asian and European populations has
Whydo genetic drift more likely to occur in smaller populations? Genetic drift is a random process. For example, say we had a small population of
Start studying GeneticDiversity. Learn vocabulary, terms and more with flashcards, games and other study tools.
This means Africans are moregeneticallydiverse than the people who colonized the rest of world. There is moregeneticdiversity in an African
A gene pool is the totality of genetic information in a species.
Geneticdiversity is the variation of heritable characteristics present in a population of the same species. It serves an important role in evolution by allowing a species to adapt to a new environment and to fight off parasites. It is applicable to domesticated species, which typically have low levels of...
Africanshavemoregenetic variation than anyone else on Earth, according to a new study that helps narrow the location where humans first
However, the genetic level forms the baseline. Geneticdiversity in organisms forms the root of any genetic adaptation or variability. It is the basis for evolution and natural selection. The geneticdiversity of a species paves the way for the species to be able to adapt to its changing environment.
Scientific American is the essential guide to themost awe-inspiring advances in science
Geneticdiversity is one aspect of biodiversity. While biodiversity is defined as the level at which variations exist within.
Scientists have made themost comprehensive map yet of Africangenetic variation and say it should help them learn more about the role genes play in
The genetic variation of an entire species is often called geneticdiversity. Genetic variations are the differences in DNA segments or genes between individuals and each variation of a gene is called an allele.For example, a population with many different alleles at a single chromosome locus has a...
The geneticdiversity on the X chromosome has a much stronger relationship to distance from genes than the autosome. This matters because as you
This also explains whyAfricanshave a higher variation. When the emigrating group separated from the larger group, only part of the gene pool was taken along.
The Genetics of Species’ Origins. Can enough geneticdiversity arise in a few thousand years to make the
Whydo these differences exist? The short answer is, of course, evolution. The groups exist because human populations have an evolutionary history, and, like different
Geneticdiversity is important because themoregenes are in a population, themore likely that one of those genes will prove helpful in the face of threats such as climate change or a new disease. Geneticdiversity is related to the ability of a species to adapt to a changing environment.
