The genealogical DNA test that is readily available for any one to take has been refined over the years to give accurate and informative information about the ancestral past of the subject. Because of the popularity of this kind of test, the prices have decreased in recent years making the availability of even more results and family lines available for genealogist to use in their work.

The simplicity of the test makes it possible for most anyone to take the sample at their home. This helps to avoid an unnecessary expense of traveling to a certified laboratory and having a technician take the sample.

A sample is taken by rubbing a cotton swab, or a provided paddle type scraper, on a person’s cheek inside the mouth. This collects numerous cells that contains the DNA. This sampling technique is the simplest that can be used. The only decision a person needs to make is how thorough of a test that is to be conducted should be. The more markers that are identified, the more information can be discovered.

There are two distinctly different tests that can be conducted. The Y DNA is for the father’s lineage while the mtDNA is from the mother lineage. With the Y DNA, there are repeating nucleotides that are called Short Tandem Repeats (STRs) that are identified. There are over 100 of these present but the maximum testing usually only contains 67 of them for thorough results.

With mtDNA, the Single Nucleotides Polymorphisms (SNPs) are tested. These are passed down from every mother to her children without mutations. This is a stable DNA that can be traced back in time to which Haplogroup a person originates from. The basic test involves 12 markers but just like the Y DNA, up to 67 markers can be identified and used for analysis.

Depending on the thoroughness of the desired results, a genealogical DNA test can range in cost from just under $100 up to $700. The choice is that of the person desiring the results.

A new DNA database is under development after scientists believe they may have found a new species of human.

High in the Altai mountains in southern Siberia in the Denisova cave, Russian archealogists unearthed the finger bone of a young child in 2008. The child was believed to be 5 to 7 years old at the time of death and the bone was tested for mitochondrial DNA.

Now scientists wonder if a new branch of the human family tree existed between Homo erectus that left Africa two million years ago and Neanderthals that left 500,000 years ago.

The Denisova child is believed to come from a form of human that left Africa about one million years ago. Researchers caution that the child may not belong to a new species of human, but from a small population formed by interbreeding among lineages. The remainder of the child’s DNA from the nuclear genome will be tested to determine this.

Radiocarbon dating first established the timeframe of the child’s death, estimating the boy or girl lived during the Pleistocene Ice Age between 48,000 and 30,000 years ago. Because the earth’s climate was much colder at that time, it’s likely the child wore some form of clothing.

Scientists were surprised to unearth more modern artifacts at the site too, such as jewelry. This kind of object was more indicative of modern humans in Europe so scientists will try to determine if the objects were related or they were left behind by other cultures through the ages.

This discovery debunks the linear theory of genealogy and will eventually affect family DNA surname projects. Until recently scientists believed there was a linear development of the human species, beginning with Homo erectus then Neanderthal and finally modern humans, Homo Sapien.

This new branch or potential new species will surely add to the growing DNA database growing daily around the world.
