For years, DNA analysis has helped scientists answer age old questions about evolution and human biology.  Genetic Anthropology has helped scientists map out human evolution and migration patterns that resulted in today’s many ethnic backgrounds. Behavioral Genetics has helped scientists better understand the conflict of nature versus nurture and identify several genes that do have an effect on such characteristics such as personality traits and sexual orientation. Genetics has also revolutionized the practice of medicine. Doctors and pharmaceutical companies now have a more basic understanding of how the biological processes work and how genes can affect our health.

With new innovations in gene sequencing, the discoveries in genetics are finally available to the public. Using a DNA test, a person can find the closest common ancestor with any living person Genealogy now allows people to explore the origins of their ancestors and what genes are specific to their ethnicities. Patients can be genetically tested for their natural predisposition for an array of diseases. Users of genetic testing kits are free to explore all the secrets that scientists can uncover in their DNA.
