As the exciting field of aDNA matures, new scientists will take the lead, new questions, methods, and practices will take form, and new discoveries will undoubtedly be made.<\/h2>\n

Ancient DNA<\/a>, or aDNA, is the acquisition, extraction, and study of DNA sequences collected and amplified from ancient remains. Human aDNA is, therefore, DNA from ancient humans who lived hundreds or even thousands of years ago.<\/p>\n

The Pros of Studying aDNA<\/h2>\n

aDNA research is one of the most inspiring and informative research fields in human research today. Research has already revealed some previously unknown facets of our species\u2019 history. For example, we share bits of DNA with Neanderthals and Denisovans. Additionally, decoding ancient genomes can reveal how and when diseases arose and whether we are still vulnerable to them.<\/p>\n

The Cons of Studying aDNA<\/h2>\n

Despite beneficial research, one question remains: how does a scientist strike a balance between the necessity of preserving the past and advancing research?<\/strong> That\u2019s because aDNA requires the partial destruction of human remains in order to get to the DNA code. The destruction of aDNA should immediately give scientists pause. After all, those are our own ancestors. Scientists must always remember the remains deserve dignity and respect while giving them a place in history.<\/span><\/p>\n

Examples of aDNA research<\/h2>\n

aDNA is a fast growing field. As of 2023, there have been over 10,000 ancient genomes sequenced<\/a>. These samples have brought clues and answers to how ancient civilizations lived and migrated throughout history.<\/p>\n

aDNA in Scandinavian Populations<\/h3>\n

Over the last fifteen years of aDNA research, nearly 10,000 individuals have been identified and researched. Most were sequenced as part of landmark scientific papers. One of those papers was the 2020 Nature<\/em> publication titled “Population genomics of the Viking World.<\/span><\/a>” Scientists sequenced the genomes of more than 400 individuals from archaeological sites across much of Europe and Greenland.[\/vc_column_text][vc_single_image media=”77012″ caption=”yes” media_lightbox=”yes” media_width_percent=”62″ lbox_caption=”yes” lbox_social=”yes” uncode_shortcode_id=”702376″][vc_column_text uncode_shortcode_id=”663413″]In their research They were able to reconstruct the spread of Scandinavian populations across Europe and the North Atlantic during the Viking Age. As the Vikings conquered, so did their DNA. Genes associated with light skin pigmentation and lactase persistence (The unique ability to digest milk) became associated with the population.<\/p>\n

aDNA in Caribbean Populations<\/h3>\n

The paper looked at genome-wide<\/a> data from 93 ancient humans that had once lived across the Caribbean. Their research showed that the islands\u2019 early settlers arrived thousands of years ago, from multiple regions and at different times. Their DNA still resides in millions of people living in the Caribbean today.<\/p>\n

aDNA in Virology<\/h3>\n

Researchers used a multi-method approach to reconstruct the detailed life history of three 16th-century Mexicans of African descent. The study also looked at viral DNA extracted from the remains. They gained an understanding of the evolution of human diseases, specifically yaws<\/a> and hepatitis B. The team went beyond the limits of ancient genomes to uncover a more detailed story of these individuals.<\/p>\n

FamilyTreeDNA and aDNA<\/h3>\n

[\/vc_column_text][vc_single_image media=”77006″ caption=”yes” media_lightbox=”yes” media_width_percent=”65″ lbox_caption=”yes” lbox_social=”yes” uncode_shortcode_id=”108706″][vc_column_text uncode_shortcode_id=”196732″]Due to aDNA research, we are now able to unearth new stories and tell the forgotten history of these ancestors. Scientists at FamilyTreeDNA have begun to compare the paternal lineages of thousands of ancient individuals to those of us living today, affording them a new place in our history. With FamilyTreeDNA Discover\u2122<\/a>, you can match your Y-DNA<\/a> to that of nearly two thousand men who lived across the globe. Our Big Y-700<\/a> test offers a detailed look at the millions of DNA markers men carry on their Y chromosomes. With that data, we can learn what markers we share with aDNA.
