About this Research Topic

Background

The study of ancient DNA has revolutionized our understanding of human populations by providing insights into the genetic diversity and evolutionary history of our species. By analyzing DNA extracted from ancient remains, such as microorganisms found in mummified tissues, bone, and dental pulp, researchers can uncover the intricate relationships, migrations, and interactions between ancient populations. The integration of archaeological, anthropological, and genetic data has enabled the reconstruction of human history with unprecedented accuracy.

Recent advances in ancient DNA research, including high-throughput sequencing technologies, improved DNA extraction techniques, and enhanced analytical methodologies, have propelled the field to new heights. These advancements have facilitated discoveries by allowing scientists to explore the dynamics of ancient human populations with great precision. However, challenges such as the degradation and contamination of ancient DNA, complex laboratory protocols, and ethical considerations for sample acquisition remain significant hurdles that need to be addressed.

This Research Topic aims to showcase the breadth and significance of ancient DNA research in unraveling the history of human populations. It will provide a platform for researchers to present their findings on a wide range of topics, including paleomicrobiology, ancient migrations, population admixture events, genetic adaptations to changing environments, and the impact of ancient diseases on human populations. By addressing these areas, we hope to answer specific questions about the genetic structure and ancestral history of human populations, test hypotheses related to ancient genetic adaptations, and explore the origins and spread of pathogens.

We particularly welcome contributions of Original Research, Review, Mini Review, Systematic Review, Methods, Opinion, and Perspective articles on the following, but not limited to, subthemes:

• Detection, identification, and characterization of microorganisms in ancient remains, such as oral paleomicrobiology;
• Characterization and analysis of ancient microbiomes;
• Origins and spread of pathogens through history;
• Reconstruction of whole-genome sequences for ancient genome analysis;
• Genetic structure and ancestral history of worldwide human populations;
• Adaptation of ancient populations, and their microbiome, to their local environments.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
