DNA has moved beyond esoteric science and into the center of everyday conversations about identity, culture and politics. It’s also reshaping stories about the past as advances allow scientists to extract ancient DNA (aDNA) from skeletons found at archaeological sites.

With each ancient genetic sequence, scientists learn new information about how people moved around and interacted in the ancient world. In some cases, this has helped overturn theories and resolve age-old debates.

But the aDNA “revolution” has also caused friction among geneticists, archaeologists and others over how this research is done. As archaeologists who collaborate on aDNA projects, we’ve witnessed these tensions firsthand. What lies at the heart of this rift, and how can these disciplines work together to better research humanity’s past?

By Manisha SahuAmerica News World October 25, 2025A groundbreaking scientific study has shed new light on one of the most disastrous military campaigns in history — the ill-fated 1812 invasion of Russia by Napoleon’s Grand Army. While history has long focused on cold, hunger and the enemy as the main culprits, recent DNA evidence reveals that two deadly bacterial infections were stalking the…

A new study of human genetic variation in sub-Saharan Africa, where modern Homo sapiens are believed to have originated, helps to reveal the region's rich genetic history, with implications for understanding the complexity of early modern human evolution.

The largest genomic study ever conducted among the Khoe and San population groups in southern Africa reveals that these groups are descendants of the earliest diversification event in the history of all humans - some 100,000 years ago, well before the largely accepted  'out-of-Africa' migration date range of modern humans.
