<p>Recent discoveries in genetics have significantly changed our understanding of human history. A recent study focused on ancient bones found in Colombia has revealed some surprising insights. Researchers believe these remains come from a tribe that lived in the Bogotá Altiplano region for thousands of years, but their DNA shows no direct links to modern or ancient Colombians.</p>
<p>This study, published in 2025 in *ScienceAdvances*, investigated the demographic history of Colombia. For a long time, researchers knew very little about the ancient genetics of this area. Previous studies had only looked at mitochondrial DNA, which comes from mothers. This team went a step further, examining complete genomes to uncover the huge gaps in our understanding.</p>

<p>To gather data, researchers analyzed remains kept at the National University of Bogotá. They took DNA samples from 21 individuals found in five archaeological sites. Using advanced techniques, they could extract tiny samples of bone and tooth material, which enabled them to create comprehensive genetic profiles.</p>
<p>When they sequenced the DNA, the researchers found unexpected results. Some remains showed that individuals were distantly related, suggesting they lived in smaller, close-knit communities. However, the most shocking finding was that these individuals weren't part of the known migrations that shaped South America. Instead, they belonged to a much older genetic line, possibly linked to the foundations of other Indigenous groups in the region.</p>

<p>This research could rewrite the history of human migration in the Americas. Previously unknown lineages like this one highlight how early human populations thrived before eventually fading away. It’s reminiscent of past discoveries that revealed that humans were not the first inhabitants of North America.</p>
<p>The implications are fascinating. This group in the Bogotá highlands predates other known migrations. Researchers suggest they might have come from a central homeland, from which others spread out either northwards or southwards. When their lineage diminished, new groups took over, shifting the genetic landscape.</p>
<p>However, the study is just the beginning. It only examined 21 remains, and researchers stress that a larger sample size is essential for a clearer genetic picture. Future studies will likely continue to delve into ancient remains from various time periods, including western Colombia and regions in Venezuela. This could bring us closer to understanding the broader human story in South America, potentially leading to more exciting discoveries of ancient populations.</p>
