Researchers found that each of the seven individuals had different marriage lineages. Two of the people—one a possible member of the ruling dynasty, and the other a victim of—belonged to the same Y-chromosome haplogroup. A haplogroup is a population that has the same genetic markers passed down by a common ancestor. However (though this seems remarkable), it doesn’t mean that the two individuals were closely related.

“Even though the dynastic ruler and the sacrificed individual share the same Y-chromosome haplogroup,” Nakagome told Live Science, “we did not find any kinship.”On top of comparing the individuals’ genomes to each other, researchers also compared the sets with previously sequenced genomes from across the Americas and Siberia. The scientists found strong evidence of genetic continuity between ancient and modern Maya people, suggesting “the enduring persistence of local ancestry in the Maya region,” according to the study. Researchers also found an influx of people with ancestry from highland Mexican populations extant during the early to mid-Classic period.could have been part of the dynasty of Copán.

Finally, researchers used time-stamped genomes to estimate population sizes at different points in time. The study determined that Maya society saw a sharp increase in population that peaked around 730 A.D. at 19,000 people. According to researchers, the spike likely occurred thanks to the emergence of maize agriculture. Researchers saw a subsequent decline in population around 750 A.D., “coinciding with the onset of the collapse of Classic Maya civilization,” according to the paper.The scientists on the study juggled many questions while conducting their research, which ultimately furthers our understanding of both the ancient and contemporary Maya people.

“[O]ur research offers a new perspective, suggesting the enduring persistence of local ancestry in the Maya region,” the researchers wrote, “while also highlighting the broader mobility beyond the conventional boundaries of the Maya territory.”

A man has been found dead and his daughter remains missing while attempting to hike to the summit of Mount Katahdin in Maine, officials said Tuesday."Authoritarian governments often choose to silence and forget history, while democratic societies choose to preserve the truth and refuse to forget those who gave their lives - and their dreams - to the idea of human rights," he added.

"Not only do we refuse to forget history, we will implement our core values every day."U.S. Secretary of State Marco Rubio on Tuesday praised the courage of the Chinese people who were killed in the bloody crackdown.

"Today we commemorate the bravery of the Chinese people who were killed as they tried to exercise their fundamental freedoms, as well as those who continue to suffer persecution as they seek accountability and justice for the events of June 4, 1989," Rubio said in a statement."The CCP actively tries to censor the facts, but the world will never forget," he said, referring to the Chinese Communist Party.
