One of the most intriguing chapters in human evolution is the story of the Denisovans, a mysterious, now-extinct hominin group that left a significant genetic footprint in the DNA of modern humans. Overview of the distinct Denisovan populations that introgressed into modern humans.
Traditional ancestry reports often provide a static snapshot, indicating, for example, that an individual is "50% Irish." While informative, this perspective oversimplifies the intricate tapestry of humanancestry, which is more akin to a dynamic film than a still photograph. Credit: Science (2025).
Neanderthals and Homo sapiens are both humans, but they differ in many ways. This research challenges prevailing assumptions about speciation, offering a more nuanced framework for interpreting the evolutionary history of modern humans and their closest relatives. What Defines a Species? ” Dr. . J., & Conde, C.
A groundbreaking genetic study conducted by researchers at the RIKEN Center for Integrative Medical Sciences has uncovered new evidence that challenges the longstanding belief in a dual-origin model of Japanese ancestry. This study shows that their genetic legacy persists, with their ancestry decreasing as one moves westward across Japan.
A recent study, published in the European Journal of Archaeology 1 , suggests these plaques may represent one of humanity's earliest attempts at recording genealogy—a non-verbal precursor to modern ancestry documentation. Eventually, these designs were manipulated to convey more precise genealogical information."
More than 46,000 years ago, deep within the caves of what is now northern Spain, a silent drama unfolded between humans and the great beasts of the Ice Age. More importantly, the study provided evidence that humans and large carnivores—like hyenas and leopards—coexisted in Iberia for much longer than previously thought.
Lagging behind in scientific understandings of human diversity, the medical profession is failing its oath to “do no harm.” ✽ Doctors lie daily. By checking “Patient’s Race,” we health care providers pretend to know something that we cannot possibly know: the patient’s ancestry and associated medical risk.
schools stokes misconceptions about race and human diversity. On the bus, Lewontin turned his attention to humans. His results have been replicated time and again over the last 50 years, as datasets have ballooned from a handful of proteins to hundreds of thousands of human genomes.
The findings, published in Nature Communications 1 , reveal a wealth of information about the boy's ancestry, physical traits, health, and the environment in which he lived, offering a rare glimpse into the lives of prehistoric humans. Genome sequence of a 45,000-year-old modern human from western Siberia."
Leave this field empty if you're human: Reagan said she has done long-term projects before, but never something so important to her personally and never as the centerpiece of an entire class. “It Sometimes kids found unexpected ancestries – like one white student who found an ancestor labelled “mulatto” on an old Census. Weekly Update.
The study suggests that Neanderthals organized in smaller, more isolated groups, while early modern humans maintained broader social connections, which may have contributed to their survival. This genome is from a distinct lineage of late Neanderthals, adding new information to the complex history of the species. Photo: Xavier Muth.
The Oakhurst rock shelter, nestled in the cliffs of South Africa’s southern coast, has long been a focal point for archaeologists due to its wealth of artifacts and human remains. These findings offer a new perspective on human population stability and cultural evolution in southern Africa. 1 Gretzinger, J., Gibbon, V.
There’s an ugly history of proponents of eugenics , who believe in reshaping humanity by breeding “superior traits” and removing “inferior traits,” justifying their thinking with genetics. There is also an enormous shortcoming in the datasets used for this research: Virtually all are built with DNA from people of European ancestry.
Through this work, drawing on knowledge from human skeletal biology, anatomy, and archaeology, we often confront the immense social and racial inequalities that can play a role in the circumstances of ones death. We are humans asking questions about the world around us. and around the world.
million people , about 82 percent of whom are of Norwegian ancestry, across a space roughly the size of Montana. Programs must be rooted in values including forgiveness, equality, solidarity and respect for human worth. Credit: Jackie Mader/The Hechinger Report To be sure, there are important contexts behind each country’s approach.
Human teeth are small marvels of biology, carrying genetic signatures that reflect millennia of evolutionary change. Dr. Kaustubh Adhikari, a UCL researcher and one of the study’s authors, emphasizes the significance of teeth in understanding humanity's past.
published in The American Journal of Human Genetics 1 , has provided fresh insights into the complex origins of the Fulani, tracing their ancestry back to an ancient, lost world—the Green Sahara. How did their nomadic culture evolve? Now, a groundbreaking genetic study by Fortes-Lima et al.,
For visitors to the exhibit and those who access the array of resources on the projects website, the information brings cutting-edge, eye-opening knowledge about race and racism. Remaining also are the human stories of those harmed by racism. Remaining also are the human stories of those harmed by racism.
