But beneath its frozen surface lies a complex history of human migration, isolation, and adaptation. Because most genomic research has focused on people of European ancestry, existing diagnostic tools and treatments often fail when applied to non-European populations. For Greenlanders, this inequity is particularly severe.
An Ancient Practice, Revisited Through Code Knots are one of humanity’s oldest tools—so ancient, in fact, that they predate agriculture, metallurgy, and written language. Despite differences in time, geography, and material culture, many human groups developed the same set of knots—again and again.
The genetic legacy of Neanderthals persists in modern humans, with 1-2% of non-African genomes composed of Neanderthal DNA—a determination made through comprehensive sequencing and comparison of ancient and modern genomes. “These beneficial traits spread rapidly in early human populations.”
Human history is not just about where we came from but how we adapted to the ever-changing environments we encountered. Studies on mitochondrial DNA (mtDNA), which is inherited exclusively from the mother, found that all modern human mtDNA lineages trace back to a common ancestor in Africa, roughly 200,000 years ago.
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." Villalba-Mouco, V.,
A recent not-yet-peer-reviewed analysis 1 of ancient and modern genomes suggests that contemporary human Neanderthal DNA originated from a single, prolonged period of mixing approximately 47,000 years ago. Introduction A new study, recently released as a preprint on bioRxiv , sharpens the timeline for this crucial period in human history.
The evolution of the human brain is one of the most remarkable chapters in our species' history. With its unparalleled size and complexity, the human brain consumes a disproportionate amount of energy relative to the rest of the body. Squirrel monkeys ( Saimiri sciureus ), another large-brain species.
