Rather than a single lineage evolving smoothly over time, the evidence suggests a history of separation and recombination," says Cousins. This approach circumvents the need for physical fossils, offering a way to reconstruct population history even when no bones or artifacts remain. Ragsdale, A. Nature , 617(7962), 755–763.
A recent study led by researchers from London’s Natural History Museum and the KU Leuven Institute of Philosophy reignites the debate over whether Homo sapiens and Neanderthals ( Homo neanderthalensis ) should be classified as separate species. Journal : Quaternary Science Reviews , 2023. What Defines a Species?
These genetic signatures match the so-called "Fournol cluster" of Gravettian ancestry, suggesting that a distinct population survived in this region through the Last Glacial Maximum.

Tracing Ancestry and Diet Chemical analyses of teeth revealed that some early North American horses were raised locally, while others were part of managed herds fed maize. DNA comparisons with modern horses showed these early horses were primarily of Spanish ancestry. Librado, P., Hunska Tašunke Icu, M., Shield Chief Gover, C.,
Each discovery reshapes our understanding, challenging erstwhile beliefs, and heralding a paradigm shift in our comprehension of history. Notably, miscalculations in dating methodologies have led to significant misconceptions in human evolutionary history. 1 Grün, R., & Stringer, C.
He did, and Livingston soon found herself sitting in an introductory college course in US history. The next semester, she took two more US history classes, then realized she’d found her major. The next school year, she was asked to teach not only the regular-level geography course but also AP Human Geography and World History.
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. Now, a groundbreaking genetic study by Fortes-Lima et al., But as this study shows, the answer lies much closer to home.
In 2023, a dramatic claim in Science 1 suggested that human ancestors teetered on the edge of extinction around 900,000 years ago. Inferring human population size and separation history from multiple genome sequences. Inference of human population history from individual whole-genome sequences. DOI: 10.1038/ng.3015 Prufer, K.,
Largest Dataset to Date The researchers analyzed the most extensive dataset of human fossil evidence ever compiled, spanning seven million years of evolutionary history. However, the new study challenges this idea, presenting a more nuanced perspective of incremental growth. Source: Philosophical Transactions of the Royal Society B.
