Research led by the Department of Sociology & Anthropology at Ohio University has found evidence of hominin activity at a Romanian fossil site dating to at least 1.95 million years ago. This discovery pushes back the known date of European hominins by half a million years and establishes Grăunceanu as the oldest confirmed European evidence of hominin activity.

Grăunceanu, part of the Tetoiu Formation in Romania, lies within a Late Villafranchian biochronological zone (2.2–1.9 Ma) and has yielded a diverse faunal assemblage indicative of a forest-steppe environment.

The timing of the earliest hominin dispersals into Eurasia has been elusive. Fossil evidence from Dmanisi, Georgia (~1.85–1.77 million years ago) represents the earliest indisputable hominin presence outside Africa. Isolated sites in Europe and Asia with lithics and bone modifications suggest earlier, intermittent hominin activity. Until now, no European site had reliably demonstrated hominin activity predating ~1.4 million years ago with robust age determinations.

In the study, “Hominin presence in Eurasia by at least 1.95 million years ago,” published in Nature Communications, researchers analyzed faunal remains from Grăunceanu, a site in the Olteţ River Valley of Romania, identifying cut marks indicative of hominin butchery methods.

A total of 4,524 specimens were examined for surface modifications such as weathering, root etching, and anthropogenic cut marks. Linear marks were analyzed macroscopically and quantitatively using 3D optical profilometry.

Twenty bones exhibited anthropogenic surface modifications, including seven high-confidence cut-marked specimens. These marks were found on animal tibiae and mandibles, showing straight, transverse trajectories consistent with defleshing. Quantitative analysis confirmed their classification as cut marks, distinguishing them from carnivore, trampling, or excavation damage.

Seven dentine samples from Grăunceanu and two from nearby sites were dated using high-precision laser ablation U-Pb. The method yielded minimum depositional ages for the fossils ranging from 2.01 ± 0.20 to 1.87 ± 0.16 million years ago, averaging around 1.95 million years. These results align with prior faunal-based biochronological estimates and establish the site as the oldest known evidence of hominin activity in Europe.

Oxygen and carbon isotope ratios from a horse molar were analyzed to reconstruct seasonal temperature and precipitation patterns, suggesting a temperate woodland-grassland environment with higher (than modern-day) seasonal rainfall. Faunal remains, including ostrich, pangolin, and an extinct European monkey, suggest relatively mild winters despite the site’s mid-latitude position. Read More At Phys.org.

Spread the love In the quest to combat cancer, a disease that remains one of the leading causes of death worldwide, the medical community continually seeks innovative and alternative treatments. Here’s an overview of several unconventional approaches currently under investigation or discussion: Ivermectin and FenbendazoleIvermectin, traditionally an antiparasitic drug, has been studied for its potential antitumor effects. Research has shown that it can inhibit cancer cell proliferation, induce apoptosis, and modulate pathways like EGFR/ERK/Akt/NF-κB, potentially reversing drug resistance in cancer cells. Similarly, fenbendazole, another antiparasitic, has garnered attention for its potential in cancer treatment. There are anecdotal reports and some preclinical studies suggesting it might inhibit cancer cell growth. Both drugs have been part of protocols like the Joe Tippens Protocol, where they are combined with other supplements and dietary changes, showing some promise in case studies. Tata Institute’s Breakthrough in Cancer Drug DevelopmentThe Tata Institute has been at the forefront of cancer research, developing innovative drugs. One notable breakthrough involves targeting cancer cell metabolism with drugs that can selectively kill cancer cells while sparing healthy ones. Although specific details on the drug are sparse due to ongoing research, this approach aims at disrupting cancer’s energy supply, a novel strategy in cancer therapy. Small Extracellular Vesicles (sEVs)Small extracellular vesicles are nanometer-sized vesicles released by cells that can transfer molecular information between cells, including from cancer cells to healthy ones, influencing tumor progression. Research into sEVs focuses on their potential as biomarkers for early cancer detection and as carriers for therapeutic…
